Biologists find unusual plant gene: abstinence by mutual consent

radicals and also generating a large range of signaling molecules.

Boisson-Derniers discovery demonstrated that peroxisomes play an unexpected key role in the dialogue between the male sperm carrier and the female egg cells. It also implies, the UCSD researchers say, that a diffusible signal generated in the peroxisomes of either the female or male reproductive cells is enough to allow the male-female communication to proceed. This signal coming from the peroxisomes of the male or female is sufficient to set off the eruption of the pollen tube allowing the sperm cells to be released.

The interesting next question is, what is the signal coming from peroxisomes that causes pollen tube bursting" said Schroeder.

Boisson-Dernier added, Why does this signal only cause bursting of the pollen tubes once the pollen tube gets close to the female reproductive cells" These findings actually suggest there may be a second signal or a second key that is needed so the pollen only bursts when male and female are in close vicinity of one another.
