Salinity is one of the most important abiotic stresses that decrease crop production. Transcription factors (TFs) are prominent regulators in plant responses to abiotic stress. In the present study, the expression pattern of four salt-induced genes encoding transcription factors, namely, MYB, RF2, GTF, and ARID was studied in response to salt stress (sodium chloride) and recovery conditions. Th...

Plants growing in their natural habitats are often challenged simultaneously by multiple stress factors, both abiotic and biotic. Research has so far been limited to responses to individual stresses, and understanding of adaptation to combinatorial stress is limited, but indicative of non-additive interactions. Omics data analysis and functional characterization of individual genes has revealed...

Sorghum is an important crop that can absorb and accumulate abundant Si ranging, improving tissue toleranceto the water salt stress reducing sodium absorption. T hus, objective was to verify induction of resistance ingermination seedling growth sorghum seeds during germination due treatment with silicon.Two experiments were carried out two cultivars (EA03 EA955) solution potassium silicatesolut...

salinity and flooding are as two very important factors of soil degradation. they often occur together and cancause severe damage to plants. however, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. a pot study was conducted in 2005-2006 in northern aq qala (northern iran) to studycombine effects of waterlogging and soil salinity at different growth s...

drought, as an abiotic stress inflicts destructive and harmful effects on plants at their different growth stages. plants react differently to drought. among their reactions is the production of such osmolytes as proline and glycine betaine. it seems that, through exogenous application of these materials, plant resistance to drought stress can be increased. therefore, a factorial experiment, ba...

RING finger proteins play an important role in plant adaptation to abiotic stresses. In the present study, a wild tomato (Solanum habrochaites) cold-induced RING-H2 finger gene, ShATL78L, was isolated, which has been identified as an abiotic stress responsive gene in tomato. The results showed that ShATL78L was constitutively expressed in various tissues such as root, leaf, petiole, stem, flowe...

In field conditions, plants are often simultaneously exposed to multiple biotic and abiotic stresses resulting in substantial yield loss. Plants have evolved various physiological and molecular adaptations to protect themselves under stress combinations. Emerging evidences suggest that plant responses to a combination of stresses are unique from individual stress responses. In addition, plants ...

To survive, plants must respond rapidly and effectively to various stress factors, including biotic and abiotic stresses. Salinity stress triggers the increase of cytosolic free Ca2+ concentration ([Ca2+]i) via Ca2+ influx across the plasma membrane, as well as bacterial flg22 and plant endogenous peptide Pep1. However, the interaction between abiotic stress-induced [Ca2+]i increases and biotic...
