Gene Details:

Functional Descriptions:

  • Rice plants with loss-of-function of OsSPO11-1 have no apparent growth defects during vegetative development, but homologous chromosome pairing and recombination are significantly obstructed.
  • Moreover, OsCOM1 was loaded normally onto meiotic chromosomes in Osrec8, zep1 and Osmer3 mutants, but could not be properly loaded in Osam1, pair2 and OsSPO11-1(RNAi) plants.
  • The over expression of OsTOP6A1 in transgenic Arabidopsis plants driven by cauliflower mosaic virus-35S promoter resulted in pleiotropic effects on plant growth and development.
  • OsTOP6A1 was predominantly expressed in prepollinated flowers.
  • Although AtSPO11-1, the homolog of OsTOP6A1 in Arabidopsis, has been implicated in meiotic recombination; the present study demonstrates possible additional role of OsTOP6A1 and provides an effective tool for engineering crop plants for tolerance to different environmental stresses.
  • Constitutive expression of a meiotic recombination protein gene homolog, OsTOP6A1, from rice confers abiotic stress tolerance in transgenic Arabidopsis plants.
  • Thus, OsSPO11-1 is essential for both homologous chromosomes pairing and crossover formation during meiosis in rice.
