“…Such endogenous pararetroviruses (EPRVs) form a distinct class of retroelements and have been found in a variety of crop and ornamental plants. For example, banana contains, and taro and yucca most likely contain, integrated badnavirus sequences (Clover et al 2003; Yang et al 2003; Geering et al 2005 a , b ; Gambley et al 2008) as well as freely replicating, transmissible, badnaviruses. Eudicots such as Citrus , Theobroma , Ribes and Rubus contain badnaviruses, but it is not known whether they contain integrated badnavirus sequences.…”

“…Badnaviruses are pararetroviruses that infect many economically and culturally important temperate and tropical crops, including sugarcane, banana, citrus, taro, sweet potato, cacao, yam, pineapple, and dracaena, and can infect angiosperms and gymnosperms (1,5,9,11,19,22,32,33,37,41). Badnaviruses are members of the family Caulimoviridae and have bacilliform-shaped virions approximately 30 nm in width and 60 to 900 nm in length that encapsidate a reverse transcribing, circular, noncovalently closed double-stranded (ds)DNA genome of approximately 7 to 9 kbp (4).…”

Sether, D. M., Melzer, M. J., Borth, W. B., and Hu, J. S. 2012. Pineapple bacilliform CO virtis: Diversity, detection, distribution, and transtnission Plant Dis. 96:1798-1804. Members of the genus Badnavirus (family Caulimovirdae) have been identified in dicots and monocots worldwide. The genome of a pineapple badnavirus, designated Pineapple bacilliform CO v;r¡K-HII (PBCOV-HIl), and nine genomic variants (A through H) were isolated and sequenced from pineapple. Ananas comosus, in Hawaii. The 7,451-nucleotide genome of PBCOV-HIl possesses three open reading frames (ORFs) encoding putative proteins of 20 (ORFl), 15 (0RF2), and 211 (ORF3) kDa. 0RF3 encodes a polyprotcin that includes a putative movement protein and viral aspartyl proteinase, reverse transcriptase, and RNase H regions. Three distinct groups of putative endogenous pineapple pararetroviral sequences and Metaviridae-like retrotransposons encoding long terminal repeat, rcverse-transcriptasc, RNasc H, and integrase regions were also identified from the pineapple genome. Detection assays were developed to distinguish PBCOV-HIl and genomic variants, putative endogenous pararetrovirus sequences, and Ananas Metaviridae sequences also identified in pineapple.

Pineapple [Ananas comosus (L.) Merril], cultivated in Benin for it economical importance is affected by Pineapple mealybug wilt, a viral disease. The objectives of this study were to evaluate the determining factors of its prevalence and farmers knowledge on the disease. To achieve these, a total number of 180 farmers, distributed in five communes of southern Benin have been interviewed in 2014 and 2015. In order to identify factors that influence the disease distribution, generalized linear models with the binomial and multinomial distribution family were used to explain the effect of the variables (field and plant levels) and disease severity, respectively. Only factors 'commune' 'and' year ' had a significant effect on the incidence European Scientific Journal November 2016 edition vol.12, No.33 ISSN: 1857 -7881 (Print) e -ISSN 1857 351 at field level (69% in 2014 and 78% in 2015) while three predictors (township, year and variety) explained the severity of the disease and the interaction year -township was significant. Farmers perceive the disease and attribute five causes responsible for its expression. They use height methods to manage the disease. These findings constitute a qualitative as well as quantitative information to build on in designing methods of controlling the disease in order to boost the productivity of pineapple in Benin.Keywords: Distribution, farmers' perception, wilt, pineapple, Benin, cultivé au Bénin pour son importance économique, est essentiellement confronté au virus communément appelé la maladie du wilt. L'évaluation des facteurs influençant sa prévalence et les connaissances des producteurs relatives à la manifestation de la maladie est la préoccupation majeure qui justifie la présente étude. A cet effet, cinq communes ont été prospectées au sud-Bénin au cours des années 2014 et 2015 où 180 producteurs ont été enquêtés. En vue de l'identification des facteurs qui influencent sa distribution, des modèles linéaires généralisés avec la distribution de la famille binomiale et multinomiale ont été utilisés expliquant respectivement les variables incidence (niveaux champ et plant) et sévérité de la maladie. Seuls les facteurs 'commune' et 'année' ont eu un effet significatif sur l'incidence des champs (69% en 2014 et 78% en 2015) tandis que trois prédicteurs (commune, année et variété) ont pu expliquer la sévérité de la maladie et l'interaction année-commune s'est révélée significative. Les producteurs identifient bien la maladie et évoquent cinq causes responsables de sa manifestation. Ils utilisent huit méthodes pour la gestion de cette maladie. Ces informations constituent donc une base capitalisable aussi bien quantitative que qualitative dans l'élaboration des mesures de gestion pouvant être initiées contre la maladie du wilt afin d'améliorer la production de l'ananas au Bénin.
