Lolium perenne	expression of FEHs following phytohormone treatments, overview. Expression levels of the enzymes involved in fructan breakdown, are determined following pulse treatments with abscisic acid (ABA), auxin (AUX), ethylene (ET), gibberellic acid (GA), or kinetin (KIN). Lp6-FEH level is increased 48 h following ABA treatment. LpFEH expression levels are increased 48 h following ET treatment, but this increase is significant only for Lp6-FEH. Lp6-FEH expression is increased 24 and 48 h (significant) following AUX and KIN treatment compared to the corresponding controls	up

metabolism	model for fructan and primary carbohydrate metabolism in sink cells of perennial ryegrass, overview	Lolium perenne
physiological function	fructans are polymers of fructose and one of the main constituents of water-soluble carbohydrates in forage grasses and cereal crops of temperate climates. Fructans are involved in cold and drought resistance, regrowth following defoliation and early spring growth, seed filling, they have beneficial effects on human health and are used for industrial processes. Fructan metabolism is under the control of both synthesis by fructosyltransferases (FTs) and breakdown through fructan exohydrolases (FEHs). The accumulation of fructans can be triggered by high sucrose levels and abiotic stress conditions such as drought and cold stress. The activities of enzymes involved in fructan synthesis and breakdown, the expression levels for the corresponding genes and levels for water-soluble carbohydrates are determined following pulse treatments with abscisic acid (ABA), auxin (AUX), ethylene (ET), gibberellic acid (GA), or kinetin (KIN)	Lolium perenne
