Encodes a bHLH transcription factor strongly expressed in the tapetum from late anther stage 5 to early stage 6, and at a lower level in meiocytes. dyt1 mutant exhibits abnormal anther morphology beginning at anther stage 4. DYT1 acts downstream of SPL/NZZ and EMS1/EXS , and regulates the expression of downstream genes like AMS, MS1 and other tapetum preferential genes for pollen development, primarily via TDF1.
