Os02g0595900

The rice Os02g0595900 was reported as OsNAR2.1 in 2005 by researchers from the USA.

Annotated Information

Gene Symbol

• Os02g0595900<=> OsNAR2.1

Function

• OsNAR2.1 plays a key role in enabling the plant to cope with variable nitrate supply.

Expression

• OsNAR2.1 was mainly expressed in roots and induced by nitrate and suppressed by ammonium and some amino acids.

Mutant

• Knockdown of OsNAR2.1 by RNA interference synchronously suppressed expression of OsNRT2.1, OsNRT2.2 and OsNRT2.3a in the osnar2.1mutants. Both high- and low-affinity nitrate transports were greatly impaired by OsNAR2.1 knockdown.
