Proline Accumulation in Water-stressed Barley Leaves in Relation to Translocation and the Nitrogen Budget.
Mobilization of N from leaves of barley (Hordeum vulgare L.) during water stress, and the role of proline as a mobilized species, were examined in plants at the three-leaf stage. The plants responded to water stress by withdrawing about 25% of the total reduced N from the leaf blades via phloem translocation. Most of this N loss was during the first 2 days while translocation of (14)C-photosynt...
متن کاملContribution of Arginine to Proline Accumulation in Water-stressed Barley Leaves.
Barley (Hordeum vulgare cv Prior) leaves converted l-U-(14)C-arginine to labeled proline. Accumulation of radioactivity in proline was greater in wilted leaves, but only after 9 hours of incubation. As the increase in free proline was detectable after only 3 to 6 hours, it is likely that the observed stimulation of proline labeling represents a result rather than a cause of proline accumulation...
متن کاملProline Oxidase and Water Stress-induced Proline Accumulation in Spinach Leaves.
Spinach (Spinacia oleracea L.) leaf discs accumulated free proline when exposed to polyethylene glycol solutions of water potential less than -10 bars. At -20 bars, the accumulation was 11 micromoles per gram original fresh weight in a 24-hour period.When the leaf organelles were separated on a sucrose gradient, a proline oxidase was detected in the mitochondrial fraction. Isolated mitochondria...
متن کاملBacteroid proline catabolism affects N(2) fixation rate of drought-stressed soybeans.
In prior work, we observed that soybean (Glycine max L. cv Merr.) seeds inoculated with a mutant Bradyrhizobium japonicum strain unable to catabolize Pro (Pro dehydrogenase(-) [ProDH(-)]) resulted in plants that, when forced to depend on N(2) fixation as the sole source of nitrogen and subjected to mild drought stress, suffered twice as large a loss in seed yield as did plants inoculated with t...
متن کاملEffects of Salinity and Laser Radiation on Proline Accumulation in Seeds of Spring Wheat
Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...
