![]() ![]() We observed a previously unreported mode of polysaccharide and cell wall structural dynamics triggered by water shortage. We investigate the drought response of leaf‐succulent Aloe (Asphodelaceae) species using a combination of histological microscopy, quantification of water content, and comprehensive microarray polymer profiling. However, the role of the cell wall and its polysaccharide composition in relation to drought resistance of succulent plants are unknown. Cell wall polysaccharides are important components of water storage in hydrenchyma cells. Succulent plants have the capacity to tolerate periodically dry environments, due to their ability to retain water in a specialized tissue, termed hydrenchyma. ![]() Plants have evolved a multitude of adaptations to survive extreme conditions.
