Plants acclimate to the changing environmental conditions by adjusting their molecular responses at different molecular levels including genome, epigenome, transcriptome, metabolome, and proteome levels to ensure survival. Plants adapt to abiotic stresses by establishing a ‘stress memory’ of previous exposures to mild stresses. Stress memory helps plants to develop tolerance and survive recurring exposures to the stress conditions. This memory establishes a new cellular state that differs from the state of unexposed naïve plants. This...
