The Role of Microtubules in Stomatal Opening
In contrast to most plant cells, the cortical microtubules of guard cells remain well organized even after microfibril deposition and cellular differentiation is complete. This has led some researchers to speculate that microtubules might play an important role in the regulation of stomatal function. However, recent pharmacological studies concerning the effects of microtubule inhibitors on sto...
متن کاملThe ultraviolet action spectrum for stomatal opening in broad bean.
The ultraviolet action spectrum for stomatal opening was measured using epidermal peels from leaves of broad bean (Vicia faba). The spectrum was calculated from hyperbolic fluence response curves using 11 wavelengths ranging from 275 to 459 nm. The action spectrum exhibits a major peak at approximately 280 nm and a minor peak at approximately 360 nm. The response at 280 nm is about three times ...
متن کاملFLOWERING LOCUS T Regulates Stomatal Opening
Stomatal pores surrounded by a pair of guard cells in the plant epidermis control gas exchange for photosynthesis in response to light, CO(2), and phytohormone abscisic acid. Phototropins (phot1 and phot2) are plant blue-light receptor kinases and mediate stomatal opening via activation of the plasma membrane H(+)-ATPase. However, the signaling mechanism from phototropins to the H(+)-ATPase has...
متن کاملStomatal opening: role of potassium uptake.
Fischer (I ) proposes that his results "strongly suggest that the basic mechanism of stomatal opening, in response to light plus CO2-free air, is stimulation of the uptake of potassium." I believe that his evidence supports the opposite conclusion (2) that "in order to account for stomatal opening, the guard cells would have to absorb 13 times as rapidly as the most rapidly absorbing cells." Fi...
متن کاملRelation between senescence and stomatal opening: Senescence in darkness.
THE SENESCENCE (PROTEOLYSIS AND LOSS OF CHLOROPHYLL) OF ISOLATED LEAVES OF OAT SEEDLINGS IN THE DARK IS INHIBITED OR DELAYED BY COMPOUNDS OF SIX DIFFERENT TYPES: phenazine methosulfate, fusicoccin, alpha,alpha'-dipyridyl, cycloheximide, spermidine, and two cytokinins. In every case but the last, these compounds in optimum concentration caused the stomata to open and remain partly or completely ...
