BARLEY WITH VARIED ACTIVITY OF BRANCHING ENZYME AND STARCH AND STARCH-CONTAINING PRODUCTS WITH INCREASED AMYLOSE CONTENT

摘要

FIELD: agriculture. ^ SUBSTANCE: barley plant including mutation in gene SBE11a, or transgene which codes activity inhibitor of SBE11a, has low level of activity of enzyme SBE11a. Starch produced from grain of such plant may have amylase content of at least 40% (weight/weight). Also, barley of such kind may have lowered levels of activity of SBE11b. Barley grain may have non-rugose phenotype despite damaged amylopectin synthesis path. ^ EFFECT: lower levels of activity of branching enzyme and increased amylase content of starch-containing products. ^ 46 cl, 19 dwg, 7 tbl, 11 ex
