The rice Os03g0752200 was reported as OsSPO11-1 in 2010 [1] by researchers from the China.
Contents
Annotated Information
Gene Symbol
- Os03g0752200 <=>OsSPO11-1
Function
- Spo11 is a homolog of a subunit of archaebacterial topoisomerase, which catalyzes DNA double-strand breaks and initiates homologous chromosome recombination.
- OsSPO11-1 is essential for both homologous chromosomes pairing and crossover formation during meiosis in rice.
Mutation
- The researchers conducted RT-PCR to confirm that the mutant phenotype of the transgenic plants was caused by the defect of OsSPO11-1 gene. Total RNA was extracted from the prepollinated flowers of both wild type and the completely sterile transgenic plants. RT-PCR analysis showed that OsSPO11-1 transcripts in the transgenic plants were downregulated, suggesting that the sterility was caused by the knockdown of OsSPO11-1 gene in these transgenic plants.
