Banana bract mosaic virus (BBrMV), a member of the genus Potyvirus, family Potyviridae, is the causal agent of the bract mosaic disease (BBrMD) that causes serious yield losses in banana and plantain in India and the Philippines. In this study, global genetic diversity and molecular evolution of BBrMV based on the capsid protein (CP) gene were investigated. Multiple alignments of CP gene of 49 BBrMV isolates showed nucleotide (nt) and amino acid (aa) identity of 79-100 and 80-100 %, respectively. Read More

The banana is one of the world's most important livelihood crops. Banana plants are principally infected by four virus species, (genus ), (genus ), (genus ) and (genus ). The objective of this study is to understand the codon usage pattern and phylogeny of coat protein gene in different banana bract mosaic virus (BBrMV) isolates. Read More

Sugarcane streak mosaic virus (SCSMV), a member of the family Potyviridae, is an important viral pathogen affecting sugarcane production in India. The variability in the nucleotide (nt) and amino acid (aa) sequences of helper component proteinase (HC-Pro) of SCSMV isolates from India was investigated and compared with those of previously published virus isolates from different Asian countries. Comparison of all of the sequenced virus isolates revealed a high level of diversity in the HC-Pro gene (72-97% nt sequence identity; 83-99% aa sequence identity), and the Indian isolates were found to be the most divergent (up to 12% variation at the amino acid level).

The complete genome of banana bract mosaic virus (BBrMV), a Potyvirus belonging to the family Potyviridae causing chlorotic streak disease of cardamom () in India was determined for the first time from a naturally infected cardamom var. Njallani Green Gold through reverse transcription PCR using nine sets of primers designed to different overlapping regions of the genome. The complete genome has 9708 nucleotides excluding poly (A) tail and has the genome organization similar to that of BBrMV isolates infecting banana and flowering ginger (). Read More
