Pollen Specific Gene Expression during Development and Germination in Tobacco
The pollen grain represents the male part of the sexual reproduction cycle of the higher plant. In itself it combines a transport unit and a producer of sperm cells. Thus the pollen grain or male gametophyte is the effector of the active dispersal of the plant’s genotype. Because of it’s crucial function energetic biochemical, cytological and physiological research has been performed on this highly differentiated haploid organ. Molecular biological processes lying at the basis of pollen development have been studied only in recent years (Giles and Prakash, 1987; Mascarenhas, 1990).
