A resurrection has started in haploid and double haploid research in the twenty-first century. The haploid and double haploid could be achieved through in vivo and in vitro anther and microspore culture techniques. Fixing the homozygosity is the most striking benefit of androgenesis. Various factors like genotypic dependency, growth condition, developmental stage of the microspore, pre-treatment, culture media, regeneration media, growth hormones, and various chemicals have a direct effect.

Rice anthers from Nipponbare in the flowering stage were collected, proteins extracted and shotgun proteomic analysis conducted. From three biological replications, total 3,198 non-redundant rice anther proteins were identified. There was no bias of physiochemical properties in identified proteins. Proteins showing wide p
Male sterility is an important trait for crop breeding program based on heterosis. Recent advances in molecular researches have led to the identification of genes involved in plant reproductive development and understanding the molecular functions of rice male gametophyte including roles of phytohormones in reproduction process. Here, we review the genes required for key aspects of anther/pollen development and conventional methods for the production of hybrid seeds in rice. Finally, we discuss the molecular approaches for the generation of male-sterile lines through the regulation of phytohormonal biosynthesis in reproductive organs.
