This is an important advance in the studies of reproductive biology. However, there is little information on the interaction (the penetration and exchange of substances) between vegetative nucleus (VN) and generative cell (GC) or sperm cells within MGUs. If there exists, what kind of substance Will it be and how will it work, and what physiological function will it have? This is a very important problem which needs to be solved as soon as possible.展开更多
文摘Up to now, male germ units (MGUs)have been found in many angiosperms. This is an important advance in the studies of reproductive biology.

If there exists, what kind of substance Will it be and how will it work, and what physiological function will it have? This is a very important problem which needs to be solved as soon as possible.
