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 ...

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 ...

Pollen tube guidance towards the ovule is an important step for fertilization in flowering plants. In order for this to happen, a pollen tube attractant peptide LURE guides the pollen tube precisely ...

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 ...

In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...

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 ...

You might think flowers don’t have much choice about who they mate with, given they are rooted to the ground and can’t move. But when scientists from Nagoya, Japan used powerful microscopes to study ...
