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...
متن کاملCircadian redox signaling in plant immunity and abiotic stress.
SIGNIFICANCE Plant crops are critically important to provide quality food and bio-energy to sustain a growing human population. Circadian clocks have been shown to deliver an adaptive advantage to plants, vastly increasing biomass production by efficient anticipation to the solar cycle. Plant stress, on the other hand, whether biotic or abiotic, prevents crops from reaching maximum productivity...
متن کاملPolyamine metabolism and signaling in plant abiotic stress protection
Polyamines (PAs) are small polycationic compounds present in all living organisms. Compelling evidences indicate a role for PAs in plant protection against stress. During the recent years, genetic, molecular and ‘omic’ approaches have been undertaken to unravel the role of PAs in stress signaling. Overall, results point to intricate relationships between PAs, stress hormone pathways and ROS sig...
متن کاملPlant Abiotic Stress: ‘Omics’ Approach
Volume 1 • Issue 3 • 1000e108 J Plant Biochem Physiol ISSN: 2329-9029 JPBP, an open access journal Abiotic stress is the major threat towards the living world more precisely the plant kingdom whose development and productivity is negatively hampered. It is considered as the major cause behind plant damage and reduced crop yield [1]. Plants have developed several biochemical, physiological and m...
متن کاملMolecular 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...
