A Fragment Substitution in Promoter of MS92/PTC1 Causes Male

发布时间：2021-03-12 15:37

　　Persistent tapetal cell1（PTC1） plays a curial role in pollen development, and is thought to function as a transcriptional activator in rice. However, the molecular mechanism of PTC1 in regulating pollen development and its cis-elements are not well understood. We identified a novel weak male sterility mutant（ms92） which exhibited expanded tapetum and shrink pollen grains. Map-based cloning and allelic analysis suggested that the male sterility of ms92 was caused by a DNA fragment substitution in...
