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 ...
متن کاملNucleotide sequence of rice waxy gene.
Rice waxy gene codes for the starch granule-bound starch synthase (EC 2.4.1.11) (1). To characterize its molecular structure, a rice {Oryza sativa subsp. japonica Hengfeng cultivar) genomic library was constructed in XEMBL-3 vector. Two overlapping genomic clones containing waxy gene sequence were screened and identified from this library by using maize waxy gene DNA as probe (kindly provided b...
متن کاملWaxy and non-waxy barley cultivars exhibit differences in the targeting and catalytic activity of GBSS1a
Amylose synthesis is strictly associated with activity of granule-bound starch synthase (GBSS) enzymes. Among several crops there are cultivars containing starch types with either little or no amylose known as near-waxy or waxy. This (near) amylose-free phenotype is associated with a single locus (waxy) which has been mapped to GBSS-type genes in different crops. Most waxy varieties are a resul...

is less indicative of phenotype since iodine binding is reduced in lines with corneous endosperm (Cagampang Visual classification of sorghum [Sorghum bicolor (L.) Moench] and Kirleis, 1985). However, such sorghum starch can grain for the waxy phenotype is subjective and can be confounded be made more amenable to iodine staining by gelatinizaby genetic background, maturity, environment, and expe...
متن کاملPhysicochemical properties and digestibility of hydrothermally treated waxy rice starch.
Waxy rice starch was subjected to annealing (ANN) and heat-moisture treatment (HMT). These starches were also treated by a combination of ANN and HMT. The impact of single and dual modifications (ANN-HMT and HMT-ANN) on the molecular weight (M(w)), crystalline structure, thermal properties, and the digestibility were investigated. The relative crystallinity and short-range order on the granule ...
