2.4.1.242	evolution	diversification of GBSS genes in plants, overview	723548	
2.4.1.242	evolution	genotyping and phylogenetic analysis, starch phenotyping	736995	
2.4.1.242	malfunction	a null mutation of the Wx gene in each of the three genomes is associated with starch almost entirely consisting of the branched glucan polymer amylopectin (waxy starch), with corresponding changes in functionality	759036	
2.4.1.242	malfunction	Arabidopsis thaliana ptst mutants synthesise amylose-free starch and are phenotypically similar to mutants lacking GBSS. Mutation of the CBM domain of PTST causes GBSS to remain in the plastid stroma	737059	
2.4.1.242	malfunction	loss of GBSS activity results in starch granules containing mostly amylopectin and little or no amylose (phenotype waxy)	705654	
2.4.1.242	malfunction	phenotyping of a GBSSIa or GBSSIb null mutant	736995	
2.4.1.242	malfunction	waxy wheat, which accumulates amylose-free starch, is developed by the elimination of granule-bound starch synthase I (GBSSI),1 which is responsible for amylose synthesis in endosperm tissue. Starch of Wx wheat shows a modified gelatinization curve, with a lower gelatinization onset temperature, higher peak viscosity, and lower setback compared to wild-type wheat	722432	
2.4.1.242	metabolism	relationships among amylose and amylopectin accumulation and enzyme activities related to starch synthesis, involving GBSS, overview	722897	
2.4.1.242	metabolism	the enzyme is involved in the synthesis of amylose	759036	
2.4.1.242	metabolism	tropical tree Cecropia peltata is a rare example of an organism able to make either polymer type, glycogen and starch. Glycogen accumulates to very high levels in specialized myrmecophytic structures (Müllerian bodies), whereas starch accumulates in leaves. Compared with polymers comprising leaf starch, glycogen is more highly branched and has shorter branches, factors that prevent crystallization and explain its solubility	736982
