In cold weather, rice pollen suffers in a variety of ways as it struggles to develop
A team of botanists in Japan have overturned decades-old assumptions about how cold stress leads to pollen sterility in rice.

A team of botanists in Japan have overturned decades-old assumptions about how cold stress leads to pollen sterility in rice.
The mysterious and complex patterns on pollen walls may self-organise – and far earlier than expected.
Male flowers of Aconitum protect their pollen by adding alkaloids. Without pollen as a reward, botanists asked how the flower compensated pollinators.
For many people, pollen means nose itching and eyes watering – but it is so much more. It is the reason we have food on our plates, and flowers around us. When pollen forms abnormally or degenerates, it is unable to generate new life through the production of a seed. Many factors can affect pollen development, and this is what my research is about.
The widespread tendency towards declining fruit set from first to last flowers on plants may contribute to temporal variation in allocation optima.
There’s an insufficiency of people to grow the new crops that aren’t being identified because of the dearth of plant taxonomists. Where will it all end..?
Kron et al. use flow cytometry to characterize pollen loads from individual bees, using DNA content as a species marker,
