Banana bunchy top virus (BBTV; family Nanoviridae, genus Babuvirus) is a multi-component single-stranded DNA virus, which infects banana plants in many regions of the world, often resulting in large-scale crop losses. We analyzed 171 banana leaf samples from fourteen countries and recovered, cloned, and sequenced 855 complete BBTV components including ninety-four full genomes. Importantly, full genomes were determined from eight countries, where previously no full genomes were available (Samoa, Burundi, Republic of Congo, Democratic Republic of Congo, Egypt, Indonesia, the Philippines, and the USA [HI]). Accounting for recombination and genome component reassortment, we examined the geographic structuring of global BBTV populations to reveal that BBTV likely originated in Southeast Asia, that the current global hotspots of BBTV diversity are Southeast Asia/Far East and India, and that BBTV populations circulating elsewhere in the world have all potentially originated from infrequent introductions. Most importantly, we find that rather than the current global BBTV distribution being due to increases in human-mediated movements of bananas over the past few decades, it is more consistent with a pattern of infrequent introductions of the virus to different parts of the world over the past 1,000 years.

“…Based on phylogenetic analysis of DNA-R, Karan et al [26] divided BBTV isolates into two groups such as a PIO group and South-East Asian (SEA) group. BBTV isolates from India were found to be belonging to the PIO group [6,37,41]. Similarly, Amin et al [3] characterized the Pakistan (Sindh) isolate of BBTV by analyzing of sequences of DNA components and indicated that BBTV present in Pakistan belongs to the PIO group.…”

Bunchy top disease of banana caused by Banana bunchy top virus (BBTV, genus Babuvirus family Nanoviridae) is one of the most important constraints in production of banana in the different parts of the world. Six genomic DNA components of BBTV isolate from Kandy, Sri Lanka (BBTV-K) were amplified by polymerase chain reaction (PCR) with specific primers using total DNA extracted from banana tissues showing typical symptoms of bunchy top disease. The amplicons were of expected size of 1.0-1.1 kb, which were cloned and sequenced. Analysis of sequence data revealed the presence of six DNA components; DNA-R, DNA-U3, DNA-S, DNA-N, DNA-M and DNA-C for Sri Lanka isolate. Comparisons of sequence data of DNA components followed by the phylogenetic analysis, grouped Sri Lanka-(Kandy) isolate in the Pacific Indian Oceans (PIO) group. Sri Lanka-(Kandy) isolate of BBTV is classified a new member of PIO group based on analysis of six components of the virus.

“…Vishnoi et al (2009) reported that BBTD incidence occurred between 20-30% between 2006 to 2007 in India northern zones of Lucknow, Barabanki, Bahraich, Kanpur, and Etawah districts of Uttar Pradesh. Recently, there was a report on the newly isolate BBTV complete genome which was identified in Meghalaya, India and Pacific India Ocean group (Banerjee et al, 2014).…”

Bananas are one among the world's leading food crops after rice, wheat and maize. Banana cultivation is affected by various diseases. Among them, in globally banana bunchy top disease (BBTD) caused by the banana bunchy top virus (BBTV) and Fusarium wilt caused by the Fusarium oxysporum f.sp. cubense are the most serious diseases. BBTV is an isometric virus with a circular single stranded DNA (ssDNA) genome consisting of at least six components, BBTV DNA-1 to 6. The virus is transmitted by the banana aphid (Pentalonia nigronervosa). In this review paper, we are discussing the global status of BBTD, symptom expression in both vegetative and reproductive stage, resistant strategy and recent BBTV resistant banana clones development.
