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 KATANIN ...

Researchers have used a unique microscopic technique to examine the dynamics of pollen tubes in the Arabidopsis plant. They were able to observe the mechanism of one-to-one pollen tube guidance, a ...

Researchers found that attractant peptides released by female tissues initiate rapid depolymerization and repolymerization of actin at the leading edge of the pollen tube tip, steering its direction ...
