EMERGING DATA ON POLLEN TUBE GROWTH AND FERTILIZATION IN FLOWERING PLANTS, 1990-1995 [Review]

摘要

Since its discovery at the end of the last century, double fertilization remains of central interest in plant reproductive biology research. Although the sequence of events leading to fertilization is well known from cytological studies, the underlying mechanisms remain to be elucidated. This now seems feasible by the diversification and refinement of recently developed technologies presented in this review. The progress made during the last five years in understanding pollen tube guidance, discharge into the embryo sac, and gametic fusion are described. Future directions are also discussed.
