NEW FACULTY: Er. Allan Showalter ijoined the staff of the Department of Botany this year after completing a three year postdoctoral appointment at Washington University, St. Louis. Allan received his B.S. degree in 1978 from Franklin and Marshall College and his Ph.D. in 1983 from Rutgers University. Ha is also affiliated with the Molecular and Cell Biology Program and a portion of his funding comes from a $269,000 first year Academic Challenge Grant through Ctiio’s Selective Excellence Initiative. A major focus of his research is the isolation and characterization of plant hydroxyproline glycoprotein genes and their expression under stress conditions.

Adams, who has been working on the population biology of the rare fern (in chio), Lorinseria areolata. Other faculty receiving Research Challenge support include Gayle Muenchow, Gar Rothwell, Norman Cohn and John Mitchell. AWARDS: The Department held its annual awards ceremony on May 1 at the Window Room of Baker Center to honor academic achievement by undergraduate majors. Graduating seniors receiving awards were Edwin Frebault Cfiela biology), Marcella Grebus (cell biology), Kevin Blake, Leslie Dybiec (senior Wolf Award in conservation), Anna Anagnostopolous (outstanding senior from the Honors Tutorial College), and Jackie Adams (outstanding senior from the College of Arts and Sciences). In addition, Stocker Scholarships for the 1987—88 academic year were awarded to Sing Han Kim and Anthony Kirchgessner, and the junior Wolf Award in conservation went to Andrew Swanson. F’ebault, Grebus, Blake, Anagnostopolous, and Adams were also recognized by the Botanical Society of America for showing exceptional promise for future work in the botanical sciences. Almost all of the graduating seniors will be attending graduate school. The ceremony was attended by about 70 people, including parents and relatives of the awardees, current and emeritus faculty (Ers. Wistendahl and Vermillion) of the department, Associate Dean Molineau, Margaret Cohn, Director of the Honors Tutorial College, Irene Roach, former Director of Graduate Student Services, and undergraduate and graduate students in the department.
GRANTS: Er. Gayle Muenchow has received a two year grant fran the National Science Foundation to study clioecy and nxnoecy in the two closely related species of Sagittaria (Alismataceae). The grant includes funds for a post doctoral fellow and Veronique Delesalle will be joining h lab shortly in this position. Veronique is currently cctnpleting her doctorate at the University of Arizona working on monoecy in Cucurbitaceae. James C. Cavender has received a grant from the National Science Foundation, Division of International Programs, to study the taxonomy and distribution of cellular slime molds in the Central African Republic. Other faculty receiving grants include Gene Mapes, from the Chio University Research Committee, to study the relationship of wildfire and early Conifers. Research Challenge Awards from Chio University re given to Irwin Ungar for purchase of new equipment and technical help, Philip Cantino, for the services of a biological
glandular hairs that cover the foliage of most mints. These glands secrete the chemical compounds responsible for the “minty” odor the family is known for. Understanding the ylogeny of the mint family will ultimately lead to a more jredictable classification, because plants grouped together on the basis of recent common ancestry should be more similar genetically and thus share more traits in common than distantly related plants. Predictability is an important feature for a classification to have because it permits the user to predict things about a plant simply by knowing its position in the classification. Predictivity extends to characteristics that were not used to construct the classification. For example, even if chemical features were not used by the taxonomist, the classification should still be rredictive about chemistry if the phylogeny it is based on is accurate. Dr. Cäntino’s phylogenetic classification of the mint family should permit a chemist who discovered a commercially useful compound in one member of that family to predict which other members are most likely to produce the same compound (i.e. those that share the closest common ancestry with it). This could be of considerable importance if the plant the compound was initially found in was rare or difficult to grow. Nones Abu—Asab’ s doctoral research is an investigation of the pollen morphology of a large subfamily of Labiatae, using scanning and transmission electron microscopy. Jon Hamer, another doctoral student, is working toward a taxonomic monograpi of the Pycnanthemum incanum species complex (Mountain Mints), based upon morphological variation, chromosome number, and enzyme systems (as determined through
