“…MSV is widely distributed across sub-Saharan Africa as well as on Indian Ocean islands (Thottappilly et al, 1993 ;Peterschmitt et al, 1991). Five MSV clones have been sequenced fully, isolated in Nigeria (Mullineaux et al, 1984 ;Boulton et al, 1991), Kenya (Howell, 1984), South Africa (Lazarowitz, 1987) and La Re!…”

Three maize streak virus (MSV) isolates were derived from an MSV population used to assess the response to infection of maize cultivars. Isolate SP1 was obtained from this population through short acquisition and inoculation periods (1 and 5 min, respectively), using a single Cicadulina mbila vector. Isolate SP2 was derived from SP1 after transmission to a wild perennial host (Coix lacryma-jobi), on which it was maintained for about 4 years without insect transmission. Isolate N2A, the most pathogenic isolate, was obtained from the initial population after serial passages on almost completely resistant inbred maize lines. The complexity of each isolate was analysed by RFLP analysis and sequencing based on 120 SP1 clones, 36 SP2 clones and 40 N2A clones. All three isolates were composed of different but related clones, consistent with a

“…Maize streak has been the most important and widespread virus disease of maize in sub-Saharan Africa and several Indian Ocean Islands for more than 100 years (Fuller, 1901;Lapierre & Signoret, 2004;Storey, 1925;Thottappilly, Bosque-Perez, & Rossel, 1993). The disease continues to cause significant losses and food insecurity across sub-Saharan Africa (Martin & Shepherd, 2009).…”

“…According to Asanzi et al (1994) Maize streak virus has been reported to cause a significant maize disease in Nigeria (Thottappilly et al 1993). The disease epidemic has been reported in Nigeria in 1971, 1973(Fajemisin and Shoyinka 1976Kim et al 1981;Efron et al 1989).…”

Several programmes have been initiated for the development of maize varieties with resistance traits of Maize streak virus (MSV) by International Institute of Tropical Agriculture (IITA), Ibadan, and have been released to farmers and research scientists. Therefore, a survey was conducted in five states in the south west of Nigeria (Oyo, Ogun, Ondo, Ekiti and Osun) during the raining planting season to determine the incidence of MSV disease by visual examination and serodiagnostic screening of symptomatic plants. The determination of infection rate of MSV disease by Cicadulina triangular on maize plant and its distribution from the lowest diseased leaf was also studied. The mean MSV disease incidence observed in these states was 35.95% which confirms the presence of MSV in the south west of Nigeria. Sero-diagnostic screening of virus-induced symptomatic leaf samples indicated that out of the 250 leaves sampled per state, 24.4% tested positive for MSV in Oyo, 25.6% in Ondo, 34% in Ogun, 19.6% in Ekiti and 38.8% in Osun. In two-week-old plants, symptoms developed on the leaves that were emerging at the time of inoculation, while in six-week-old plants, symptoms developed on the leaves directly below the emerging leaves irrespective of the number of C. triangular used. These suggest that the lowermost leaf with symptoms of the disease indicates the growth stage at which a plant was infected. There was a relationship between symptom expression and plant age which could be very effective when carrying out surveys to gather information for epidemiological studies. In addition, the 10 varieties of maize inoculated with MSV through C. triangular transmission showed no significant difference in disease severity over time irrespective of the number of C. triangular used.
