Having identified a tomato pollen gene associated with blocking self-pollination in petunias and cross-species fertilization in tomatoes, researchers conclude that tomato plants use similar ...

Researchers found that attractant peptides released by female tissues initiate rapid depolymerization and repolymerization of actin at the leading edge of the pollen tube tip, steering its direction ...

The overall rate of self-fertilization can be viewed as the sum of two distinct processes: 1) self-pollination of all ovules in a flower (whole-flower self-pollination); and 2) self-pollination of ...

In a typical pollination scenario, the spiky, genome-packed pollen from a flower’s male stamen attaches itself to the fuzzy torso of a bee. The bee travels to the next flower in search of more nectar, ...

• Generally, in gymnosperms, pollination and fertilization events are temporally separated and the developmental processes leading the switch from ovule integument into seed coat are still unknown.

Question: My zucchini blossoms and after the blossom falls off there is no vegetable. This happened last year with purchased plants and this year from plants I grew from seed. Do you have any idea ...

Tomato plants use similar biochemical mechanisms to reject pollen from their own flowers as well as pollen from foreign but related plant species, thus guarding against both inbreeding and ...
