Controlling gene expression in transgenics.

abstract：:Stomata are microscopic structures in the epidermis of the aerial parts of flowering plants formed by two specialized guard cells flanking a central pore. The role of stomata is to optimize gas exchange (the uptake of carbon dioxide and the loss of water vapor) to suit the prevailing environmental conditions. To do th...
