Osmotic adjustment by intact isolated chloroplasts in response to osmotic stress and its effect on photosynthesis and chloroplast volume.
Spinach leaf chloroplasts isolated in isotonic media (330 millimolar sorbitol, -1.0 megapascals osmotic potential) had optimum rates of photosynthesis when assayed at -1.0 megapascals. When chloroplasts were isolated in hypertonic media (720 millimolar sorbitol, -2.0 megapascals osmotic potential) the optimum osmotic potential for photosynthesis was shifted to -1.8 megapascals and the chloropla...
متن کاملPhotosynthesis by intact isolated chloroplasts on solid support.
A new approach to measurements of photosynthesis by isolated chloroplasts has been devised. Intact isolated chloroplasts were trapped in the cavities of membrane filters. The thin layers of chloroplasts so obtained were assayed for O(2) evolution and CO(2) assimilation in leaf-chambers. Photosynthetic gas exchange could be demonstrated to take place either in a closed or a flow-through system. ...
متن کاملThe Photosynthesis, Na+/K+ Homeostasis and Osmotic Adjustment of Atriplex canescens in Response to Salinity
Atriplex canescens (fourwing saltbush) is a C4 perennial fodder shrub with excellent resistance to salinity. However, the mechanisms underlying the salt tolerance in A. canescens are poorly understood. In this study, 5-weeks-old A. canescens seedlings were treated with various concentrations of external NaCl (0-400 mM). The results showed that the growth of A. canescens seedlings was significan...
متن کاملMonitoring Response of a Few bZip Transcription Factors in Response to Osmotic Stress in Sunflower
Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...
متن کاملPhotosynthesis by isolated chloroplasts.
Photosynthesis in green plants requires not only photoelectron transport, oxygen evolution, and photophosphorylation, but also the synthetic reactions whereby carbon dioxide is assimilated and reduced to a number of organic compounds via the photosynthetic carbon reduction cycle1 and secondary biosynthetic pathways.2 Complete photosynthesis with isolated chloroplasts has for many years been a g...
