Molecular diversity and relationships among Elymus trachycaulus, E. subsecundus, E. virescens, E. violaceus, and E. hyperarcticus (Poaceae: Triticeae) as determined by amplified fragment length polymorphism.

Abstract excerpt

Morphological similarity among E. trachycaulus, E. virescens, E. violaceus, and E. hyperarcticus has often been noted. Taxonomists have tried to discriminate among these taxa using morphological characters and a number of different relationships among them have been suggested. However, the genetic relationships among these taxa are still unknown. AFLP analysis was used to characterize the molecular diversity of...
