ID 15841
Name UDT1 (GENE SYMBOL)
Synonyms (2)
GRAMENE GENEGR:0080007
Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
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.
