Phytic acid (InsP(6)) is considered to be the major source of phosphorus and inositol phosphates in most cereal grains. However, InsP(6) not utilized efficiently by monogastric animals due lack phytase enzyme. Furthermore, its ability chelate mineral cations, phytic an antinutrient that renders these minerals unavailable for absorption. In view facts, reducing content grains a desired goal genetic improvement several crops. present study, we report RNAi-mediated seed-specific silencing...
Rice yield is greatly affected by environmental stresses such as drought and salinity. In response to the challenge of producing rice plants tolerant these stresses, we introduced cDNA encoding transcription factors DREB1A DREB1B under control stress inducible rd29 promoter. Two different indica cultivars were used, BR29, an improved commercially cultivated variety from Bangladesh IR68899B, IRRI bred maintainer line for hybrid rice. Agrobacterium mediated transformation BR29 was done...
One out of three humans suffer from micronutrient deficiencies called “hidden hunger”. Underprivileged people, including preschool children and women, most deficiency diseases other health-related issues. Rice (Oryza sativa), a staple food, is their source nutrients, contributing up to 70% daily calories for more than half the world’s population. Solving hunger” through rice biofortification would be sustainable approach those people who mainly consume have limited access diversified food....
Summary Vitamin‐A deficiency (VAD) is a major malnutrition problem in South Asia, where indica rice the staple food. Indica‐type varieties feed more than 2 billion people. Hence, we introduced combination of transgenes using biolistic system transformation enabling biosynthesis provitamin A endosperm several cultivars adapted to diverse ecosystems different countries. The seed‐specific glutelin promoter (Gt‐1 P) was used drive expression phytoene synthase ( psy ), while lycopene β‐cyclase...
Rice being a staple food, contains little iron in the edible grain. To increase nutrition rice grains, our present study highlights first time development of high grain by exploring endosperm specific overexpression endogenous ferritin gene. The gene has been cloned from and overexpressed under control GlutelinA2 (OsGluA2) promoter. After genetic transformation aromatic indica cultivar, Pusa-sugandhi II, milled seeds resulting T3 transgenics exhibited 7.8-fold overexpression, which...
Summary Rice sheath blight, caused by the necrotrophic fungus R hizoctonia solani , is one of most devastating and intractable diseases rice, leading to a significant reduction in rice productivity worldwide. In this article, order examine blight resistance, we report generation transgenic lines overexpressing oxalate oxidase 4 ( O soxo4 ) gene green tissue‐specific manner which breaks down oxalic acid OA ), pathogenesis factor secreted . Transgenic plants showed higher enzyme activity OxO...
Abstract Background Phytic acid (InsP 6 ) is considered as the major source of phosphorus and inositol phosphates in cereal grains. Reduction phytic level grains desirable view its antinutrient properties to maximize mineral bioavailability minimize load waste management. We report here RNAi mediated seed-specific silencing myo -inositol-3-phosphate synthase ( MIPS gene catalyzing first step biosynthesis rice. Moreover, we also studied possible implications on -inositol related metabolism,...
We report here the overexpression of Rab16A full length gene (promoter + ORF), from salt-tolerant indica rice Pokkali, in salt-susceptible variety Khitish, via particle bombardment. Molecular analysis transgenics revealed stable integration transgene upto T2 generation. High level expression (driven by its own stress-inducible promoter), as well protein, was detectable leaves under simulated salinity stress (250 mM NaCl, 24 h); being higher than wild type (WT) plants. The transcript also...
