High K+ supply avoids Na+ toxicity and improves photosynthesis by allowing favorable K+:Na+ ratios through the inhibition of Na+ uptake and transport to the shoots of Jatropha curcas plants.
The higher K+ affinity and selectivity compared with Na+ in all organs associated with higher xylem flux and transport to shoots are essential for maintaining adequate K+ : Na+ ratios at the whole-plant level, which allow J. curcas to sustain high rates of photosynthesis and growth even under toxic NaCl levels.
Partial oxidative protection by enzymatic and non-enzymatic components in cashew leaves under high salinity
The work evaluated the role of enzymatic and non-enzymatic antioxidants in cashew (Anacardium occidentale) leaves under 0, 50, 100, 150 and 200 mM NaCl. Salt stress increased protein oxidation and
Antioxidative enzymatic protection in leaves of two contrasting cowpea cultivars under salinity
The aim of this work was to investigate the role of the antioxidant enzymes in salt tolerance comparing the salt-sensitive (Pérola) and a salt-tolerant (Pitiúba) cultivar of cowpea [Vigna unguiculata
Involvement of cation channels and NH4+-sensitive K+ transporters in Na+ uptake by cowpea roots under salinity
The results evidenced that low-affinity Na+ uptake by cowpea roots depends on Ca2-sensitive and Ca2+-insensitive pathways and to a lesser extent NH4+-sensitive K+ transporters.
Salt stress differentially regulates mobilization of carbon and nitrogen reserves during seedling establishment of Pityrocarpa moniliformis.
An integrated analysis of seedling growth, water status, ion accumulation, reserve mobilization, metabolite partitioning, and hydrolyse activity during seedling establishment of the native Caatinga species Piptadenia moniliformis found that starch content increased in the roots of P. monilominis seedlings under 100 mM NaCl, probably in response to the toxic effects of Na+ .
Differences in Cowpea Root Growth Triggered by Salinity and Dehydration are Associated with Oxidative Modulation Involving Types I and III Peroxidases and Apoplastic Ascorbate
The aim of this work was to investigate the balance between the activities of ascorbate peroxidase (APX) and phenol peroxidases (POD) and cowpea root growth in response to dehydration and salt
Changes in physiological indicators associated with salt tolerance in two contrasting cashew rootstocks
The NaCl treatments induced a significant drop in transpiration as a consequence of an increased stomatal resistance in both genotypes, and the tolerant CCP 09 genotype showed better growth performance after two weeks under a large range of NaCl salinity.
