Quantitative trait loci affecting amylose, amylopectin and starch
... maize endosperm [21, 25]. Starch is separable into several components, all of them glucose polymers: amylose (AM) an essentially linear unit, amylopectin (AP) a branched molecule of very high molecular mass (5·106) and phytoglycogen a highly branched and soluble polymer. The AM:AP ratio is rather co ...
