Assessing the effects of Lecanicillium lecanii in the biological control of early and late leaf spot of peanut in vitro (Burkina Faso, West Africa)
Tounwendsida Abel NANA1, Adama ZONGO, Bawomon Fidèle NEYA, Philippe SANKARA
Early and late leaf spots caused by Cercospora arachidicola and Phaeoisariopsis personata respectively, are the most widespread peanut fungal diseases in West Africa. These diseases lead to notable crop losses in the rural area. In the recent decades, chemical fungicides are used to fight against crop losses, but these chemical substances caus(...)

Synergy between an emerging monopartite begomovirus and a DNA-B component
Alassane Ouattara, Fidèle Tiendrébéogo, Nathalie Becker, Cica Urbino, Gaël Thébaud, Murielle Hoareau, Agathe Allibert, Frédéric Chiroleu, Marie‑Stéphanie Vernerey, Edgar Valentin Traoré, Nicolas Barro, Oumar Traoré, Pierre Lefeuvre, Jean‑Michel Lett
In recent decades, a legion of monopartite begomoviruses transmitted by the whitefly Bemisia tabaci has emerged as serious threats to vegetable crops in Africa. Recent studies in Burkina Faso (West Africa) reported the predominance of pepper yellow vein Mali virus (PepYVMLV) and its frequent association with a previously unknown DNA-B componen(...)

Distribution , diversity and identification of hot spot of Fusarium spp . associated with onion ( Allium cepa L .) in Burkina Faso
SOGOBA Kouka Hamidou, KOÏTA Kadidia, OUATTARA Alassane, NANA Tounwendsida Abel, SOURA Banemane Hervé, CAMPA Claudine
In Burkina Faso, onion (Allium cepa L.) crops are increasingly confronted with numerous biotic threats and diseases caused by fungi are among the main factors constraining onion production. Observation of various Fusarium- like symptoms including seedling melt and basal rot, on onion, suggests the involvement of several species and underlines(...)

Diversity , distribution and prevalence of vegetable-infecting geminiviruses in Burkina Faso
Ouattara A, Tiendrébéogo F, Lefeuvre P, Hoareau M, Claverie S, Allibert A, Chiroleu F, Traoré E V, Barro N, Traoré O, Lett J-M
In West and Central Africa, as in many regions of the world, vegetables are severely affected by geminivirus diseases. In Burkina Faso, observation of various virus-like symptoms, especially on tomato, suggests the involvement of several geminiviruses and underlines the pressing need for additional information on their diversity, distribution,(...)

Exploring the diversity of Poaceae- infecting mastreviruses on Reunion Island using a viral metagenomics- based approach
Sohini claverie, Alassane ouattara, Murielle Hoareau, Denis filloux, Arvind Varsani, philippe Roumagnac, Darren P. Martin, Jean-Michel Lett, pierre Lefeuvre
Mostly found in Africa and its surrounding islands, African streak viruses (AfSV) represent the largest group of known mastreviruses. Of the thirteen AfSV species that are known to infect either cultivated or wild Poaceae plant species, six have been identified on Reunion Island. To better characterize AfSV diversity on this island, we underto(...)

First report of Pepper yellow vein Mali virus associated with pepper yellow vein disease in Cote d’Ivoire
K. Séka, A. Ouattara, K.P. Assiri, K.D. Kra, M. Hoareau, P. Lefeuvre, H. Atta Diallo, J.M. Lett
In Mali and Burkina Faso, pepper yellow vein disease (PYVD) is associated with the Africa monopartite begomovirus Pepper yellow vein Mali virus (PepYVMLV). In January 2012 and August 2013, severe yellowing, leaf curling and deformation symptoms, resembling those of PYVD were observed on pepper (Capsicum spp.) across Côte d'Ivoire. Twenty leaf(...)

New strains of chickpea chlorotic dwarf virus discovered on diseased papaya and tomato plants in Burkina Faso
Alassane Ouattara, Fidèle Tiendrébéogo, Pierre Lefeuvre, Murielle Hoareau, Sohini Claverie, Edgar Valentin Traoré, Nicolas Barro, Oumar Traoré, Arvind Varsani, Jean-Michel Lett
This is the first description of full genome sequences of chickpea chlorotic dwarf virus (CpCDV; genus Mastrevirus; family Geminiviridae) identified in papaya and tomato plants sampled in Burkina Faso. The CpCDV full genome sequences from papaya and tomato share the highest pairwise sequence identity (84% and 93.5%) with Sudanese isolates of t(...)

First reports of Cotton leaf curl Gezira virus and Okra yellow crinkle virus associated with okra leaf curl disease in Cote d'Ivoire.
K. Séka, A. Ouattara, K.P. Assiri, K.D. Kra, M. Hoareau, P. Lefeuvre, H. Atta Diallo, J.M. Lett
Okra leaf curl disease (OLCD) is commonly observed in okra (Abelmoschus esculentus) crops in several African countries. Affected plants are severely stunted with apical leaf curl (upward or downward), distortion and thickening of the veins. In Africa, OLCD is associated with a complex of several strains of two begomovirus species: Cotton leaf(...)

Tomato chlorotic mottle Guyane virus: a novel tomato-infecting bipartite begomovirus from French Guiana
Jean-Michel Lett, Alexandre De Bruyn, Murielle Hoareau, Alassane Ouattara, Sohini Claverie, Anne Dalmon, Damien Laplace, Pierre Lefeuvre, Bruno Hostachy
This is the first description of the complete genome sequence of a new bipartite begomovirus isolated from tomato (Solanum lycopersicum) in French Guiana, for which we propose the tentative name ‘‘tomato chlorotic mottle Guyane virus’’ (ToCMoGFV). DNA-A and -B nucleotide sequences of ToCMoGFV are only distantly related to known New World begom(...)
