additional information	the transcript levels of the 6&1-FEH in crown tissues slightly increase until snow cover and then decrease under persistent snow cover, while those in leaf tissues appear to be constant. The levels are higher in PI 173438, a snow mold-resistant cultivar. 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	Triticum aestivum	-
additional information	the transcript levels of wfh-sm3 are low in snow mold-resistant cultivars (e.g. PI 173438) that accumulate high levels of fructan. Seasonal changes in the expression of wfh-sm3. Gene wfh-sm3 is correlated with those changes in fructan contents. 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 the gene wfh-sm3, in crown and leaf tissues are suddenly repressed in November and increase under snow cover until early February in crown tissues and until early January in leaf tissues followed by downregulation toward the end of snow cover. The changes in transcript levels of wfh-sm3 only coincide with changes in polysaccharide content in wheat tissues. The transcript levels in crown tissues of cv. PI 173438 are lower in autumn and winter than those in other cultivar	Triticum aestivum	-

General Information

General Information	Comment	Organism
evolution	Wfh-sm3 is an enzyme that is able to hydrolyze almost all components of fructan that has accumulated in hardened wheat tissues	Triticum aestivum
metabolism	regulation of the expression of FEH genes is a crucial factor for overwintering ability of fructan-accumulating cereals andgrasses. 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	Triticum aestivum

physiological function	fructan exohydrolase, FEH, gene plays a key role in fructan metabolism associated with wintering ability, especially for snow mold resistance. Enzyme Wfh-sm3 is able to hydrolyze almost all components of fructan that has accumulated in hardened wheat tissues. The expression of wfh-sm3 may regulate fructan metabolism associated with tolerance for wintering stresses	Triticum aestivum