JAMES P. BRRSELTON: Dr. &aselton visiteJThhe Kraft microstructure group at the technology center of Kraft, Inc., Glenview, illinois, for a wec in March to learn applications of light microscopy, scanning electron microscopy, and transmission electron microscopy for basic studies of food microstructure. He is an invited speaker for a colloquiun on “Viruses and Fungal Vectors” to be held in St. Pndrews, Scotland, at the end of Pugust, where he will review basic studies on ultrastructure of development of the Plasmodiophoromycetes. F is teaching Botany 100 (The World of Plants), a course of his own design, which continues to increase in enrollment. This past quarter enrollment was 320 and he is “shooting for Memorial Auditorium.” PHILIP D. CANTINO The principal focus of Dr. Cantino’s research continues to be on reconstruction of the phylogeny of the Labiatae (mint family) and revision of the classification of the family to reflect phylogenetic relationships. Toward this end, he is employing cladistic analysis, a method that attempts to delimit heirarchies of monophyletic groups (the “clades” or branches of the monophyletic tree). These groups are circumscribed on the basis of shared derived traits——evolutionary markers that evolved in the ancestor and were inherited by the descendents. The data on which the cladistic analysis is based are derived from an ongoing survey of morphological and anatomical variation in the family. Characteristics under study by Dr. Cantino and graduate student Mones Abu—Asab include flower and fruit structure, leaf anatomy, pollen surface sculpturing, and the microscopic structure of the tiny
starch gel electrophoresis). Greg Rhinehalt is approaching completion of his dual masters degrees in botany and environmental studies. His research, which is funded by a grant from the Divisict of Natural Areas and Preserves of the Ohio Department of Natural Resources, concerns the taxonomy and ecology of Trollius laxus (Spreading Globeflower), an dangered species in Ohio. Late in 1986, Steve Harriott completed his masters thesis in environmental studies with a study of the variation and land use history of a Nature Conservancy rreserve in Pike County, Ohio, with management recctnmendations. As of Fall Quarter, 1987, Lr. Cantino will be promoted to Associate Professor with tenure. He has also been elected to the Board of Trustees of the Ohio Chapter of the Nature Conservancy (May, 1986) and wiil serve a three year tenn. In summer, 1986, he presented a paper (A systatic survey of leaf epidermal features in the Labiatae) at the annual meeting of the Botanical Society of America in t4iuherst, Massachusetts. This past November, he presented a seminar (Phylogenetic systematics of the Labiatae) at Miami University in Oxford, Ohio.
Barbara ]3allard successfully defended her dissertation Mycorrhizae of Some Inland Halophytes in March. Michael Quinones is collecting forest soils in California this June for making isolates of West Coast dictyostelid slime molds as part of nis masters thesis research. Steven Rioch, an Honors Tutorial Student in botany, has begun a 4000 sq. ft. (40 deep beds) minifarm at the West State Street Experimental Garden site and has submitted a grant proposal to sympathetic parties for fUnding. The purpose is to show the economic viability of a small food—producing unit and to provide instruction for students in the new Tier III Alternative Agriculture course. Gary Kauffman and Chuck Hammer are both working in Ohio helping save endangered habitats and plants. Dale Anderson is currently living in Spain with his family.” NORMAN S. COHN: Dr. Cohn is currently producing pea cDNA clones of sequences involved in the response of gibberellic acid by dwarf mutants. Several monoclonal antibodies have bei producel that reveal specific çrotein localization in developing pea shoot tissue. He participated in a symposium on the physiology of cell expansion during plant growth at Pennsylvania State University in May, 1987 and last summer presented a paper to the annual meetings of the Botanical Society of America at Amherst, Massachusetts. This June, he will be speaking on his research to the Botany Department at Ohio State University.
