Os11g0267000

The rice Os11g0267000 was reported as OsGUN4 (genomes uncoupled 4) in 2014 by researchers from China.

Annotated Information

Gene Symbol

• Os11g0267000 <=> OsGUN4

Function

• For easy testing and to increase varietal purity, a xantha mutation (xnt), which turns plants yellow and makes them visually distinguishable from normal green rice, has been generated and bred into male sterile lines for hybrid rice production.
• we have identified an epi-allele of OsGUN4 as the causal gene of the xantha marker trait and revealed that enhanced methylation in its promoter down-regulated its expression in rice.

Expression

• The expression of OsGUN4 was significantly reduced in HYB compared with LTB in terms of both transcript abundance (0.2 % that of LTB) and expressed protein level (barely detectable in HYB but greater than the heat shock protein reference in LTB).
