    摘要： The invention provides barley gain comprising a reduced level or activity of starch synthase IIa protein and a starch content of at least 41% (w/w) and methods of producing, identifying and using same. The grain may comprise an amylase content of at least 50%, a β-glucan content of 5-9% (w/w) or greater than 9% (w/w), and/or a fructan content of 3-11% (w/w). The fructan may comprise a degree of polymerization from about 3 to about 12. For example, the plant and grain comprises a sex6-292 allele and/or an amo1 mutation. A food or beverage product, and methods of producing a food or beverage product, comprising obtaining or producing the subject grain and processing the grain to produce the product. Also contemplated are methods of improving one or more indicators of health in a mammal comprising administering a composition comprising the subject barley grain or a product comprising same.

    摘要： The specification provides methods of obtaining a genetically modified plant which has increased production potential compared to a control plant, the method comprising the steps of i) obtaining a plurality of plants at least one of which comprises in its genome a heterologous polynucleotide, ii) identifying from the plurality of plants a plant which has increased production potential relative to the control plant and comprises the heterologous polynucleotide, and iii) selecting the genetically modified plant, wherein the polynucleotide comprises a transcriptional control sequence operably linked to a nucleic acid sequence which encodes an agent that modifies endogenous starch phosphorylation and/or starch degradation in the plant. In some embodiments, the plant has increased endogenous glycosylase or increased digestibility compared to a control plant. In some specific embodiments, the endogenous starch phosphorylation and/or starch degradation is modified by modifying expression or activity of one or more enzymes selected from the group consisting of α-amylase (EC 3.2.1.1), β-amylase (EC 3.2.1.2), glucoamylase (EC 3.2.1.3), starch phosphorylase (EC2.4.1.1), glycosylase (EC 3.1.33), sucrase-isomaltase (EC 3.2.10), amylomaltase (EC 2.4.1.25), maltase (EC 3.2.1.20), isoamylase, and α-glucan, water dikinase (GWD, EC 2.7.9.4).
