First Report of Banana mild mosaic virus Infecting Plantain in Ivory Coast

Abstract

oculated Chenopodium quinoa, C. amaranticolor, Nicotiana benthamiana, N. tabacum (cvs. Havana, Glurk and Turkish), N. glutinosa. Datura stramonium, common bean (cvs. Topcrop and Pinto bean), pumpkin (cv. Small Sugar), pepper (Capsicum annuum, cv. Yolo Wonder) and cucumber (cvs. Emparator and Poinsett 76) plants (results of three independent experiments with six plants per experiment). Symptomless infections were detected in pepper (24 of 30), N. benthamiana (25 of 25), and N. tabacum cv. Turkish (11 of 24) plants by RT-PCR with the pCLV4/pCLVR4 primer pair. To our knowledge, this is the first report of CLVd infecting tomato in Mali. RT-PCR tests of seeds collected from CLVd-infected tomato, pepper, and N. benthamiana plants also detected CLVd (1). Thus, it is possible that CLVd was introduced into Mali in association with seed.

Prevalence of viruses infecting plantain (Musa sp., AAB genome) in the major growing regions in Cote dIvoire

“…In addition, in the 13 regions visited, the viruses identified could infect local cultivars of plantains namely French and False-Horn plantains. Viruses were mentioned on plantains by Kouadio et al (2013) in Cote d"Ivoire, but this study provides some missing information to date on the prevalence of the viruses in the main production areas in relation to cropping systems including plantain. The results showed a predominance of BSOLV and BanMMV in the 13 regions visited and in different cropping systems including plantain.…”

“…The works carried out on the economic impacts of BSV showed that yield losses could reach 70% after a growth cycle on the cultivar Poyo (Cavendish, AAA genome) in the location of Azaguié (Lassoudière, 1979). On plantain (AAB genome), the only study by Kouadio et al (2013) reported for the first time the presence of BanMMV. However, to date no study has been conducted to determine the prevalence and geographical distribution of the three viruses already identified as well as those known worldwide in the production areas on plantains (AAB genome) in the country.…”
