“…There was reduction of banana yield up to 80 % in affected areas [12,14]. All six DNA components of BBTV-K were amplified using specific primers and as expected all amplicons were approximately 1.0-1.1 kb in size through PCR.…”

“…The crop suffers from many diseases caused by fungus, bacteria as well as viruses. Of the different viral diseases, Banana bunchy top disease caused by BBTV is widely present across the banana growing regions of the world except Latin America [14]. BBTV consists of 18-20 nm diameter icosahedral particles and a multicomponent genome consisting of at least six circular single stranded DNA components encoding for six major proteins [23].…”

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.

“…The history of the spread of the disease has been reasonably well documented perhaps because the symptoms are obvious (Dale, 1987). The disease was subsequently recorded in Formosa (Taiwan) in 1900, Egypt in 1901 and Ceylon (Sri Lanka) in 1913 (Dale, 1987). The disease also arrived in Australia in 1913 in a shipment of infected suckers (banana cuttings) from Fiji.…”

Banana bunchy top virus (BBTV) DNA component 1 from isolates from 10 different countries was cloned and sequenced and the sequences were aligned and compared. This analysis indicated two groups: the South Pacific group (isolates from Australia, Burundi, Egypt, Fiji, India, Tonga and Western Samoa) and the Asian group (isolates from the Philippines, Taiwan and Vietnam). The mean sequence difference within each group was 1.9 to 3.0 % and between isolates from the two groups was approximately 10 %, but some parts of the sequences differed more than others. However, the protein encoded by the major open reading frame, which is probably a replicase, differed by approximately 5 %. The region from the beginning of the stem-loop sequence to the potential TATA box was identical in all isolates except for a two nucleotide change in the Western Samoan isolate and a single change in that of the NSW isolate. These results, together with other evidence, suggest that BBTV has spread to bananas after the initial movement of bananas from the Asian Pacific regions to Africa and the Americas.

“…1). BBTV is widely distributed in banana growing countries in the Asia, Pacific region (Australia, China, Guam, India, Pakistan, Sri Lanka, Hawaii, Indonesia, Japan, the Philippines, Taiwan, Tonga, Samoa and Vietnam) and in a few countries in Africa (Egypt, Gabon, Angola and Burundi) [2,16,50,89,99]. There are many other banana growing regions, South and Central America, the Caribbean, Papua New Guinea, Thailand and in many countries in African and Asia, where BBTV has not been confirmed [43,89].…”

“…It emerged as a serious threat to banana cultivation in many countries, including Fiji in 1927, Egypt and India in 1953, the Philippines and Taiwan in 1961, Tonga and Samoa in 1967, China in 1979, Pakistan and Hawaii in 1989 [2,16]. In Australia, the banana industry in south-east Queensland and northern New Wales was virtually destroyed by the bunchy top disease in 1920 [16]. In India, the disease was introduced from Sri Lanka during 1940 through southern India and now it has spread all over the banana growing region.…”
