Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plants control their water consumption via adjustable pores ...

Hydrogen sulphide (H₂S) is an endogenously produced gasotransmitter that has rapidly emerged as an active signalling component of several plant processes, stomatal movement regulation among them. The ...

Detached broad bean (Vicia faba L.) leaflets were water stressed; within 15 minutes, guard-cell abscisic acid (ABA) concentration increased ninefold. This result eliminates the apparent discrepancy ...
