Transient Receptor Potential Canonical (TRPC) channels are implicated in modulating neurite outgrowth. The expression pattern of TRPCs changes significantly during brain development, suggesting that fine-tuning TRPC expression may be important for orchestrating neuritogenesis. To study how alterations in the TRPC expression pattern affect neurite outgrowth,(More)
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)
Circulating hormones stimulate the phospholipase Cβ (PLC)/Ca(2+) influx pathway to regulate numerous cell functions, including vascular tone. It was proposed previously that Ca(2+)-independent phospholipase A(2) (iPLA(2))-dependent store-operated Ca(2+) influx channels mediate hormone-induced contractions in isolated arteries, because bromoenol lactone(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)
This paper considers the segregation of a granular mixture in a rotating drum. Extending a recent kinematic model for grain transport on sandpile surfaces to the case of rotating drums, an analysis is presented for radial segregation in the rolling regime, where a thin layer is avalanching down while the rest of the material follows rigid body rotation. We(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)
Hemicelluloses are the earth's second most abundant structural polymers, found in lignocellulosic biomass. Efficient enzymatic depolymerization of xylans by cleaving their β-(1 → 4)-glycosidic bonds to produce soluble sugars is instrumental to the cost-effective production of liquid biofuels. Here we show that the multi-scale two-phase process of enzymatic(More)
