Relationship between homoeologous regulatory and structural genes in allopolyploid genome - a case study in bread wheat.

ABSTRACT:

Background

The patterns of expression of homoeologous genes in hexaploid bread wheat have been intensively studied in recent years, but the interaction between structural genes and their homoeologous regulatory genes remained unclear. The question was as to whether, in an allopolyploid, this interaction is genome-specific, or whether regulation cuts across genomes. The aim of the present study was cloning, sequence analysis, mapping and expression analysis of F3H (flavanone 3-hydroxylase - one of the key enzymes in the plant flavonoid biosynthesis pathway) homoeologues in bread wheat and study of the interaction between F3H and their regulatory genes homoeologues - Rc (red coleoptiles).

Results

PCR-based cloning of F3H sequences from hexaploid bread wheat (Triticum aestivum
