Explanation
|
This gene plays essentioal role in establishment of homologous chromosome pairing in rice meiosis. During prophase I of the pair1 meiocyte, all the chromosomes become entangled to form a compact sphere adhered to a nucleolus, and homologous pairing failed. Coiled-coil protein. MiMe (Mitosis instead of Meiosis) mutants was generated by editing the OsOSD1 (Os02g37850), PAIR1 (Os03g01590), and OsREC8 (Os05g50410) genes. Q75RY2. AB158462. PO:0020047; microsporocyte ; PO:0000431; megasporocyte.

KC626093-KC626127 (O. sativa and wild rice species, partial cds).
