under osmotic stresses, proline accumulation is an important response of plants to these conditions. proline is a compatible osmolyte which affects many cellular and molecular aspects of plant in both normal and stressful situations. proline is shown to be involved in plant development in normal condition and in conferring resistance to plant under biotic and abiotic stresses. therefore, many s...

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...

abiotic stress such as cold and drought has adverse effects on plants growth and development. abiotic stress resistance is one of the most important goals in plant breeding. this goal can be achieved through transcription factor gene transfer to plants. recent studies show many successes in improving abiotic stress resistance by use of transcription factor gene transfer. the objective of the re...

Salicylic acid (SA) plays many roles in plant physiology. Besides pathogenesis-related resistance, SA is involved in the response to abiotic stress. However, the effects of SA on plant resistance to abiotic stress were found contradictionary, and the actual role of SA in abiotic stress remains unresolved. Generally, deficiency of SA or a very high level of SA increase the plant susceptibility t...

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...

crops growing in salt-affected soils may suffer from physiological drought stress, ion toxicity, and mineral deficiency. a pot study was conducted in 2004-2005 in the aghala area (northern iran) to study the effect of different salinity levels, i.e. ece= 3 (control), 8, 12 and 16 ds m-1 on wheat grain, yield components and leaf ion uptake of four iranian wheat genotypes, i.e. kouhdasht, atrak, ...

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 ...

Throughout plant evolution the circadian clock has expanded into a complex signaling network, coordinating physiological and metabolic processes with environment. Early land plants faced new environmental pressures that required energy-demanding stress responses. Integrating abiotic response system provides control over daily energy expenditure. Here, we describe of in limited, yet compelling, ...

Chickpea (Cicer arietinum L.) is an important food legume crop, particularly for the arid regions including Indian subcontinent. Considering the detrimental effect of drought, temperature and salt stress on crop yield, efforts have been initiated in the direction of developing improved varieties and designing alternate strategies to sustain chickpea production in adverse environmental condition...
