Survey of the incidence and distribution of five viruses infecting yams in the major yam producing zones in Benin Eni, A.O.; Hughes, Jacqueline d'Arros; Rey, M.E.C. (2008)Surveys were conducted in 2004 and 2005 to determine the incidence and distribution of viruses infecting yams in fourmajor yam-producing agro-ecological zones in Benin. Yam leaves collected from 69 fields and one experimental screen house were indexed for Cucumber mosaic virus (CMV), Dioscorea mottle virus (DMoV), Yam mild mosaic virus (YMMV), Yam mosaic virus (YMV) and yam-infecting badnaviruses [Dioscorea alata bacilliform virus (DaBV) and Dioscorea sansibarensis bacilliform virus (DsBV)] by ...
Kumar, L.; Waliyar, F.; Kumari, S. (2008)Chickpea (Cicer arietinum L.) is the most important pulse crop and is an important source of dietary protein. It is mainly grown in Indian subcontinent, Ethiopia, Turkey, Mexico, and some regions around the Mediterranean and in the Middle East. Recently the crop is gaining prominence in Canada and Australia. Two types of chickpea are grown commonly, the ‘desi’type in Indian subcontinent and ‘kabuli’ type in West Asia and Mediterranean region, and this type is gaining popularity. Several viruses ...
Detection and identification of begomoviruses from landraces of okra (Abelmoschus esculentus) in Cameroon Leke, W.N.; Ramsell, J.N.; Titanji, V.P.; Legg, J.P.; Brown, J.; Ngeve, J.; Njualem, D.; Fondong, V.N.; Kvarnheden, A. (2006)Virus diseases present major constraints to production of okra (Abelmoschus esculentus) in Cameroon. However, the identity of these viruses had not been determined prior to this study. Detection of begomoviruses in okra using polymerase chain reaction (PCR) has been problematic because of interfering polysaccharides and phenolics. We report the use of FTA® Classic Cards as an effective means of collecting, extracting, storing, and retrieving begomovirus DNA from okra leaf samples. Leaves presenting ...
