Tomato is sensitive to a number of environmental stresses, especially extreme temperature, drought, salinity and inadequate moisture stresses (Kalloo, 1993). In Bangladesh, lack of irrigation and drought resistant cultivars are the central problems for tomato cultivation. In the dry season with high temperature, flower abortion occurs and fruits drop frequently, which causes very poor yield of ...

Microorganisms could play an important role in adaptation strategies and increase of tolerance to abiotic stresses in agricultural plants. Plant-growth-promoting rhizobacteria (PGPR) mitigate most effectively the impact of abiotic stresses (drought, low temperature, salinity, metal toxicity, and high temperatures) on plants through the production of exopolysaccharates and biofilm formation. PGP...

Upland cotton (Gossypium hirsutum L.), an important source of natural fiber, can tolerate relatively high salinity and drought stresses. In the present study, a plasma membrane Na+/H+ antiporter gene, GhSOS1, was cloned from a salt-tolerant genotype of G. hirsutum, Zhong 9807. The expression level of GhSOS1 in cotton roots was significantly upregulated in the presence of high concentrations of ...

Improved crop varieties are needed to sustain the food supply, to fi ght climate changes, water scarcity, temperature increase and a high variability of rainfalls. Variability of drought and increase in soil salinity have negative effects on plant growth and abiotic stresses seriously threaten sustainable agricultural production. To overcome the infl uence of abiotic stresses, new tolerant plan...

Increasing the grain yield of cereals, which is stable under unfavorable environmental stress, is a major objective to sustain production and feed the growing world population. Recently, we functionally characterized a receptor-like cytoplasmic kinase, named GROWTH UNDER DROUGHT KINASE (GUDK), revealing its role in regulating grain yield under well-watered and drought stress conditions by trans...

Biotic and abiotic stresses, such as fungal infection and drought, cause major yield losses in modern agriculture. Kresoxim-methyl (KM) belongs to the strobilurins, one of the most important classes of agricultural fungicides displaying a direct effect on several plant physiological and developmental processes. However, the impact of KM treatment on salt and drought stress tolerance is unknown....

Salt- and drought-induced alterations in citrulline were assessed in 4 local melon genotypes, 2 sensitive (CU-52, CU-94) and 2 tolerant (CU-196, CU-280), grown in vermiculite in a growth chamber. Salt and drought stresses were started using 30-day-old plants, with 250 mM NaCl and 45 mM PEG (-1.0 MPa) and continued for 12 days. After 12 days under salt and drought conditions, the citrulline cont...

Around 60% of cultivated soils worldwide have plant-growth-limiting problems caused by mineral nutrient deficiencies and toxicities. Therefore, improving the mineral nutritional status of plants under marginal environmental conditions is of great importance for maintenance of crop productivity. In most cases plants growing under marginal environmental conditions (e.g. salinity, low and high tem...

Dehydrins as a group of late embryogenesis abundant II proteins represent important dehydration-inducible proteins whose accumulation is induced by developmental processes (embryo maturation) as well as by several abiotic stress factors (low temperatures, drought, salinity). In the review, an overview of studies aimed at investigation of dehydrin accumulation patterns at transcript and protein ...
