Science Tech (Seed Storage) Vacant ISU Positions: None Appendix Figure 1 illustrates the organization of the NCRPIS staff and their roles. Management of Federal and ISU Student Temporary Employees: USDA-ARS resources provided for 19 student part-time temporary positions in FY 2016, primarily via the Research Support Agreement with Iowa State University, and a Ph.D. student (plant breeding and genetics, GEM funds). NC7 resources provided for an addition 0.5 student FTE. The ORISE and other temporary positions support curatorial activities including regeneration, seed processing, viability testing, farm and facilities operations, IT support, and the GEM Project. Students were interviewed and selected by ISU Program Manager Fred Engstrom. Marci Bushman and Heather Kearney managed the administrative aspects of all student hires, with support and guidance from Ames ARS & APHIS HR Specialists Lindsay Evans and Sireena Foley, and ARS Admin. Officers Carol Moran, and Candace Weuve. Budget: We appreciate the support of the Agricultural Experiment Stations of the North Central Region, which have maintained their annual support and continued to provide $522,980 in Hatch funds. These funds support the salaries of our nine ISU staff members, their professional travel, and some expenses. In addition, Iowa State University’s Agricultural Experiment Station provides support valued at over $400,000 annually that supports infrastructure, administration, and benefits for current NCRPIS-ISU staff members and retirees. 2 We are grateful that Hatch funding resources were maintained throughout the difficult sequestration period, and hope they continue to be stable or increase in the future. Currently, about 96% of Hatch NC7 funds are devoted to the wages and salaries of the nine permanent ISU employees. In the near future we will be unable to provide incremental salary increases due to Hatch funding constraints. If ISU wage increases of 1.5% are granted in FY18, this figure climbs to 97%; if an additional 1% increase is granted in FY19 barring personnel changes. This limits professional meeting travel, technical training, and temporary student hiring with ISU resources. FY2018 USDA-ARS funding was essentially the same as final FY2014 funding, minus a one percent assessment for ‘Big Data.’ The PI CRIS was funded at $2.38M (net to location) and the GEM CRIS at $1.2M. Student hiring for summer 2018 was challenging, despite raising our starting wage for ISU students by almost $2/hour to $12/hour, and we were not quite able to fulfill the need for 25 summer FTE, but much better than in 2017. We attribute this to both the requirement for all agriculture students to complete internships, and the growing disparity in what we can offer for wages versus other hiring opportunities. F. Engstrom advertised positions more widely across ISU colleges, and the students that did apply were excellent. Any reductions in funding will force reduction in student hiring, necessary for executing our genebank’s mission. Like many other research units, our ability to cover all aspects of our mission is challenged. Our personnel strive to cover all functions and serve the collections entrusted to us and our stakeholders to the best of our ability. Given the high turnover since 2014, a great deal of time and attention has been paid to recruitment and hiring activities,

    Understanding the Weedy Chenopodium Complex in the North Central States

    UNDERSTANDING THE WEEDY CHENOPODIUM COMPLEX IN THE NORTH CENTRAL STATES BY SUKHVINDER SINGH DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Crop Sciences in the Graduate College of the University of Illinois at Urbana-Champaign, 2010 Urbana, Illinois Doctoral Committee: Professor Patrick J. Tranel, Chair Associate Professor Aaron G. Hager Associate Professor Geoffrey A. Levin Assistant Professor Matthew E. Hudson ABSTRACT The genus Chenopodium consists of several important weed species, including Chenopodium album, C. berlandieri, C. strictum, and C. ficifolium. All of these species share similar vegetative morphology and high phenotypic plasticity, which makes it difficult to correctly identify these species. All of these weedy Chenopodium species have developed resistance to one or more classes of herbicides. An experiment was conducted to determine if there is variability in response of Chenopodium species present in the North Central states to glyphosate. Our results indicate variable responses within and among the Chenopodium species. Species such as C. berlandieri and C. ficifolium had higher levels of tolerance to glyphosate than did various accessions of C. album. In another experiment, 33 populations of Chenopodium sampled across six North Central states were screened with glyphosate. The results showed variable responses to glyphosate within and among the Chenopodium populations. In general, the Chenopodium populations from Iowa were more tolerant, but some biotypes from North Dakota, Indiana and Kansas also had significantly high tolerance to glyphosate. Given there are species other than C. album that have high tolerance to glyphosate, and there are Chenopodium populations across the North Central states that showed tolerance to glyphosate, one intriguing question was to whether the Chenopodium populations were either biotypes of C.

A PHYLOGENY OF LEGUMES (LEGUMINOSAE) BASED ON ANALYSIS OF THE PLASTID MATK GENE RESOLVES MANY WELL-SUPPORTED SUBCLADES WITHIN THE FAMILY1 MARTIN F. W OJCIECHOWSKI,2,5 MATT LAVIN,3 AND MICHAEL J. SANDERSON4 2School of Life Sciences, Arizona State University, Tempe, Arizona 85287-4501 USA; 3Department of Plant Sciences, Montana State University, Bozeman, Montana 59717 USA; and 4Section of Evolution and Ecology, University of California, Davis, California 95616 USA Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly of subfamily Papilionoideae and at least seven major subclades are well-supported by bootstrap and Bayesian credibility values. These subclades are informally recognized as the Cladrastis clade, genistoid sensu lato, dalbergioid sensu lato, mirbelioid, millettioid, and robinioid clades, and the inverted-repeat-lacking clade (IRLC). The genistoid clade is expanded to include genera such as Poecilanthe, Cyclolobium, Bowdichia, and Diplotropis and thus contains the vast majority of papilionoids known to produce quinolizidine alkaloids. The dalbergioid clade is expanded to include the tribe Amorpheae. The mirbelioids include the tribes Bossiaeeae and Mirbelieae, with Hypocalypteae as its sister group. The millettioids comprise two major subclades that roughly correspond to the tribes Millettieae and Phaseoleae and represent the only major papilionoid clade marked by a macromorphological apomorphy, pseu- doracemose in¯orescences.

    Fruit and Seed Anatomy of Chenopodium and Related Genera (Chenopodioideae, Chenopodiaceae/ Amaranthaceae): Implications for Evolution and Taxonomy Alexander P. Sukhorukov1,2*, Mingli Zhang1,3 1 Key Laboratory of Biogeography and Bioresource in Arid Land, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi, Xinjiang, China, 2 Department of Higher Plants, Biological Faculty, Moscow Lomonosov State University, Moscow, Russia, 3 Institute of Botany, Chinese Academy of Sciences, Beijing, China Abstract A comparative carpological study of 96 species of all clades formerly considered as the tribe Chenopodieae has been conducted for the first time. The results show important differences in the anatomical structure of the pericarp and seed coat between representatives of terminal clades including Chenopodium s.str.+Chenopodiastrum and the recently recognized genera Blitum, Oxybasis and Dysphania. Within Chenopodium the most significant changes in fruit and seed structure are found in members of C. sect. Skottsbergia. The genera Rhagodia and Einadia differ insignificantly from Chenopodium. The evolution of heterospermy in Chenopodium is discussed. Almost all representatives of the tribe Dysphanieae are clearly separated from other Chenopodioideae on the basis of a diverse set of characteristics, including the small dimensions of the fruits (especially in Australian taxa), their subglobose shape (excl. Teloxys and Suckleya), and peculiarities of the pericarp indumentum. The set of fruit and seed characters evolved within the subfamily Chenopodioideae is described. A recent phylogenetic hypothesis is employed to examine the evolution of three (out of a total of 21) characters, namely seed color, testa-cell protoplast characteristics and embryo orientation.
