Gene Details:

• MSU gene ID: LOC_Os03g44760
• RAPdb gene ID: Os03g0650400
• Gene Symbol: OsAM1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In contrast, in pair2, Osmer3 and zep1 mutants, OsAM1 could be loaded normally, suggesting that OsAM1 plays a fundamental role in building the proper chromosome structure at the beginning of meiosis.
• In the OsAM1 mutant, pollen mother cells are arrested at leptotene, showing that OsAM1 is required for the leptotene-zygotene transition.
• Finally, we found that the centromeric localization of OsSGO1 depends on OsAM1, not other meiotic proteins such as OsREC8, PAIR2, OsMER3, or ZEP1.
• Very faint OsREC8 foci persisted in the OsAM1 mutant, indicating that OsAM1 is not required for the initial meiotic recruitment of OsREC8.
• In the absence of OsAM1, many other critical meiotic components, including PAIR2, ZEP1 and OsMER3, could not be correctly installed onto chromosomes.
