Comparative genomic analysis and expression of the APETALA2-like genes from barley, wheat, and barley-wheat amphiploids.

ABSTRACT:

Background

The APETALA2-like genes form a large multi-gene family of transcription factors which play an important role during the plant life cycle, being key regulators of many developmental processes. Many studies in Arabidopsis have revealed that the APETALA2 (AP2) gene is implicated in the establishment of floral meristem and floral organ identity as well as temporal and spatial regulation of flower homeotic gene expression.

Results

In this work, we have cloned and characterised the AP2-like gene from accessions of Hordeum chilense and Hordeum vulgare, wild and domesticated barley, respectively, and compared with other AP2 homoeologous genes, including the Q gene in wheat. The Hordeum AP2-like genes contain two plant-specific DNA binding motifs called AP2 domains, as doe
