摘要：

The coat protein (CP) sequences of eleven Papaya ringspot virus ( PRSV) isolates originating from different locations in India were determined, analysed and compared with the sequences of other isolates of PRSV. The virus isolates from India exhibited considerable heterogeneity in the CP sequences. The CP-coding region varied in size from 840 - 858 nucleotides, encoding protein of 280 - 286 amino acids. Comparative sequence analysis revealed that the PRSV isolates originating from India were divergent up to 11%. Though the PRSV isolates were differentiated in to two clusters, yet the sequence variation could not be correlated with the geographical origin of the isolates. Implication of the sequence variation in the coat protein derived transgenic resistance in papaya is discussed.
