Perspective Advancements in Plant Science through Segregating Sorghum Gametophyte Developmental Stages

Sweet sorghum (Sorghum bicolor L. Moench) is an important C4 crop that holds significant promise for sustainable agriculture and bioenergy production. Recent breeding and biotechnology advances on this multipurpose crop were aimed at enhancing the yield, quality, and resilience. Microspores, which can be described as precursors of pollen grains have a pivotal role in plant reproduction for angiosperms. The molecular mechanisms underlying progression of these male gametophytes, from their initiation within the anthers to the formation of mature pollen grains, have functional significance in plant reproduction and evolution. Regulatory pathways in microspore development play an important role for evolutionary adaptation of this potential biofuel crop. This manuscript provides a comprehensive overview on the use of S. bicolor microspores while delving into the developmental pathways influencing their fate per genetic factors.
