Transcriptional responses of winter barley to cold indicate nucleosome remodelling as a specific feature of crown tissues
2011
Abstract
We report a series of microarray-based compar- isons of gene expression in the leaf and crown of the winter barley cultivar Luxor, following the exposure of young plants to various periods of low (above and below zero) temperatures. A transcriptomic analysis identified genes which were either expressed in both the leaf and crown, or specifically in one or the other.
Among the former were genes responsible for calcium and abscisic acid signalling, polyamine synthesis, late embryogenesis abundant proteins and dehydrins.
