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.

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 ...

(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 ...

Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives ...

Plant domestication is the process of adapting plants to human use by selecting specific traits. The selection process often involves the modification of some components of the plant reproductive ...
