During a survey conducted in the grapevine orchards of Himachal Pradesh, variety of symptoms ranging from leaf yellowing, vein greening, reduced leaf size, downward rolling/cup shaped leaves to reduced fruit bearing were observed. Symptomatic leaf samples were collected and analyzed by serological (DAS-ELISA) and molecular methods (RT-PCR, PCR) for viruses(More)
Apple is the major commercial horticulture crop in Himachal Pradesh and other hill states of Jammu & Kashmir, Uttarakhand and some parts of Northeastern states of India. In order to gather data on health status and incidence of virus and virus-like pathogens in apple orchards, survey was conducted in the month of June and September, 2010 in Hatkoti, Rohru,(More)
Chrysanthemums worldwide suffer from a high incidence of infection with chrysanthemum virus B (CVB), a member of the genus Carlavirus, family Betaflexiviridae. Three major lineages or strains of this virus have been found in India, but none have been characterized beyond the genetic variation they display in their coat protein genes. Here, we describe the(More)

Since the first attempt at glaucoma surgery in 1830 many surgical procedures have been devised and adopted depending on the understanding of the aetiology and pathogenesis of the disease. Trabeculectomy, the most recent drainage procedure for glaucoma, has become a widely used, effective, and safe method, particularly for chronic simple glaucoma. Up to 4(More)
AIM To evaluate the success rate and complications of pneumatic retinopexy performed at a university hospital and to identify which patients are best suited for pneumatic retinopexy. METHODS This was an interventional case series. Retrospective review of 61 patients who had pneumatic retinopexy performed by two retina surgeons at two University of(More)
A rapid and sensitive two-step RT-PCR protocol for simultaneous detection of major apple viruses, namely Apple mosaic virus (ApMV), Apple stem pitting virus (ASPV), Apple stem grooving virus (ASGV), Apple chlorotic leaf spot virus (ACLSV) and Apple scar skin viroid (ASSVd), was developed. Five specific primer pairs were tested and confirmed for these(More)
Cherry necrotic rusty mottle virus (CNRMV) and Cherry virus A (CVA) are important graft transmitted viruses in the family Betaflexiviridae, infecting cherry. It is believed that CVA causes severe symptoms and disease in combination with other stone fruit viruses in both cherry and non-cherry hosts while CNRMV infected tree show reduced growth, significant(More)
The present study identified natural infection of Apple stem grooving virus in five bamboo species. “Himalayan ‘maggar’ bamboo, widely distributed in the Western Himalayas, is abundantly found in and around the campus of CSIR-IHBT. Some of the plants near the apple germplasm and nursery field at this institute displayed virus-like symptoms such as(More)
Among apple viruses, the present study identified Apple stem grooving virus infection in Bauhinia variegata . CP gene of the isolate clustered with kiwi isolate, however, differing in biological characteristics. Bauhinia variegata, widely distributed in Kangra district (Himachal Pradesh, India), was found to exhibit severe virus-like symptoms, which(More)
Cherry necrotic rusty mottle virus (CNRMV) is a graft transmitted virus, known to infect sweet cherries and some other Prunus species. Recently, this virus has been explored for its natural hosts and has emerged as a significant virus in India, infecting many species of bamboos with a high incidence of 65 %, thereby expanding its host range. A wild rose(More)
