Discuss various strategies acquired by plants to adapt stress
Answers
Answer:
:Several biotic and abiotic stresses affect plant growth, development and crop productivity. To cope up all these stresses, plant develops certain efficient strategies to avoid or tolerate the stresses which allow them to adapt and defense themselves from stress situations. Such adaptation strategies are at morphological, anatomical, biochemical and molecular levels. Molecular crosstalk, epigenetic memories, reactive oxygen species (ROS) signaling, accumulation of plant hormones such as salicylic acid, ethylene, jasmonic acid and abscisic acid, change in redox status and inorganic ion fluxes, R-gene resistance and systemic acquired resistance (SAR) are some of the modifications/mechanisms adopted by plants to adapt and defense themselves from the environmental stress. The novel “omics” technologies allow the researchers to identify the genetics behind plant stress response and adaptation and provide unbiased data that can be precisely used to investigate the complex interplay between the plants, its metabolism and the stress environment.
