Abstract

Flowering time is a key component of plant adaptation with major impacts on yield and quality. Understanding flowers in cereals is therefore important for the development of improved varieties and sustainable agricultural systems. We have identified three early maturity (eam) mutants of barley that lack the normal circadian regulation of genes implicated in controlling flowering. This provides a model for their early flowering phenotype and adaptation to short growing seasons. Comparison of gene expression in eam mutant and wild type plants provides a novel opportunity to identify key genes governing the transition to flowering in temperate cereals. The work will analyse barley homologues of genes controlling the transition to flowering in Arabidopsis and use barley microarrays to identify additional genes that are up or down regulated at key developmental stages.
