Soluble sugars make a greater contribution than cell wall components to the variability of freezing tolerance in wheat cultivars.

ABSTRACT: Wheat, the second most produced cereal globally, is primarily cultivated in cooler regions. Unexpected freezing temperatures can severely impact wheat production. Wheat and other temperate plants have a cold acclimation mechanism that enhances freezing tolerance, but reduces growth under low, non-freezing temperatures. During cold acclimation, plants break down storage polysaccharides like starch and fructan to accumulate soluble sugars such as glucose and fructose. These soluble sugars aid freezing tolerance through osmotic adjustments, membrane stabilization, and freezing point depression. However, plant cell walls, composed of insoluble polysaccharides, are the first line of defense against extracellular freezing. We analyzed the contributions of soluble sugars, storage polysaccharides,
