Zn-Deficiency Responsive Transcripts in Agrostis Species Revealed by mRNA Differential Display

摘要

Grass family has a particular importance as rice, wheat, and maize constitutes the major portion of diet not only for humans but also for domestic animals. Moreover, grasses form a significant part of the urban and suburban landscape all over the world, covering approximately 20 % of the earth's land surface (Shantz 1954; Kellogg 2001).Agrostis genus of the Poaceae family consists of more than 200 species. Three bentgrasses, namely Creeping bentgrass (Agrostis stoloniferd), Colonial bentgrass (Agrostis capillaris), and Velvet bentgrass (Agrostis canina), are the most widely used members of the genus, especially in athletic fields and golf courses (Hitchcock 1935; Budak et al. 2006). Among these three, creeping bentgrass is the most commercially important bentgrass used especially in golf course due its fine leaves and tolerance to lowcutting heights (Belanger et al. 2003).
