BACKGROUND Okra (Abelmoschus esculentus; family Malvaceae) is grown in temperate as well as subtropical regions of the world, both for human consumption as a vegetable and for industrial uses. Okra yields are affected by the diseases caused by phyopathogenic viruses. India is the largest producer of okra and in this region a major biotic constraint to(More)
Yellow vein mosaic disease of okra is a whitefly transmitted begomovirus causing heavy economic loss in different parts of India. The okra isolate (OY131) of this virus from a bhendi plant [(Abelmoschus esculentus L.) Moench] showing yellow vein mosaic, vein twisting, reduced leaves, and a bushy appearance in the Palem region, New Delhi, India, was(More)
Yellow vein mosaic disease of okra is major constraint for the production of okra in India. It is caused by whitefly transmitted begomoviruses and results in severe economic losses of the crop. In the present study a new begomovirus (OYBHU isolate) infecting okra showing yellow vein symptoms from Bhubhaneswar, India was characterized. The complete genome(More)
Scalable video coding (SVC) is the ongoing standard as an extension of H.264/AVC to provide stable multimedia services to various service environments and end systems. An exhaustive block motion estimation has been used to determine the best coding mode for each block type in this standard. This achieves a high coding efficiency; however it causes very high(More)
A virus isolate associated with yellow mosaic disease was purified from commercially cultivated jasmine (Jasminum sambac) from Andhra Pradesh, India and it contained flexuous filamentous particles of ~720 × 13 nm. The denatured purified virus had single major polypeptide of molecular weight 32 kDa. Complementary DNA representing 1678 nucleotides (nt) of the(More)
Bacteria were isolated from the midgut of laboratory and field adult flies of Bactrocera zonata (Saunders) (Diptera: Tephritidae), a widely distributed fruit crop pest in India. Nine bacteria were isolated and identified as members of genera Bacillus, Enterobacter, Klebsiella and Stenotrophomonas based on culture-dependent and 16S rRNA gene sequence(More)
A begomovirus isolate (OY136A) collected from okra plants showing upward leaf curling, vein clearing, vein thickening and yellowing symptoms from Bangalore rural district, Karnataka, India was characterized. The sequence comparisons revealed that, this virus isolate share highest nucleotide identity with isolates of Cotton leaf curl Bangalore virus (CLCuBV)(More)
Leaf samples (five) from brinjal/eggplant fields showing upward leaf curling symptoms were collected from Varanasi, Uttar Pradesh state, India. The full length genome of begomovirus and associated betasatellite were amplified by PCR, cloned and sequenced. Sequences of homologous DNA-A and its betasatellite in all samples were the same. The samples failed to(More)
Solitary metastasis of uveal melanoma to bone is extremely rare and usually associated with other organ involvement. We present a rare case of an ocular melanoma patient presenting with solitary metastasis to the clavicle two years after enucleation, without any other organ involvement. In this report, we tried to present our treatment strategy for the(More)
