Alignments of the 3′ NTR sequences of different potexviruses. Alignments were done by hand and were centered around hexanucleotide elements (in red) conserved among potexviruses. Additional potential hexanucleotide elements found upstream in CYMV, FXMV, PIAMV, and PMV sequences are also noted in red. The sequences aligned include our PVX strain,⁴⁹ bamboo mosaic virus (BaMV),⁸⁴ cymbidium mosaic virus (CyMV),⁸⁵ clover yellow mosaic virus (CYMV),⁸⁶ foxtail mosaic virus (FXMV),⁵² narcissus mosaic virus (NMV),⁸⁷ potato aucuba mosaic virus (PAMV),⁸⁸Plantago asiatica mosaic virus (PIAMV),⁸⁹ papaya mosaic virus (PMV),⁹⁰ strawberry mild yellow edge-associated virus (SMYEAV)⁹¹ and white clover mosaic virus (WClMV).⁹² Palindromic sequences are underlined on either side of the hexanucleotide elements. Similarities in the U-rich (blue) and putative NUE (yellow) sequences among the potexvirus RNAs are indicated.
