DNA markers and gene expression polymorphisms
associated with growth habit quantitative trait loci in Leymus
wildryes
Kaur, Parminder. 2007. DNA markers and gene expression polymorphisms associated with growth habit quantitative trait loci in Leymus wildryes. Logan, UT: Utah State University. 128 p. Dissertation.
The genus Leymus includes about 30 long-lived perennial Triticeae grasses distributed throughout cold and/or semiarid regions of Americas, Europe, and Asia. Leymus cinereus and L. triticoides display divergent growth habit adaptations to different microenvironments in western North America. L. cinereus, a tall caespitose bunch grass, is commonly found near mountain and foothill waterways. L. triticoides, a relatively short rhizomatous grass, is restricted along stream banks or saline wetlands. Subterranean tiller and rhizome buds appear similar but display different responses to gravity and other cues governing branch angle and overall growth habit.
