The rice Os03g0106300 was reported as pair1 in 2004 [1] by researchers from the Japan.

Annotated Information

Gene Symbol

  • Os03g0106300 <=> pair1


Function

  • The PAIR1 gene encodes a 492–amino acid protein, which contains putative coiled-coil motifs in the middle, two basic regions at both termini, and a potential nuclear localization signal at the C terminus.
  • The PAIR1 protein plays an essential role in establishment of homologous chromosome pairing in rice meiosis.


Expression

  • Expression of the PAIR1 gene was detected in the early stages of flower development, in which the majority of the sporocytes had not entered meiosis.


Evolution

  • The pair1mutation, tagged by the endogenous retrotransposon Tos17, exhibited meiosis-specific defects and resulted in complete sterility in male and female gametes.
