Abstract

The ubiquitous family of 14-3-3 proteins functions as regulators in a variety of
physiological processes. Eight rice 14-3-3 genes, designated OsGF14a through h,
were identified from an exhaustive search of the genome database. Comparisons of
deduced amino acid sequences reveal a high degree of identity among members of
the OsGF14 family and reported Arabidopsis 14-3-3 proteins. A phylogenetic study
indicates that OsGF14s contain both epsilon and non-epsilon forms, which is also
confirmed by a structural analysis of OsGF14 genes. Furthermore, transcripts of
OsGF14b, OsGF14c, OsGF14d, OsGF14e, OsGF14f and OsGF14g were detected in rice
tissues. Their different expression patterns, the different effects of
environmental stresses and plant hormones on their transcription levels, and the
different complementary phenotypes in yeast 14-3-3 mutants not only indicates
that OsGF14s are responsive to various stress conditions and regulated by
multiple signaling pathways, but also suggests that functional similarity and
diversity coexist among the members of OsGF14 family.
