Fructan composition and physiological roles in wheat, tall fescue, and timothy.

摘要

Fructan is the major storage form of water-soluble carbohydrate (WSC) in vegetative tissues of many economically important plants. An understanding of their structures is important for elucidating their metabolic pathways and physiological roles. Discerning the physiological roles of fructan reveals how these compounds fit into the scheme of nature.;Vegetative tillers of wheat (Triticum aestivum L.), tall fescue (Festuca arundinacea Schreb.), and timothy (Phleum pratense L.) were cultured in pots of soil at 21;The response of fructan to drought in levels of tall fescue was studied in 4- to 6-week-old vegetative plants growing at 19
