Most plants allow fungal microorganisms to enter their root cells and provide them with carbohydrates in exchange for a better supply of nutrients and water. Only leguminous plants like peas, beans, ...

Everyone's heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and ...

Flowering plants go through a complicated double-fertilization process that involves a lot of sperm. But until today, researchers hadn’t fully understood the genetic mechanism behind plant sperm ...

In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...

Rapid alkalinization factors (RALFs) are required for pollen tube germination and elongation, an essential process in plant fertilization. But their role in monocot plants remains unexplored.

(A) Pollen grains generated from the stamen pollinate at the tip of the pistil. Pollen tubes grow inside the pistil towards the ovule located in the placenta. (B) The pollen tubes are guided to the ...

Irvine, Calif., April 18, 2005 -- Rare plant species are six times more likely than abundant species to be lost due to nitrogen fertilization of soil, UC Irvine biologist Katharine Suding and ...
