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 ...

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 ...

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 ...

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) ...

Flowers and numerous other land plants rely on animals for fertilization; bees and hummingbirds, even bats and lizards carry pollen from a male to a female plant. In contrast, until recently, it was ...

Recently, Emma Lavaut and her colleagues from Sorbonne University and Universidad Austral de Chile found that a species of red seaweed, Gracilaria gracilis, uses the isopod crustacean Idotea balthica ...

The crucial role of insects in the pollination of flowering plants is well known, but algal fertilization assisted by marine animals was hitherto deemed non-existent. A team has now discovered that ...

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, ...

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 ...
