Nucleotide 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 کاملGeneration 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 کاملthe stady and analysis of rice agroclimatology in lenjan
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولGenotyping common SNP and a microsatellite sequence closely linked to waxy gene in rice by DNA based markers
The potential of different DNA based molecular markers was examined for the detection of single nucleotide polymorphism (SNP) in the waxy gene and a microsatellite (SSR) sequence closely linked to it in a collection of rice varieties. DNA was extracted from leaf samples of 68 different rice cultivars by the CTAB method and specific primers were designed for the amplification of waxy gene and SS...
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 ...
