Abstract
Photoperiod (Ppd) response genes on the short arms of the group 2 chromosomes are the major determinants of flowering in response to day length in wheat and barley, and one of the major determinants of adaptation. Ppd alleles therefore have major impacts on yield and grain quality, but their deployment in breeding programmes is hampered by a lack of knowledge of allelic diversity and gene function. Comparative mapping shows that the wheat and barley gene are in colinear map positions, and the cloning of one should therefore give access to all. The proposal is to clone the Ppd-H1 gene from barley which has been mapped to a 1.4cM interval colinear to a region of rice chromosome 7. The proposal exploits recently developed genetic and genomic tools including rice genomic sequence, large insert (BAC) libraries of cereals, cereal EST databases and cereal transformation.