JAMES C. CAVENDER: Dr. Cavender reportiThhat “I spent two months searching for cellular slime molds in Japan working with three Japanese colleagues at Shizuoka University, The National Museum, Tsukuba, and Kushiro College, Hokkaido. Japan still has 70% of her area in forest and is a refuge for many species of cellular slime molds. This research was funded by OURC. In July, I wiil travel to the Central African Republic to study the effects of slash and burn agriculture on soil microbes, particularly the slime molds. This research is being funded by NSF.
ROBERT M. LLOYD: Dr. Lloyd continu his research on population biology and genetics in ferns. The major emphasis of the research is to document genetic variation in fern populations and the influence of breeding systems, vegetative reproduction, and colonizing effects. He is currently LI
trying to complete a book on the evolutionary biology of ferns and will spend this summer completing a chapter cri sexual reproduction and genetic variation in natural populations. Two graduate students, Steven J. Wagstaff and Robert Hamilton, have recently joined his lab, working for their doctorates. Steve Wagstaff received his masters degree fran Western Washington and is working on intra— and interpopulational genetic variation in the climbing fern, Lygodium palmatum. This species is one of two temperate species in the genus and is localized and somewhat rare in Ohio. Practically nothing is known about the biology of the species and his work will also document gainetophyte morphology, breeding systems, and extent of vegetative reproduction. &b Hamilton is studying the demography of two species of Athyrium in southeastern Ohio. He is documenting life—history stages and various physiological and ecological factors in the field and will genotype individuals using restriction DNA mapping as well as isozyme variation (with starch gel electrophoresis). This coming fall, Ma Yilun, from Beijing, thina, will be joining the lab to work on his doctorate and Winter iarter, Jackie Adams will initiate doctoral work on the population biology and genetics of Lorinseria areolata and other members of Woodwardia s.l. in the eastern United States. This coming summer, Dr. Lloyd will complete his six year term as a member of the Council of the International Association of Pteridologists.
America, especially Kansas, Oklahoma, and Texas, where permineralizect fossils reveal both anatomy and morphology of ancient conifers, plus a broad spectrum of associated plants and animals. She has recently discovered charcoal in these deposits which has suggested fire—adaptation as an early selective pressure. ‘Maria T. Haworth is completing an undergraduate project in collaboration with Dr. Ipes and Er. Rothwell, investigating a fossil conifer cone that has well— preserved cotyledonary embryos and gametophyte tissue in its seeds. These features represent a critical step in the evolution of seed dormancy and the introduction of physiological delay sequences between pollination and fertilization and seed germination in gymnosperms and angiosperms. GAYLE E. MUENCHOW: Er. enchow’s research is in the general area of evolutionary transitions from one breeding system to another in flowering plants. In the past 12 months, she and undergraduate Marcella C’ebus researched the subject of the evolutionary transition from distyly to ctioecy. If pollen simply ceases to move from the low anthers of pins to the low stigmas of thrums, a distylous population becomes ftmctionally dioecious. The suggestions have been made in the literature that if distylous plants lost their long— tongue pollinator, the plants would become functionally dioecious and that morphological dioecy would evolve thereafter by loss of unused parts, with the pins becoming the pistillate plants and the thrums becoming the staminate plants. This was investigated in two ways. Grebus completed a computer simulation of the spread of male sterility and female sterility mutations in a distylous population that was suffering various degrees of loss of the long tongue
GENE K. RAPES: Dr. Mapes is continuing her investigations of the biology, ecology and systematics of the earliest conifers, with particular interest in certain Middle and Upper Pennsylvanian shale and limestone deposits in midcontinental North
