Gene Details:

• MSU gene ID: LOC_Os07g43010
• RAPdb gene ID: None
• Gene Symbol: DTM1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Transcripts of UDT1, which functions in tapetum development during early meiosis, were reduced in DTM1 anthers, as were those of PAIR1, which is involved in chromosome pairing and synapsis during meiosis.
• However, expression of MSP1 and MEL1, which function in anther wall specification and germ cell division, respectively, was not altered in the DTM1 mutant.
• Moreover, transcripts of DTM1 were reduced in msp1 mutant anthers, but not in udt1 and pair1 mutants.
• Here we identified a rice gene, DEFECTIVE TAPETUM AND MEIOCYTES 1 (DTM1), which controls the early stages of that development.
• These results, together with their mutant phenotypes, suggest that DTM1 plays important roles in the ER membrane during early tapetum development, functioning after MSP1 and before UDT1, and also in meiocyte development, after MEL1 and before PAIR1.
• The rice gene DEFECTIVE TAPETUM AND MEIOCYTES 1 (DTM1) is required for early tapetum development and meiosis.
• RNA in-situ hybridization analyses showed that DTM1 transcripts were most abundant in tapetal cells at stages 6 and 7, and moderately in the pollen mother cells and meiocytes.
