The mechanism of plant mitosis has also been studied in some detail. The formation and development of the embryo sac in plants have also been studied. Work is now going on in investigating the pattern of formation of the embryo sac of orchids and rice. In order to improve the quality of newly developed rice products a thorough understanding of the structural components of the rice grain is important, because these components in combination determine textural, sensory and nutritional quality. The ontogeny of the aleurone layer.
Emphasis is on the pattern of formation of the aleurone granules in the aleurone cells.
The genes responsible for the formation and control of starch and protein in the rice grain have been studied using the FISH techniques. V. Key words Isolation and identification of plant generative and sperm cells. Plant cell cytoskeletal structures. Cell and tissue culture. Structure of starch, protein bodies and lipid globules in rice grain.
