Stomata and transpiration of droopy potatoes.
A diploid potato (Solanum tuberosum) mutant called droopy wilts easily. Excised leaves of the mutant lost weight, and hence water, more rapidly and had many more open stomata than leaves of a normal sibling. Further, the stomata of abnormal plants remained open in wilted leaves. When the stomata of the abnormal mutant were closed by a chemical spray, its excised leaves lost water no more rapidl...
متن کاملFluorometric Measurement of Individual Stomata Activity and Transpiration via a “Brush-on”, Water-Responsive Polymer
Much of atmospheric water originates from transpiration, the process by which plants release H2O from pores, known as stomata, that simultaneously intake CO2 for photosynthesis. Controlling stomatal aperture can regulate the extent of water transport in response to dynamic environmental factors including osmotic stress, temperature, light, and wind. While larger leaf regions are often examined,...
متن کاملEffect of Chemical Control of Stomata on Transpiration of Intact Plants.
In the preceding communication' it was shown that phenylmercuric acetate sprayed upon detached leaves brings about closure of the stomata and thereby diminishes the diffusion of water from the leaves and of CO2 into the leaves. In 9 out of 11 experiments, induced closure of stomata reduced transpiration relatively more than CO2 assimilation as predicted from diffusion theory. This work led to e...
متن کاملDo Really Close Stomata by Soil Drying ABA Produced in the Roots and Transported in Transpiration Stream?
Stomatal aperture responses of Commelina communis L. between well watered plants and water stressed plants were investigated. To see the very rapid response to water stress, the plants were directly rooted out from the soil and exposed to the air immediately. Stomata, rooted out from the soil, were totally closed within 10 minutes without any detention time while the stomata of the plants in th...
متن کاملLewis Thomas and droopy rabbit ears
Tissue injury can occur when the immune system gets over-activated. The first clues to the cause of this immunemediated damage came in the early 1950s from studies of rheumatic fever—a complication of Streptococcal infections that results in tissue destruction in the heart, skin, and joints. Heart lesions typical of rheumatic fever could be induced in experimental animals injected with bacteria...
