Guard cells: a dynamic signaling model.
نویسندگان
چکیده
The year 2003 has provided a continuing accretion of knowledge concerning the diverse ways in which guard cells sense and respond to abscisic acid. A deeper understanding of the biochemical mechanisms governing the response of guard cells to blue light has been gained, and new insights have been garnered regarding roles of the extracellular matrix in stomatal regulation.

Systems dynamic modeling of the stomatal guard cell predicts emergent behaviors in transport, signaling, and volume control.
The dynamics of stomatal movements and their consequences for photosynthesis and transpirational water loss have long been incorporated into mathematical models, but none have been developed from the bottom up that are widely applicable in predicting stomatal behavior at a cellular level. We previously established a systems dynamic model incorporating explicitly the wealth of biophysical and ki...
متن کاملEditorial: Signal Transduction in Stomatal Guard Cells
During adaptation of plants to water stress/drought, the tiny pores on the leaf surface, called “stomata,” play a very important role. Stomatal movements can modulate the entry/exit of not only CO2/water (Lawson and Blatt, 2014) but also microbial pathogens (Agurla et al., 2014; Arnaud and Hwang, 2015). The stomatal opening/closure is brought out by changes in the turgor of guard cells. The abi...
متن کاملIntegrating cell biology, image analysis, and computational mechanical modeling to analyze the contributions of cellulose and xyloglucan to stomatal function.
Cell walls are likely to be essential determinants of the amazing strength and flexibility of the guard cells that surround each stomatal pore in plants, but surprisingly little is known about cell wall composition, organization, and dynamics in guard cells. Recent analyses of cell wall organization and stomatal function in the guard cells of Arabidopsis thaliana mutants with defects in cellulo...
متن کاملThe Membrane Transport System of the Guard Cell and Its Integration for Stomatal Dynamics.
Stomatal guard cells are widely recognized as the premier plant cell model for membrane transport, signaling, and homeostasis. This recognition is rooted in half a century of research into ion transport across the plasma and vacuolar membranes of guard cells that drive stomatal movements and the signaling mechanisms that regulate them. Stomatal guard cells surround pores in the epidermis of pla...
