rice starch contains only low concentrations of starch bound phosphate monoesters, which limits its usage in various industrial processes. Six stable individual transgenic lines with hyper-phosphorylated starch are produced by the overexpression of the StGWD1 in rice (Oryza sativa japonica cv. Zhonghua 11). The transgenic lines have 9fold and double higher Glc-6-P and Glc-3-P, respectively and increased amylose content. The starch granules display only minor morphological alterations, notably the presence of surface pores and moderately distorted edges and surfaces. The novel starch introduces unique combinations of functionality for rice starch, such as reduced gelatinization temperature, decreased pasting viscosity, increased gel formation capacity and increased gel hardness |
