Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, ...

Sexual reproduction of plants requires pollen to land on the stigma, which then germinates and grows pollen tubes through the style to deliver sperm cells to the ovule. Pollen tubes are the ...

The study of pollen viability and germination relies on a suite of techniques designed to evaluate the functionality of pollen grains before their use in breeding, conservation or ecological studies.

Fertilization in flowering plants relies on the fast-growing pollen tube, a cellular conduit that delivers sperm cells to the ovule. This study sheds light on the vesicle trafficking mechanisms that ...

In flowering plants, successful reproduction hinges on the growth of a specialised cellular extension—the pollen tube—which conveys non‐motile sperm cells from a germinated pollen grain through female ...

New insight on how an enzyme ensures the correct growth of pollen tubes in flowering plants has just been published. New insight on how an enzyme ensures the correct growth of pollen tubes in ...

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.
