Plants have a secret language that scientists are only now starting to decipher
undefined 28, 2025
Once thought passive, plant cell walls are now recognized as active, dynamic structures that communicate with the cell and environment. Composed of cellulose, pectin, and other polysaccharides, they sense stress, trigger immune responses, and control growth. Pectin’s methylation regulates wall stiffness, shaping cells like interlocking pavement cells via receptors such as FERONIA. Understanding these signals could improve crops, engineer hybrids, and manipulate plant form and resilience.
