Review: Guard cell metabolism and stomatal function (Annu. Rev. Plant Biol.)

Stomatal conductance, g_s, is one of the most important and highly regulated plant processes. Lawson and Matthews review how guard cell metabolism, stomatal anatomy and patterning, and signals from the mesophyll affect g_s which in turn affects plant productivity and water use efficiency. This is an excellent review in its breadth; it covers all processes that control stomatal conductance, from hydraulic capacity and supply, the contribution of subsidiary cells in monocot stomata, starch and sucrose metabolism, ion transport, and coordination between mesophyll and guard cells. One to put on your teaching list! (Summary by Mary Williams @PlantTeaching) Annu. Rev. Plant Biol. 10.1146/annurev-arplant-050718-100251
