Research Project:

Patterns of Gene Expression and Silencing in North American Elymus (Triticeae: Poaceae) Allotetraploids

Elymus glaucus

Elymus L., is the largest and most widely distributed genus in the wheat tribe Triticeae (Poaceae). This genus is an exclusively allopolyploid group, characterized by huge morphological variation within and between species. Cytologically, five basic genomes, designated S, H, Y, P and W are found within the genus, in a variety of combinations. Cytogenetic and phylogenetic data confirms that nearly all North American species contain a maternal (S) genome from Pseudoroegnaria and paternal (H) genome from Hordeum, in a tetraploid combination StStHH.

My research will focus on investigating patterns of gene expression and gene silencing in natural North American populations of Elymus with the following objectives: (1) examine the relative expression and silencing of selected genes in North American Elymus species in different organ types of each individual plant, and during different developmental stages; (2) examine gene expression and silencing patterns in multiple independently created synthetic allotetraploid lines of Elymus and compare the results with the observed patterns of gene silencing in natural populations; (3) compare overall patterns of gene expression and silencing of North American samples and those from Europe with the same genomic composition (e.g. StStHH).
