additional information seasonal changes in mRNA levels of FEH genes (1-FEH, 6-KEH, 6&1-FEH, 6-FEH, Wfh-sm3) in crown and leaf tissues of winter wheat sampled in the field from autumn to spring (2009/2010), overview. Transcript levels of 1-FEH w1 is constant in leaves and changes according to plant growth rate in crown tissues. The transcript levels of 1-FEH w1 both in crown and leaf tissues of the freezing-tolerant cultivars, Valuevskaya and Norstar, are higher than those of cv. PI 173438 Triticum aestivum

General Information

General Information Comment Organism
evolution the enzyme belongs to the glycoside hydrolase family 32, GH32 Triticum aestivum
metabolism regulation of the expression of FEH genes is a crucial factor for overwintering ability of fructan-accumulating cereals and grasses. The coordinated expression of FEH genes in wheat is related to the regulation of water-soluble carbohydrate accumulation from autumn to early winter and fructan consumption under snow cover as well as energy supply. Wheat FEHs also play an important role in the varietal difference in freezing tolerance and snow mold resistance. Cooperative expression of 6-FEH and 1-FEH genes might be related to the seasonal changes and varietal difference in mono- and disaccharide contents Triticum aestivum
physiological function fructan exohydrolase, FEH, gene plays a key role in fructan metabolism associated with wintering ability, especially for snow mold resistance. Gene 1-FEH w1 is thought to code a trimming enzyme Triticum aestivum