pollinator. This showed that the spread of these alleles is not likely to occur except under the most restrictive conditions, casting some doubt on the applicability of the hypothesis. Muenchow surveyed all of the 1aowri cases of this evolutionary transition and found that in only one case was there any particular reason to think that the thrums did in fact become staminate and the pins pistillate. They concluded that this deceptively simple hypothesis is not in fact particularly supportable. s-ian Gara finished his masters work this Spring (.iarter. F has worked on cleistogamy in the previously unstudied species, Trioclanis perfoliata (Campanulaceae). His research had two goals——to learn enough about the phenology, germinability and growth requirements of the species to make it practical for in—depth research and to begin to look for ecological and physiological situations that iuld explain the possible adaptive significance of this breeding system. He learned that the open flowers are more likely to fail to set seed the later they bloom, that the period of reproduction comes to an abrupt, environmentally induced halt (due to drought), and that there is little difference between the seeds of open and closed flowers in regard to germinability and requirements for germination. ian will earn his teaching certificate in Chic this year and expects to teach science at the post— elementary level. Thulisiwe Ndelu joined her lab from South Africa this year. e began her research this spring cr1 a field based survey of native herbs and shrubs. Her data will allow her to look for patterns in floral longevity, color, and size, length of time from flowering to fruiting, percent fruit set under natural conditions and whether this is
limited by inadequate pollination. Across species patterns can give a sense of the constraints the environment places on flowers and what they must do to become successful. Leslie Dybiec is doing an undergraduate project, following the fate of several hundred Viola papilionacea buds! flowers/fruits. They are putting together a life— history of these reproductive structures, expecting this to elucidate such questions as why they bloom when they do, why they have the numbers of flowers that they do, and why they switch between open arid closed flowers. Leslie will be graduating this June and wiil continue her work in horticulture at Virginia Polytechnique Institute. Dr. ienchow presented a paper at the Botanical Society of America meetings this past summer in Amherst, Massachusetts, and presented seminars at Bowling Green State University and Denison University in Chio.
Gar W. Rothwell: Er. Rothwell currently is coordinating planning for new Botany facilities at aiio University. Although the anticipated facilities will not be available for several years, this activity provides a focus for considering long—term departmental development. In the area of curriculum, Er. Rothwell recently has developed a graduate course in Botanical Photography, arid is in the process of reformulating the teaching of vascular plant morphology to encompass developmental phenomena within the systematic and evolutionary framework. Dr. Rothwell’s research interests continue to center on the origin and early evolution of seed plants, but recently have also included the early evolution of ferns. The primitive seed plant work is in the second year of 6
N.S.F. funding, and is progressing in collaboration with Dr. David C. Wight. A relatively new Ph.D. student from the Peoples Republic of China, i Li, has begun his graduate research on some of the most ancient remains. Janelle Pryor also is studying seed plants, and has initiated her Pn.D. research on the paleoecology of fossilizea coal swamps. Ers. Rothwell and Wight will be presenting the results of the work at an International Botanical Congress in West Berlin this July. They also plan to collect additional material on the east coast of southern Scotland in August. An additional postdoctoral fellow, Dr. Richard Bateman of the University of London, is planning to join the laboratory in ODtober to study the primitive seed plants. The work on ancient ferns is being carried out in conjunction with Dr. W.H. Wagner of the University of Michigan and Er. Thth Stockey of the University of Alberta, and additional results are being obtained by continuing Ph.D. student, ry Louise “Cookie 11 Trivett. The newest member of the laboratory, Dr. Bing—cheng Feng, wnd recently completed his Ph.D. at the University of Michigan, is actively engaged in the fern work. Trivett will be reporting her work at the Berlin Botanical Congress in July, and all of the members of the laboratory will be presenting the results of their studies at the Botanical Society of America meetings at Columbus, Ohio this August.
