The cloned cDNA copies corresponding to 1300 nucleotides adjacent to the 3'‐terminal poly(A) tract of the potato virus X (PVX) genome have been sequenced. The amino acid sequences of three open reading frames were deduced from the nucleotide sequence. Two putative small nonstructural polypeptides corresponding to the open reading frames adjacent to the coat protein cistron possess some properties of membrane‐associated proteins. Direct sequence homology and common structural peculiarities exist between the PVX small proteins and the putative small nonstructural proteins encoded by RNA 2 of hordeiviruses and furoviruses
