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 ...

a) Growth of pollen tube towards the ovule. Sperm cells exist at the tip of the tube. Pollen tube contents (PTC) are the liquid part of the pollen tube, shown in yellow. b) Upon pollination to the ...

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have ...
