Male Sterility

  • P. M. Priyadarshan


Flowers are organized into four concentric whorls of organs, namely, sepals, petals, stamens and carpels. Stamens are the sporophytic organ system with male sporogenous (diploid) cells which undergo meiosis and produce haploid male spores or microspores or pollen grains. Stamen consists of anther and the filament, and the filament is a vascular tissue that supplies water and nutrients to the anther. The production of pollen grains involves an array of extraordinary events that are independent of a conventional meristem, with a transition from sporophytic to gametophytic generation. In addition, production of coenocytic tissues (the tapetum and the microsporocyte mass) is part of pollen development. Subsequently, pollen grains that are self-contained units for genome dispersal are made.
