Screening of Solanaceous Plants for Resistance and Tolerance to Widespread Begomoviruses in Burkina Faso
Alassane OUATTARA, Kouka Hamidou SOGOBA, Cyrille ZOMBRE, Sonia BAYILI, Kadidia KOÏTA
Solanaceous fruits are economically important and contribute to food security worldwide. Despite this importance, solanaceous crops are confronted with constraints, including begomoviruses. In Burkina Faso, the pepper yellow vein Mali virus (PepYVMLV) and the tomato leaf curl Mali virus (ToLCMLV) have been reported to be the most widespread be(...)

Role of Medicinal Herbs in Sustaining Begomovirus Populations in Burkina Faso: Therapeutic Implications and Ecological Insights
Alassane OUATTARA, Koutoua SEKA, Aboubié Elisabeth ZONGO, Sougrenoma Alice KORBEOGO, Dadjata KERE, Ya Sadia Rabiatou OUATTARA, Kadidia KOÏTA, Oumar TRAORE
Medicinal herbs occupy an important place in the treatment of diseases in Burkina Faso. However, they live near crops which are strongly impacted by diseases with typical symptoms of begomovirus infection. These medicinal herbs may host these viruses, highlighting the need for further study. The purpose of this study was to inventory the medic(...)

Impact of the Seasons on the Evolution of Tomato-infecting Geminivirus and Identification of Plant Reservoirs Harboring Geminivirus in Burkina Faso
Alassane Ouattara, Masséni Yasmine Ouologueme, Bawomon Fidèle Neya, Kouka Hamidou Sogoba, Elise Sanon
Geminiviruses are known as responsible for huge damage to vegetable crops in many tropical, subtropical, and temperate regions. In Burkina Faso, tomato was reported as the most infected vegetable crop with the involvement of several geminivirus species despite its socioeconomic importance. This suggests and underlines the pressing need for add(...)

A new monopartite begomovirus infecting Melochia tomentosa in Burkina Faso
Alassane Ouattara, Dadjata Kéré, Murielle Hoareau, Kadidia Koïta, Pierre Lefeuvre, Jean‑Michel Lett
This is the first description of the complete genome sequence of a newly characterized monopartite begomovirus isolated from an asymptomatic uncultivated plant, Melochia tomentosa, collected in Burkina Faso. The sequence was obtained through rolling-circle amplification, cloning, and Sanger sequencing. The provisional species name “Begomovirus(...)

Les cercosporioses sont les maladies foliaires de l’arachide entraînant le plus de pertes de récolte au Burkina Faso. Pour une production durable de l’arachide, des méthodes de gestion écologique de ces maladies sont nécessaires afin de limiter l'utilisation des fongicides de synthèse. Ainsi, l’objectif de cette étude est d’évaluer l’effet de(...)
