Potato virus M (PVM) is one of the most prevalent viruses infecting potatoes worldwide, showing a wide range of diversity in their populations; however, the diversity and genome information of PVM occurring in India is hardly known. The present study serologically detected the PVM in 22.8% of leaf samples collected from the potato fields, generated...

Temple tree (Plumeria rubra f. acutifolia), an important fragrant-flower tree extensively used in the urban landscaping is known to be infected with a tobamovirus, frangipani mosaic virus (FrMV). In this study, we describe another tobamovirus, Plumeria mosaic virus (PluMV) infecting temple tree in India. PluMV was isolated from an old temple tree c...

Watermelon bud necrosis virus (WBNV) and Groundnut bud necrosis virus (GBNV) are two closely related tospovirus species infecting several crops in India. In the present study, specific diagnostic assays for these two most predominant tospoviruses were developed by comparing host reactions and genome sequence information. Bioassay was developed by s...

Symptoms of little leaf, leaf chlorosis and leaf malformations with mosaic mottling symptoms were observed in two brinjal varieties (Pusa Shyamla and Pusa Purple Cluster) in fields of IARI, New Delhi, India during 2014–2015. Electron microscopy, PCR and sequence analysis first time provided evidence of association of Candidatus Phytoplasma trifolii...

Nature is an attractive source of new therapeutic candidate compounds as a tremendous chemical diversity is found in millions of species of plants, animals, marine organisms, and microorganisms as potential medicinal agents. This chapter of research is an effort to highlight the phytochemical/chemical constituents of an ancient medicinal plant G. g...

Cancer is the second leading cause of death worldwide. Although great advancements have been made in the treatment and control of cancer progression, significant deficiencies and room for improvement remain. A number of undesired side effects such as vomiting, hair loss, immunosupression, free radical formation etc. occur during chemotherapy. Free...

Potato (Solonum tuberosum L.) is an important food crop grown throughout the world. The crop is affected with many plant viruses. Potato virus Y (PVY) and Potato virus X (PVX) are two major viruses that infect potato in single and mixed ways causing considerable yield losses. Unavailability of resistant genes and the tetraploid nature of the crop m...

Characterization of Potato virus M from India based on coat protein gene sequence Akshay Katiyar, Alok Kumar and Bikash Mandal* Advanced Centre for Plant Virology, Division of Plant Pathology, Indian Agricultural Research Institute, New Delhi-110012, India *Corresponding author: leafcurl@rediffmail.com Potato virus M (PVM), a single stranded RNA...

Differential diagnostic assays based on single and duplex RT-PCR for Watermelon bud necrosis virus (WBNV) and Groundnut bud necrosis virus (WBNV) were developed. The sequence differences in the Gn/Gc region of M RNA and nucleocapsid protein (NP) gene of S RNA segment of the two viruses were utilized to design specific primers and RT-PCR was optimiz...
