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 ...

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 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 ...

Flowering plants naturally know when they need to spare or perish their cells. In a new study, an international group of plant biologists has examined the ovules of plant cells by live-imaging to ...

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 ...

Structure of a flower, consisting of a pistil (female part) in the center and stamen (male part) on each side. The pistil has ovules containing egg cells, and the stamen consists of pollen containing ...
