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.

New insight on how an enzyme ensures the correct growth of pollen tubes in flowering plants has been published today in the open-access journal eLife. The study reveals an unexpected role of ...

a signal is sent to block the growth of the pollen tube, preventing fertilisation. But many pollen grains can land on a stigma and germinate. So, how do plants ensure that each ovule is only ...

Pollen tube growth is one of the fastest examples of cellular growth in all of the plant world, says Mark Westgate, an emeritus professor of agronomy at Iowa State University. “It grows up to one ...

The reason is that the pollen tube in these plants grows incorrectly, which keeps fertilisation from taking place. Pollen tube growth is mainly controlled by two genes that could be useful in crop ...

The two OsRALF peptides are essential for pollen tube germination and elongation, a vital step in the fertilization of rice crops BUSAN, South Korea, Aug. 11, 2023 /PRNewswire/ -- Double ...
