OCCURRENCE OF MULBERRY MOSAIC VIRUS IN EGYPT
Journal Title: International Journal of Microbiology Research - Year 2014, Vol 6, Issue 2
Abstract
Mosaic, yellowing and malformation symptoms were detected on leaves of mulberry plants (Morus spp. L.), grown in the Experimental Farm of Faculty of Agriculture, Ain Shams University, Cairo, Egypt, during the spring of 2012. Viral assay experiment which carried out on sensitive host (Phaseolus vulgaris), resulted in appearance of virus-like symptom. The detected virus was found to have a narrow host range. Electron microscopy studies of ultrathin sections of healthy and infected mulberry leaves revealed that the detected virus affected the plant cell structure of the diseased plants. The viral particles were icosahedral in symmetry and double capsid of 57 nm in diameter and the diameter of the inner core was found to be 42 nm. The isolated mulberry mosaic virus is a tentative member of the Genus Begomovirus in the Family Geminiviridae. Isozyme polymorphism in the healthy and infected plants was studied. Differences were detected in the ideogram of peroxidase, α-esterase and β-esterase isozymes of the infected plants relative to that of the healthy plants. According to the available literature, this may be the first report of mulberry mosaic virus in Egypt.
