Sequence Diversity of the Nucleoprotein Gene of Peanut bud necrosis virus Isolates from South India

Abstract

Peanut bud necrosis virus (PBNV), genus Tospovirus (family Bunyaviridae), is an important virus infecting peanut and other crops in South India. PBNV isolates naturally infecting groundnut, brinjal, tomato, black gram, field bean, cowpea, cotton, jute, taro and Calotropis plants were collected from different regions of South India and characterized. Infection was confirmed by direct antigen‐coating enzyme‐linked immunosorbent assay (DAC‐ELISA) using PBNV‐specific antiserum. The coat protein gene was further amplified using PBNV coat protein‐specific primers. The amplicon (830 bp) was cloned and sequenced; sequence analysis revealed that the N gene shared 93–100% and 95–100% sequence identity with PBNV at the nucleotide and amino acid levels, respectively.

A Review on Viruses Infecting Taro (Colocasia esculenta (L.) Schott)

“…Taro viruses, which could lead to diseases, damage the crop yield and sometimes lead to plant death [17]. Multiple viruses have been found to infect taro, including the four main viruses; Dasheen mosaic virus (DsMV) , Taro bacilliform virus (TaBV) , Colocasia bobone disease virus (CBDV) , and Taro vein chlorosis virus (TaVCV) [5,6,8,9,17,18,19,20,21,22,23,24,25,26] that this review will centre on. This review will also mention a relatively new virus Taro bacilliform CH virus (TaBCHV) [17,19,27].…”
