Diversification of the plant-specific hybrid glycine-rich protein (HyGRP) genes in cereals.

ABSTRACT: Plant-specific hybrid proline- or glycine-rich proteins (HyP/GRPs) are involved in diverse gene functions including plant development and responses to biotic and abiotic stresses. The quantitative trait locus, qLTG3-1, enhances seed germination in rice under low-temperature conditions and encodes a member with a glycine-rich motif of the HyP/GRP family. The function of this gene may be related to the weakening of tissue covering the embryo during seed germination. In the present study, the diversification of the HyP/GRP gene family was elucidated in rice based on phylogenetic relationships and gene expression levels. At least 21 members of the HyP/GRP family have been identified in the rice genome and clustered in five regions on four chromosomes by tandem and chromosomal duplications. Of
