Structural and functional divergence of the Mpc1 genes in wheat and barley.

ABSTRACT:

Background

The members of the Triticeae tribe are characterised by the presence of orthologous and homoeologous gene copies regulating flavonoid biosynthesis. Among transcription factors constituting a regulatory MBW complex, the greatest contribution to the regulation of flavonoid biosynthetic pathway is invested by R2R3-Myb-type TFs. Differently expressed R2R3-Myb copies activate the synthesis of various classes of flavonoid compounds in different plant tissues. The aim of this research was the identification, comparison and analysis of full-length sequences of the duplicated R2R3-Myb Mpc1 (Myb protein c1) gene copies in barley and wheat genomes.

Results

The Mpc1 genes were identified in homoeologous group 4 and 7 chromosomes: a total of 3 copies in barley (Hordeum vulgare
