A protein regulates photosynthesis

Tokyo, July 31 (reporter LAN Jianzhong) photosynthesis of green plants is the most basic material and energy metabolism in the biological world It uses sunlight to convert carbon dioxide and water into carbohydrates and release oxygen Is this process controllable? Japanese researchers have found that a protein can regulate photosynthesis of plants, and strengthening its function may promote photosynthesis and increase crop yield There are tiny pores on the surface of plant leaves Carbon dioxide required for photosynthesis enters the plant through the pores, and the oxygen produced is discharged into the atmosphere through the pores In a new issue of the online edition of nature communication, Kyushu University's research team led by Professor kaefanghou reported that they found a Arabidopsis mutant with different stomatal opening and closing Through research, they found that a protein called "palrol1" contained in the stomata was related to stomatal opening and closing Using a microscope, the team found that the "patrol 1" protein can transport a protein called "aha1" according to the surrounding environment When the "aha1" protein is transported to the surface of the stomata, the stomata will open, but when it is recycled to the interior of the stomata, the stomata will close After the team planted Arabidopsis with high protein content of "patrol 1", it was found that under the environment suitable for photosynthesis, the stomata of this kind of Arabidopsis can rapidly open a large area, so it is easier to absorb carbon dioxide and make the growth of Arabidopsis more rapid The team said the discovery of the "patrol 1" protein, which is similar to the protein that controls the efficiency of nerve conduction in animals, also helps to compare the evolution of plants and animals.
