barley (hordeum vulgare l.) is a model plant, as genetic and physiological studies are concerned. abiotic stresses such as drought adversely affect the growth of plants. the objective of this experiment was to identify the responsive genes to osmotic stress, using macroarray (covering 13050 genes). rna was extracted from 5 barley genotypes in stress as well as in normal conditions at 3 times of...

In plants, abiotic stresses induce various physiological changes and growth inhibition that result in adaptive responses to these stresses. However, little is known about how such stresses cause plant growth inhibition. Many genes have been reported to be repressed in plants under abiotic stress conditions. ZPT2 (for petunia [Petunia hybrida] zinc-finger protein 2)-related proteins with two Cys...

Low temperature, drought and salinity are major adverse environmental factors that limit plant productivity. Understanding the mechanisms by which plants perceive and transduce these stress signals to initiate adaptive responses is essential for engineering stress-tolerant crop plants. Molecular and biochemical studies suggest that abiotic stress signaling in plants involves receptor-coupled ph...

Drought negatively impacts plant growth and the productivity of crops around the world. Understanding the molecular mechanisms in the drought response is important for improvement of drought tolerance using molecular techniques. In plants, abscisic acid (ABA) is accumulated under osmotic stress conditions caused by drought, and has a key role in stress responses and tolerance. Comprehensive mol...

Elucidating the key players of molecular mechanism that mediate the complex stress-responses in plants system is an important step to develop improved variety of stress tolerant crops. Understanding the effects of different types of biotic and abiotic stress is a rapidly emerging domain in the area of plant research to develop better, stress tolerant plants. Information about the transcription ...

Drought and other types of abiotic stresses negatively affect plant growth and crop yields. The abscisic acid-, stress-, and ripening-induced (ASR) proteins play important roles in the protection of plants against abiotic stress. However, the regulatory pathway of the gene encoding this protein remains to be elucidated. In this study, the foxtail millet (Setaria italica) ASR gene, SiASR4, was c...

Various abiotic stresses such as drought, high salinity, high temperature, and low temperature negatively impact plant growth and productivity of crops. Plants have adapted to respond to these stresses at the molecular, cellular, physiological, and biochemical level, enabling them to survive. Various adverse environmental stresses induce the expression of a variety of genes in many plant specie...

osmotic stress is one of the major factors that significantly reduce yields in dry areas. plants respond to this abiotic stress at physiological and molecular levels. many genes are induced under stress conditions by transcription factors. dehydration responsive element binding (dreb) protein is a subfamily of ap2/erf transcription factors which control expression of many osmotic stress-inducib...

APETALA2/Ethylene-Responsive Factor (AP2/ERF) gene family is plant specific transcription factor. It plays critical roles in development process, tolerance to biotic and abiotic stresses, and responses to plant hormones. However, limited data are available on the contributions of AP2/ERF gene family in barley (Hordeum vulgare L.). In the present study, 121 HvAP2/ERF genes in barley were identif...
