An in vitro plant regeneration and genetic transformation protocol was established in jute (Corchorus capsularis L. var JRC321). One-day-old apical, meristematic tissues of germinating seedlings were used as explants. Multiple shoots were regenerated from each explant using Murashige and Skoog basal medium containing 1.78 µM benzylamino purine and 4.92 µM(More)
We report a pH-dependent conformational transition in short, defined homopolymeric deoxyadenosines (dA(15)) from a single helical structure with stacked nucleobases at neutral pH to a double-helical, parallel-stranded duplex held together by AH(+)-H(+)A base pairs at acidic pH. Using native PAGE, 2D NMR, circular dichroism (CD) and fluorescence(More)
Resveratrol (5-[(E)-2-(4-hydroxyphenyl)ethenyl]benzene-1,3-diol), a redox active phytoalexin with a large number of beneficial activities is also known for antibacterial property. However the mechanism of action of resveratrol against bacteria remains unknown. Due to its extensive redox property it was envisaged if reactive oxygen species (ROS) generation(More)
Over-expression of the unedited mitochondrial orfB gene product generates male sterility in fertile indica rice lines in a dose-dependent manner. Cytoplasmic male sterility (CMS) and nuclear-controlled fertility restoration are widespread developmental features in plant reproductive systems. In self-pollinated crop plants, these processes often provide(More)
Genetically engineered rice lines with broad insecticidal properties against major lepidopteran pests were generated using a synthetic, truncated form of vegetative insecticidal protein (Syn vip3BR) from Bacillus thuringiensis. The selectable marker gene and the redundant transgene(s) were eliminated through Cre/ lox mediated recombination and genetic(More)
An in vitro plant generation and genetic transformation protocol was established in sesame (Sesamum indicum L. cv Rama) through biolistic particle gun bombardment. 5-day-old apical, meristematic tissues of in vitro-germinating seedlings were used as explants. 10–15 Multiple shoots were generated from each explant using Murashige and Skoog basal medium(More)
Lathyrus sativus L. (Grass pea) is the source for cheap and nutritious food choice in drought and famine susceptible zones in greater part of North India and Africa. The non-protein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) has been known for decades for its potent neurotoxic effect, causing irreversible neurodegenerative disease(More)
The motor domain of myosin is the core element performing mechanochemical energy transduction. This domain contains the actin and ATP binding sites and the base of the force-transducing lever. Coordinated subdomain movements within the motor are essential in linking the ATPase chemical cycle to translocation along actin filaments. A dynamic subdomain(More)
