A new transporter gene that regulates plant transpiration

When plants feel stress from a lack of water, they close their epidermal pores, or stomata, to prevent water loss via transpiration. Each stoma is flanked by a pair of guard cells, which change shape to close or open stomata through the exchange of various biological materials. Guard cells therefore play an important role in water evaporation by responding to environmental conditions and stress. However, the mechanisms that control the opening and closing of stomata are not fully understood.
