• Information
  • Symbol: OsRAD21-3
  • MSU: LOC_Os08g16610
  • RAPdb: Os08g0266700
• Publication
  • OsRAD21-3, an orthologue of yeast RAD21, is required for pollen development in Oryza sativa, 2007, Plant J.
• Genbank accession number
  • AK101268
• Key message
  • 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
  • Furthermore, of the four OsRAD21 genes in the rice genome, only OsRAD21-3 was expressed in pollen grains
  • OsRAD21-3, an orthologue of yeast RAD21, is required for pollen development in Oryza sativa
  • OsRAD21-3 transcript and protein accumulated preferentially in flowers, with low levels in vegetative tissues
