Diagnosis of banana bunchy top virus in Red banana
Banana Bunchy Top Disease (BBTD) caused by the Banana Bunchy Top Virus (BBTV), is the most serious virus disease of banana and plantain worldwide. Detection of the BBTV infection in the planting material could help in the effective management of the disease in banana. A polymerase chain reaction (PCR) assay was used to detect the of banana bunchy top virus at early stages of infection in banana...
متن کاملReassortment and concerted evolution in banana bunchy top virus genomes.
The nanovirus Banana bunchy top virus (BBTV) has six standard components in its genome and occasionally contains components encoding additional Rep (replication initiation protein) genes. Phylogenetic network analysis of coding sequences of DNA 1 and 3 confirmed the two major groups of BBTV, a Pacific and an Asian group, but show evidence of web-like phylogenies for some genes. Phylogenetic ana...
متن کاملUnusual events involved in Banana bunchy top virus strain evolution.
Banana bunchy top virus (BBTV) can be transmitted by aphids and consists of at least six integral components (DNA-R, -U3, -S, -M, -C, and -N). Several additional replication-competent components (additional Reps) are associated with some BBTV isolates. A collected BBTV strain (TW3) that causes mild symptoms was selected to study the processes in BBTV evolution. Southern blot hybridization, poly...
متن کاملIN VITRO MICROPROPAGATION OF BANANA (Musa spp.)
The present study was conducted at the Biotechnology Laboratory, Biotechnology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during the period from September 2004 to June 2005 to investigate the effect of different concentrations of BAP and NAA on virus free plant regeneration, shoot multiplication and different concentrations of IBA and IAA on in vitro root formation of ...
متن کاملEvidence for two groups of banana bunchy top virus isolates.
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 differe...
