Figure 2. Analysis of the rice GUN4 gene and its mutations. a Schematic diagram of the OsGUN4 locus.[1].

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).
