Description Rice Undeveloped Tapetum1 (UDT1) is predominantly expressed in the developing panicles, especially abundant in anthers. T-DNA or retrotransposon Tos17 insertions in the Udt1 gene caused male sterility. The anthers phenotype of knockout mutants were normal during the early premeiosis stage, but their tapeta failed to differentiate and became vacuolated during the meiotic stage. Furthermore, meiocytes did not develop to microspores, and middle layer degeneration was inhibited, therefore, the anther locules didn't contain any pollen grains. UDT is localized in the nucleus, and its sequence homology with other basic helix-loop-helix proteins suggests that UDT1 is a bHLH transcription factor.
