(RAPHANUS RAPHANISTRUM) Heather F. Sahli

However, genetic drift, particularly due to founder effects, will also commonly result in differentiation in colonizing species. To test whether selection has contributed to trait divergence, we compared differentiation at eight microsatellite loci (measured as FST) to differentiation of quantitative floral and phenological traits (measured as QST) of wild radish (Raphanus raphanistrum) across populations from three continents. We sampled eight populations: seven naturalized populations and one from its native range. By comparing estimates of QST and FST, we found that petal size was the only floral trait that may have diverged more than expected due to drift alone, but inflorescence height, flowering time and rosette formation have greatly diverged between the native and non-native populations. -

Landscape dynamics determine the small-scale genetic structure of an endangered dune slack plant species. Journal of Coastal Research, 28(4), 780–786. West Palm Beach (Florida), ISSN 0749-0208. Understanding the processes that determine genetic variation within landscapes is a crucial factor for successful management of threatened plant species that are sensitive to both environmental and genetic bottlenecks. While current insights point to the importance of historical landscape processes for the genetic structure of populations at large spatial scales, their relevance at small spatial scales has been largely neglected. In this context, coastal dunes are a typical example of dynamic and geologically young landscapes in which current and historical sand drift may have strong impacts on the spatial dynamics of a large number of plant species. One of these is the endangered plant species Parnassia palustris, typically inhabiting dune slacks formed by recent sand displacements in parabolic dune landscapes. -

Determination of Genetic Diversity of Some Species of Brassicaceae Using SDS-PAGE of Seed Protein and ISSR Markers
20 Egypt. J. Bot., Vol. 55, No.2 pp. 307- 318 (2015) Determination of Genetic Diversity of Some Species of Brassicaceae Using SDS-PAGE of Seed Protein and ISSR Markers Nelly M. George Botany Department, Faculty of Science, Zagazig University, 44519 Egypt VALUATION of genetic diversity among 10 species of E Brassicaceae have been performed based on variations in seed protein electrophoretic patterns as revealed by SDS-PAGE and ISSR analyses, separately and in combination. The maximum genetic similarity was observed between Brassica nigra and B. rapa, while the lowest genetic similarity was observed between B. nigra and Sisymbrium irrio. Cluster analysis generated a dendrogram that separated the studied taxa in two main clusters; the five species of tribe Brassiceae were grouped close to each other in one cluster with Sisymbrium irrio. The remaining studied species; Capsella bursa- pastoris, Erysimum cheiranthoides, Mathiola longipetale and Thlaspi arvense, were grouped in a second cluster. Keywords: Brassicaceae, SDS-PAGE, ISSR, Genetic diversity. The Brassicaceae (Cruciferae or mustard family) includes several crop plants grown worldwide, some of which have been cultivated since prehistoric times. Various species are grown for oil, mustard condiment, fodder and forage for animals, or as vegetables (Crisp, 1976 and Simmonds, 1986). Several classification systems were proposed from the early 19th to the mid 20th century. According to these systems, the Brassicaceae divided into anywhere from 4 to 19 tribes and 20 to 30 sub-tribes (Schulz, 1936 and Janchen, 1942). Mark et al. (2006) suggested that Brassicaceae includes two important model systems; the first included the Arabidopsis thaliana (L.) Heynh. -

Erysimum Cheiranthoides (Brassicaceae) Reduces Total Cardenolide Abundance but Increases Resistance to Insect Herbivores

Younkin1 & Amy P. Hastings3 & Martin L. Alani1 & Anurag A. Agrawal3 & Georg Jander1 Received: 26 April 2020 /Revised: 6 October 2020 /Accepted: 9 October 2020 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Erysimum cheiranthoides L (Brassicaceae; wormseed wallflower) accumulates not only glucosinolates, which are characteristic of the Brassicaceae, but also abundant and diverse cardenolides. These steroid toxins, primarily glycosylated forms of digitoxi- genin, cannogenol, and strophanthidin, inhibit the function of essential Na+/K+-ATPases in animal cells. We screened a popu- lation of 659 ethylmethanesulfonate-mutagenized E. cheiranthoides plants to identify isolates with altered cardenolide profiles. One mutant line exhibited 66% lower cardenolide content, resulting from greatly decreased cannogenol and strophanthidin glycosides, partially compensated for by increases in digitoxigenin glycosides. This phenotype was likely caused by a single- locus recessive mutation, as evidenced by a wildtype phenotype of F1 plants from a backcross, a 3:1 wildtype:mutant segregation in the F2 generation, and genetic mapping of the altered cardenolide phenotype to one position in the genome. The mutation created a more even cardenolide distribution, decreased the average cardenolide polarity, but did not impact most glucosinolates. Growth of generalist herbivores from two feeding guilds, Myzus persicae Sulzer (Hemiptera: Aphididae; green peach aphid) and Trichoplusia ni Hübner (Lepidoptera: Noctuidae; cabbage looper), was decreased on the mutant line compared to wildtype. -
