A research team has found some clues to how plants survive in colder regions.
Plants need light to grow, but too much light can induce damage to the photosynthetic complex known as photosystem II. It is known that plants adapted to growing under full sun repair this light-induced damage more. But this repair activity slows down in colder temperatures. An Osaka Metropolitan University-led international research team has now found some clues to how plants survive in colder regions. using ecotypes from around the world.
"What we found in this experiment is that plants acclimated in cold temperatures increase their rate of photoinhibition repair in the cold, and the acclimation capacity is higher in the ecotypes from colder regions," explained Professor Oguchi."But during the warmer seasons, as suggested by the control group, the plants do not increase the rate as the cost of such repair capacity is high.

New research suggests dry air combined with warmer temperatures may prompt bigger than expected changes in how water moves through plants. The adjustment may allow plants to survive with less water ...
