DNA Markers Detecting Non-glutinous Rice in Glutinous Rice Processed Food

Functional Properties of Glutinous Rice Flour by Dry-Heat Treatment

Glutinous rice flour (GRF) and glutinous rice starch (GRS) were modified by dry-heat treatment and their rheological, thermal properties and freeze-thaw stability were evaluated. Compared with the native GRF and GRS, the water-holding ability of modified GRF and GRS were enhanced. Both the onset and peak temperatures of the modified samples increased while the endothermic enthalpy change decrea...

Molecular evidence on the origin and evolution of glutinous rice.

Glutinous rice is a major type of cultivated rice with long-standing cultural importance in Asia. A mutation in an intron 1 splice donor site of the Waxy gene is responsible for the change in endosperm starch leading to the glutinous phenotype. Here we examine an allele genealogy of the Waxy locus to trace the evolutionary and geographical origins of this phenotype. On the basis of 105 glutinou...

Glycemic effects of rice and glutinous rice on treated-type II diabetic subjects.

Generation of new glutinous rice by CRISPR/Cas9-targeted mutagenesis of the Waxy gene in elite rice varieties.

In rice, amylose content (AC) is controlled by a single dominant Waxy gene. We used Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated 9 (Cas9) to introduce a loss-of-function mutation into the Waxy gene in two widely cultivated elite japonica varieties. Our results show that mutations in the Waxy gene reduce AC and convert the rice into glutinous ones without ...

Gastroprotective Effects of Glutinous Rice Extract against Ethanol-, Indomethacin-, and Stress-induced Ulcers in Rats

This study was designed to evaluate the efficacy of an orally administered aqueous extract of glutinous rice (GRE) to protect against acute gastric mucosal lesions induced by ethanol, indomethacin, and water immersion restraint stress in rats and to characterize the active substances responsible for the protection. GRE was shown to dose-dependently prevent the gastric lesions induced by the abo...
