متن کاملCharacterisation and Analysis of the Aegilops sharonensis Transcriptome, a Wild Relative of Wheat in the Sitopsis Section
Aegilops sharonensis Eig (Sharon goatgrass) is a wild diploid relative of wheat within the Sitopsis section of Aegilops. This species represents an untapped reservoir of genetic diversity for traits of agronomic importance, especially as a source of novel disease resistance. To gain a foothold in this genetic resource, we sequenced the cDNA from leaf tissue of two geographically distinct Ae. sh...
متن کاملComparative Mapping and Targeted-Capture Sequencing of the Gametocidal Loci in Aegilops sharonensis.
Gametocidal (Gc) chromosomes or elements in species such as Eig are preferentially transmitted to the next generation through both the male and female gametes when introduced into wheat ( L.). Furthermore, any genes, such as genes that control agronomically important traits, showing complete linkage with Gc elements, are also transmitted preferentially to the next generation without the need fo...
متن کاملWheat Transformation: a Needed Tool for Wheat Genetics and Germplasm Improvement
Fusarium head blight (FHB) is a major disease of wheat in the north central and eastern United States that affects both grain yield and end-use quality. It is generally agreed that the most cost effective way of preventing this disease would be through the release of FHB resistant cultivars. A major limitation to developing FHB resistant cultivars is the limited availability of resistant germpl...
متن کاملOrigin and expansion of the allotetraploid Aegilops geniculata, a wild relative of wheat.
*This study reconstructs the phylogeography of Aegilops geniculata, an allotetraploid relative of wheat, to discuss the impact of past climate changes and recent human activities (e.g. the early expansion of agriculture) on the genetic diversity of ruderal plant species. *We combined chloroplast DNA (cpDNA) sequencing, analysed using statistical parsimony network, with nonhierarchical K-means c...
