Abstract:
Sugarcane is the main cash crop of the Pakistan. Pakistan is the seventh largest Sugarcane
producing country. Major loss of sugarcane yield is due to Sugarcane mosaic virus which
belongs to family potyvirid, largest family of plant viruses containing single stranded
positive sense RNA.Three major proteases are included in the genome of the SCMV i.e.
P1, Hc Pro, N1a, P2-1 helper component. P1 is the major non conservative protein of the
SCMV. Non-conservative nature of the P1 gene of the sugarcane is responsible for
determining host range of the sugarcane. The Identification and cloning of the P1 gene of
the Sugarcane mosaic virus will be helpful for screening of the infected sugarcane cultivars
of the Pakistan.
