520 |a Polyploidy could increase the interactions of pollen sterility loci and Sb locus interaction cause higher pollen abortion than other loci. Therefore, we focused on the interaction at Sb pollen sterility locus in autotetraploid rice compared to diploid rice hybrid using the near-isogenic lines in the present study. Cytological observations indicated that interaction at Sb locus cause high pollen sterility (69.9%) and abnormal chromosome behavior (37.02%) at Metaphase II in autotetraploid rice hybrid. A total of 139 meiosis-related or meiosis stage-specific genes were detected in the autotetraploid rice hybrid harboring interaction at Sb locus and 27 of these meiosis-related or specific genes displayed significant down-regulation, including four pollen fertility related genes (Rad51, XRI1, PSS1 and MIL1). These results revealed a stronger interaction at Sb pollen sterility locus than other loci, which cause down-regulation of many important meiosis-related genes that were associated with higher pollen sterility in autotetraploid rice hybrids