organization committee of the Association of Educational and Research Greenhouse Chrators, Chairman of the Interim Executive Committee, and chaired the November meeting. He also chaired the constitution and corporation committee, and wrote the constitution and corporate papers at the University of Illinois in July 1986. He has been elected interim president and chairman of the executive committee in charge of the first general meetings, to be held at Southern illinois University, Carbondale, this June, 1987. In addition, he received a plaque from the International Plant Propagation Society honoring his contributions to the industry in June, 1986. ALLAN SHOWALTER: Research in Er. Showalter’s lab involves two classes of plant hydroxyproline— rich glycoproteins (HRGP5), the cell wall HRGP5 and the solanaceous lectins. The cell wall HRGPs constitute an important structural component of plant cell walls and also accumulate in response to wounding and pathogen infection as an apparent defense mechanism. The overall goal of his current cell wall HRGP research is two—fold: to elucidate the structure of both constitutive and wound—regulated cell wall HRGP genes and to investigate the wound—regulated expression of these genes. As an initial approach to ftlfilling these goals, he has constructed two eDNA (complementary DNA) libraries from unwounded and wounded tomato stem tissue and isolated a number of different cell wall HRGP cDNA clones. Using these eDNA clones as molecular probes, genoinic DNA is also being isolated and subjected to DNA sequence analysis, and the resulting information used to elucidate the complete genomic organization of these cell wall HRGP genes including the regulatory sequences from the different cell

wall HRGP genes. BDth the eDNA and genomic clones encoding the cell wall HRGPs are also being used as molecular probes in RNA blotting experiments to monitor HRGP mRNA levels in response to wounding and pathogen infection. The solanaceous lectins have been found to accumulate in plants in response to pathogen infection and are thought to play a role in plant defense by agglutinating potential pathogens. The potato lectin is the most thoroughly studied of the solanecous lectins and may be an evolutionary relative of the cell wall HRGPs. He now plans to isolate cDNA clones encoding the potato lectin in order to elucidate its sequence and to investigate the infection—regulated expression of the potato lectin gene. Jin Zhou is a first year graduate student working in his lab on a project yet to be determined. Dominique Rurneau has also joined him in his research as a post doctoral fellow. She is from France and is irking on isolation, characterization and expression of constitutive and wound—regulated HRGP in tomato. Dr. Showalter has been active in the Molecular and Cell Biology Program this year, serving as chairman of the curriculum committee and on the search committee for a new molecular biologist in chemistry. He was invited to participate in a symposium on plant genes of economic interest at the University of Wisconsin in Cotober 1986, presenting a paper “Hydroxyproline-. rich glycoprotein genes and their expression under stress conditions”. This summer he has been invited to speak to the Plant Molecular Biology Gordon Conference on “Hydroxyproline—rich glycoproteins”. He has also presented seminars to the Department of Chemistry, New Mexico State University and to the Department of &tany, Chio State
University on his research. writes that “assuming a pending grant is ftnc1ed, I would be interested in receiving letters of application from individuals with molecular biology experience for a postdoctoral position in my laboratory studying stress— regulated expression of plant hydroxyprol ine-.rich gl ycoprotein genes. I am also currently advertising for a molecular biology laboratory technician (with previous molecular biology experience) .“
IRWIN A. UNGAR: Dr. Ungar is currently studying the factors influencing the establishment of SperguJ.aria marina populations. Two approaches are being used to ascertain data. Firstly, the effects of temperature and salinity on seed germination of monthly seed collections are being studied in the laboratory. Seed dormancy apparently varies with the season of seed maturation. Factors alleviating dormancy are being determined. Secondly, seed demography is being monitored from field collections to determine whether or not a consistent seed bank is formed and precisely what proportion of seeds can remain dormant during the primary germination period. Four graduate students are currently carrying out their dissertation and thesis research in his lab. Kern Badger, Don Drake and Marlis Rahman are studying the effects of salinity gradients and competition on the growth and distribution of halophytes. Jim Nellessen is determining the factors that influence the growth and stress tolerance of populations of Andropogon virginicus in old field and spoil bank habitats. Rachel LaPoint, a MSES graduate student, is currently working on her thesis. Several grants have been obtained for the lab. Jim Nellessen 8
and Kem Badger have received John Hc’uk research awards. Kern Badger and Ingrid Chorba also received funding from Sigma Xi to support their activities. tv’. Ungar presented a paper at the IV International Congress of Ecology at Syracuse, New York, on “Effects of seed maturation time on the temperature requirements for germination and salinity tolerance of Spergularia marina seeds.”
