Parthenium hysterophorus is a plant that tolerates drought and salinity to an extremely high degree. Higher expression of stress-responsive proteome contributes for greater defence against abiotic stresses. Thus, P. hysterophorus could be a rich source of genes that encode stress-imparting mechanisms and systems. The present study utilizes comparative physiological and proteomic approaches for ...

Climate-change-driven stresses such as extreme temperatures, water deficit, and ion imbalance are projected to exacerbate and jeopardize global food security. Under field conditions, these stresses usually occur simultaneously and cause damages that exceed single stresses. Here, we investigated the transcriptional patterns and morpho-physiological acclimations of Brachypodium dystachion to sing...

germination stage is an important stage of plant growth stage that often is affected by environmental stress including water and salinity stresses including drought and salinity. in order to study germination characteristics of scrophularia striatain water and salinity stress conditions at different temperatures an experiment was conducted. temperatures regimes included 5, 10, 15, 20, 25, 30 an...

present study was conducted to investigate the effects of different osmotic potentials (0.0 mpa, -0.4 mpa, -0.8 mpa and -1.2mpa) induced by nacl and polyethylene glycol-6000(peg) as salinity and drought stress respectively on germination and early growth of two inbred lines of maize (mo17 and b73). the objective was to compare the germination ability between tow maize inbred lines in salt and d...

Plant hormones play an important role in plant response to abiotic stresses, by both stimulation of defence pathways and regulation of plant growth and development. The key hormone in the response to stresses associated with dehydration is abscisic acid (ABA). Its levels were followed during the response to salinity or drought in two species differing in their stress tolerance – radish and toba...

Suboptimal growth conditions, such as low rhizosphere temperature, high salinity, and low pH can negatively affect the rhizobia-legume symbioses, resulting in poor nodulation and lower amounts of nitrogen fixed. Early stages of the Bradyrhizobium japonicum-soybean [Glycine max (L.) Merr.] symbiosis, such as excretion of genistein (the plant-to-bacteria signal) and infection initiation can be in...

Reactive oxygen species play a key role in the response of plants to abiotic stress conditions. Their level is controlled in Arabidopsis thaliana by a large network of genes that includes the H(2)O(2)-scavenging enzymes cytosolic ascorbate peroxidase (APX) 1 and 2. Although the function of APX1 has been established under different growth conditions, genetic evidence for APX2 function, as well a...

This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in Persian gulf and Oman sea ecology research center. In this experiment, larvae were fed on 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments with 3 repetitions including a c...
