Under natural conditions pollen vectors act stochastically, and the order in which pollen arrives can influence seed paternity. In a number of wind-pollinated taxa, however, fertilization does not ...

This is a preview. Log in through your library . Abstract The modular morphology of plants has important consequences for reproductive strategies. Ovules are packaged in discrete structures (flowers) ...

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 ...

Peking University, May 6, 2025: The research team led by Qu Lijia and Zhong Sheng from the School of Life Sciences and the Peking-Tsinghua Center for Life Sciences has discovered a conserved "two-step ...

Pollination in plants is the transfer of pollen from the anther (male part of the flower) to the stigma (female part). Following pollination, fertilization must then occur through the union of male ...

I discussed some basics of plant pollination and fertilization last week in this column. This week, let's look at some of the problems and anomalies of these processes. Every summer, questions about ...

During summer and fall, we all enjoy a plethora of fruits from our home gardens and from the local farmers market. Each fruit starts with a flower. Then four separate events will take place in ...

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, ...

Another summer of above-normal summer temperatures in much of the country may be taking its toll on your vegetable gardens. Temperature extremes can interfere with flowering and fruit set, resulting ...

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 ...
