Plant biologists at ITbM, Nagoya University, have made a key discovery that the contents in pollen tubes alone can increase the size of seeds, without the need for fertilization. This new plant ...

The researchers, who explored why ovules continue to attract pollen tubes after failed double fertilization, have also provided molecular clues for the survival of some plant species after the loss of ...

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 ...

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 ...

ANY biologically aware parent who has started talking about the birds and the bees will have realised halfway through that what they are really discussing is flowers. Bees carry pollen grains from one ...

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 ...

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 ...

Researchers led by Dr. LI Hongju from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences have revealed that the female gamete in flowering plants controls ...
