Os01g0645400

The rice Os01g0645400 was reported as OsYUCCA1 in 2007 by researchers from the China.

Annotated Information

Gene Symbol

• Os01g0645400 <=> OsYUCCA1

Function

• The rice enzyme OsYUCCA1 in IAA biosynthesis via the tryptophan-dependent pathway.

Expression

• OsYUCCA1 was expressed in almost all of the organs tested, but its expression was restricted to discrete areas, including the tips of leaves, roots, and vascular tissues, where it overlapped with expression of a b-glucuronidase reporter gene controlled by the auxin-responsive DR5 promoter.

Mutant

• Plants overexpressing OsYUCCA1 exhibited increased IAA levels and characteristic auxin overproduction phenotypes, whereas plants expressing antisense OsYUCCA1 cDNA displayed defects that are similar to those of rice auxininsensitive mutants.
