  • a The number of exons (E) and introns (I) deduced either from comparison with cDNAs or from prediction programs.

  • b The number of amino acid residues.

  • c For each barley gene, orthologs found on rice chromosome 1 are indicated with the names given in the GenBank annotation.

  • d Homologs to the 10 barley genes identified in the rice databases are indicated with their chromosomal location as annotated in the database.

  • e Homology was found with rice genes other than the OsHGA orthologs but was limited to the very conserved C-terminal region of the HGA genes.
