Abscisic acid (ABA) is one of the “classical” plant hormones, ie discovered at least 50 years
ago, that regulates many aspects of plant growth and development. This chapter reviews our …

Two highly specialized cells, the guard cells that surround the stomatal pore, are able to
integrate environmental and endogenous signals in order to control the stomatal aperture …

Melatonin has been detected in plants in 1995; however, the function and signaling pathway
of this putative phytohormone are largely undetermined due to a lack of knowledge about its …

Abscisic acid (ABA) regulates numerous developmental processes and adaptive stress
responses in plants. Many ABA signaling components have been identified, but their …

Stomatal pores are formed by pairs of specialized epidermal guard cells and serve as major
gateways for both CO2 influx into plants from the atmosphere and transpirational water loss …

Plant drought stress response and resistance are complex biological processes that need to
be analyzed at a systems level using genomics and physiological approaches to dissect …

Low temperature, drought, and high salinity are common stress conditions that adversely
affect plant growth and crop production. The cellular and molecular responses of plants to …

Stomatal opening is largely promoted by light-activated plasma membrane-localized proton
ATPases (PM H+-ATPases), while their closure is mainly modulated by abscisic acid (ABA) …

Abscisic acid (ABA) regulates many agronomically important aspects of plant development,
including the synthesis of seed storage proteins and lipids, the promotion of seed …

Plant secondary metabolites are unique sources for pharmaceuticals, food additives, flavors,
and other industrial materials. Accumulation of such metabolites often occurs in plants …
