Chilling stress in plants ppt
WebA stress response is initiated when plants recognize stress at the cellular level. Stress recognition activates signal transduction pathways that transmit information within the individual cell and throughout the plant. Changes in gene expression may modify growth and development and even influence reproductive capabilities. 11 WebApr 1, 2024 · Cold stress damages cell membranes in plants by altering membrane fluidity ( Fig. 3 ), low water potential, lipid composition, reduced ATP supply, accumulation of toxic compounds, imbalanced ion supply, and solute leakage ( Theocharis et al., 2012 ).
