Agro-ecological incidence and severity ofPepper veinal mottle virus, genusPotyvirus, family Potyviridae, on cultivated pepper (Capsicum annuumL.) in Nigeria

Incidence and epidemiology ofPepper veinal mottle virus(PVMV), aPotyvirusdisease of pepper

“…Pepper infected by PVMV show varied symptom expressions and disease severity, which may affect the leaves, stem and flowers as well as fruits (Fajinmi et al 1998;Fajinmi 2011). These symptoms include mild mottle, mosaic, vein banding, ring spots, various types of necrosis, leaf discoloration, deformation, blistering and severe stunting of the whole plant (Fajinmi et al 1998;Fajinmi 2006Fajinmi , 2011.…”

“…A survey on the agro-ecological distribution of PVMV, its incidence and severity on cultivated pepper was conducted between 2003 and 2005 in six agro-ecological zones in Nigeria between 2003 and 2005 (Fajinmi 2011). It was reported that the incidences of PVMV diseases were observed to be high in the derived savanna and the humid forest compared with the other agro-ecological zones.…”

Genomic sequencing and analysis of Chilli ringspot virus, a novel potyvirus

“…Potyviruses have a wide host range. Several of them infect chilli peppers and causes significant yield losses [6][7][8]. The recent reports of a new chilli-infecting virus, ChiRSV, in Vietnam [1] and in Hainan, China [3] suggest additional chilliinfecting potyviruses may yet be discovered.…”

Some Selected Serological Diagnostic Techniques in Plant Virology

“…One of such methods is transmission studies, which involves studies on how a virus gets into host plants. Different indicator test plants are mechanically inoculated or graft transmitted with the virus, insect vector transmission of the virus are carried out on series of test plants in specialized insect proof cages so as to provide useful information and further characterizing the virus (Jackie Fajinmi, 2011). Environmental factors may influence the symptom expression of the virus which may serve as a limiting factor but the use of electron microscopy brings further clarification of the virus (Jackie Hughes et al 2004; Fajinmi, 2006;Fajinmi, 2011 In solid phase test, it is an enzymatic reaction, where antibodies are conjugated with a marker enzyme in which the antibody attaches itself with the antigen after recognizing it (Jackie .…”
