The HIC (H-I-C) gene down•regulates the development of these structures in carbon-rich environments.
The HIC (H-I-C) gene down•regulates the development of these structures in carbon-rich environments. Regulation of these structures in response to water potential can be iso•hydric or an•iso•hydric. The Ball-Berry-Leuning model couples carbon assimilation rates to the conductance of these structures, which can be measured with por•o•meters. Export of protons causes cells surrounding these structures to take up potassium ions from subsidiary cells. These structures are inactive during the day in (*) CAM plants. Root-released abscisic acid decreases the turgor of the guard cells surrounding these structures, causing them to close. Through these structures, which are primarily on the leaf underside, water is lost to transpiration and carbon dioxide is taken in. For 10 points, name these pores that control gas exchange through leaf surfaces.
