The rice gene Os06g0677000 was reported as dep3 in 2011[1] by researchers from Korea, China and USA.

Annotated Information

Gene Symbol

  • Os06g0677000 <=> dep3, OspPLAIIIdelta, pPLAIIIdelta

Function

  • The DEP3 gene was identified as the candidate via a map-based cloning approach and was predicted to encode a patatin-like phospholipase A2 (PLA2) superfamily domain-containing protein.
  • The patatin-like PLA2 might play a significant role in the formation of vascular bundles, and that the dep3 mutant may provide another EP resource for rice breeding programs.

Mutation

  • The panicle of the dep3 mutant remained erect from flowering to full maturation, whereas the panicle of the wild type plant began to droop after flowering. The dep3 mutation also regulated other panicle characteristics, including panicle length, grain shape and grain number per panicle. Anatomical observations revealed that the dep3 mutant had more small vascular bundles and a thicker culm than wild type plants, explaining the EP phenotype.
