WebHá 2 dias · It has been known for some time that the gene STOMAGEN (short for “stomata generator”) is crucial for the development of stomata. Previously, researchers have reduced the number of stomata by disabling or “knocking out” the STOMAGEN gene in rice. This leads to an ~80% reduction in the number of stomata. “The literature was able to ... WebThe opening of stomata with increasing temperature was apparently independent of the stomatal response regulated by atmospheric humidity. At high plant water stress, the stomatal response was reversed, i.e., the stomata closed when temperature was gradually increased. This stomatal closure was also independent of the closure regulated by ... WebAlthough evaporation of water through open stomata is a major route of water loss in plants, the stomata must open to allow for the entry of CO 2 used in photosynthesis. In addition, O 2 produced in photosynthesis exits through open stomata. Consequently, a balance must be maintained between the transport of CO 2 and O 2 and the loss of water. houzeo realty
