Os08g0266700

The rice Os08g0266700 was reported as OsRAD21-3 in 2007 by researchers from the China.

Annotated Information

Gene Symbol

• Os08g0266700 <=> OsRAD21-3

Function

• OsRad21-3 is an orthologue of yeast Rad21. OsRAD21-3 transcript and protein accumulated preferentially in flowers, with low levels in vegetative tissues.

Expression

• The four OsRAD21 genes in the rice genome, only OsRAD21-3 was expressed in pollen grains.

Mutant

• OsRAD21-3-deficient RNAi lines showed arrested pollen mitosis, aberrant pollen chromosome segregation and aborted pollen grains, which led to disrupted pollen viability.However, male meiosis in these RNAi lines did not appear to be severely disrupted, which suggests that the main involvement of OsRAD21-3 is in post-meiotic pollen development by affecting pollen mitosis.
