Molecular mechanisms in plant abiotic stress response

Molecular Mechanisms in Plant Abiotic Stress Response

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...

Plant Responses to Simultaneous Biotic and Abiotic Stress: Molecular Mechanisms.

Plants are constantly confronted to both abiotic and biotic stresses that seriously reduce their productivity. Plant responses to these stresses are complex and involve numerous physiological, molecular, and cellular adaptations. Recent evidence shows that a combination of abiotic and biotic stress can have a positive effect on plant performance by reducing the susceptibility to biotic stress. ...

Plant Abiotic Stress

Abiotic stress such as cold, drought, salt, and heavy metals largely influences plant development and crop productivity. Abiotic stress has been becoming a major threat to food security due to the constant changes of climate and deterioration of environment caused by human activity. To cope with abiotic stress, plants can initiate a number of molecular, cellular , and physiological changes to r...
