Abstract
Carica papaya papaya is a fruit crop that is cultivated mostly in kitchen gardens throughout Nepal Leaf samples of C papaya plants with leaf curling vein darkening vein thickening and a reduction in leaf size were collected from a garden in Darai village Rampur Nepal in 2010 Fulllength clones of a monopartite Begomovirus a betasatellite and an alphasatellite were isolated The complete nucleotide sequence of the Begomovirus showed the arrangement of genes typical of Old World begomoviruses with the highest nucleotide sequence identity 99 to an isolate of Ageratum yellow vein virus AYVV confirming it as an isolate of AYVV The complete nucleotide sequence of betasatellite showed greater than 89 nucleotide sequence identity to an isolate of Tomato leaf curl Java betasatellite originating from Indonesian The sequence of the alphasatellite displayed 92 nucleotide sequence identity to Sida yellow vein China alphasatellite This is the first identification of these components in Nepal and the first time they have been identified in papayaThis research was partly supported by an Advanced Research Project of the Nodai Research Institute Tokyo University of Agriculture Japan RWB is supported by the Higher Education Commission Govt of Pakistan under the “Foreign Faculty Hiring Program” The authors are also grateful to Mr B J Pudashini to help in collecting samples
