The resulting genome is 6667-nt long and encodes five open reading frames in an arrangement typical of other potexviruses. This virus appears to be a novel member within the genus <i>Potexvirus</i>. Blast analysis of <i>RNA-dependent RNA polymerase</i> (RdRp) and <i>coat protein</i> (CP) genes showed the highest amino acid sequence identity (67% and 71%, respectively) with pitaya virus X. Based on nucleotide sequence similarity and phylogenetic analysis, the name papaya virus X is proposed for this newly characterized potexvirus that was mechanically transmitted to papaya plants causing chlorotic patches and severe mosaic symptVirusesAn Unwanted Association: The Threat to Papaya Crops by a Novel Potexvirus in Northwest Argentina.PMC9610017PROY\INV\CCBIO\2021\3150PICT 2020-02868I090Badaracco ABejerman NQuito-Avila DCabrera Mederos DDebat HFlores CSanchez-Rodriguez AOrtiz CPortal ONome CJaramillo Zapata MTorres CAcuna LGiolitti FCastellanos Collazo OTrucco VfalseAn Unwanted Association: The Threat to Papaya Crops by a Novel Potexvirus in Northwest Argentina.An emerging virus isolated from papaya (<i>Carica papaya</i>) crops in northwestern (NW) Argentina was sequenced and characterized using next-generation sequencing.
