The rice Os01g0273800 was reported as OsYUC9 in 2012 [1] by researchers from Australia.

Annotated Information

Gene Symbol

  • Os01g0273800 <=> OsYUCCA9, OsYUC9, YUC9

Function

  • IAA production in developing rice grains is controlled via expression of OsTAR1, OsYUC9, OsYUC11 and that IAA may be important during starch deposition in addition to its previously suggested role early in grain development.

Expression

  • OsYUC9 was expressed in endosperm.

Evolution

  • Phylogenetic analysis indicated that OsYUC11 and AtYUC10 belong to a separate clade of YUCCAs, which do not have orthologues outside the Angiosperms. This clade may have evolved with a specific role in endosperm.
