Improved Cassava Starch by Antisense Inhibition of Granule-bound Starch Synthase I
Molecular Breeding, 2005Cassava is a poor man's crop which is mainly grown as a subsistence crop in many developing countries. Its commercial use was first as animal feed (also known as tapioca), but has shifted since the late sixties to a source of native starch. The availability of native starches, which on the one hand do not require substantial chemical derivatisation and

Effects of Homoeologous Wheat Starch Synthase IIa Genes on Starch Properties
Journal of Agricultural and Food Chemistry, 2012Near-isogenic lines (NILs) of the eight haplotypes of starch synthase IIa (SSIIa) were used to analyze the effects of SSIIa gene dosage on branch chain length, gelatinization, pasting, retrogradation, and enzymatic hydrolysis of starches. Compared to wild-type, the amylopectin of lines missing one or more active SSIIa enzymes had increases in the ...

Natural variation in rice starch synthase IIa affects enzyme and starch properties
Functional Plant Biology, 2004The natural variation in starch synthase IIa (SSIIa) of rice (Oryza sativa L.) was characterised using near-isogenic lines (NILs). SSIIa is a candidate for the alk gene regulating the alkali disintegration of rice grains, since both genes are genetically mapped at the same position on chromosome 6 and related to starch properties.

Functional Plant Biology, 2005
The starch synthase IIa (SSIIa) gene of rice (Oryza sativa L.) has been shown to be the alk gene that controls alkali disintegration of rice grains, although the effects of naturally occurring alk mutant alleles on enzyme function have yet to be determined.

An HPLC method for the assay of starch synthase
Phytochemistry, 1999Abstract A method is presented for the assay of starch synthase activity in plant extracts which does not require the use of radioactive substrates. The method is based on the quantification by HPLC of phosphorylated nucleosides generated in the reaction mixture during incorporation of ADP glucose (ADPGlc) into polymeric glucan. Estimation of starch

Granule‐bound starch synthase I
European Journal of Biochemistry, 2002Starch defines a semicrystalline polymer made of two different polysaccharide fractions. The A‐ and B‐type crystalline lattices define the distinct structures reported in cereal and tuber starches, respectively. Amylopectin, the major fraction of starch, is thought to be chiefly responsible for this semicrystalline organization while amylose is ...
