Interference between variants of peach latent mosaic viroid reveals novel features of its fitness landscape: implications for detection

Natural populations of peach latent mosaic viroid (PLMVd) are complex mixtures of variants. During routine testing, TaqMan rtRT-PCR and RNA gel-blot hybridization produced discordant results with some PLMVd isolates. Analysis of the corresponding populations showed that they were exclusively compose...

description Natural populations of peach latent mosaic viroid (PLMVd) are complex mixtures of variants. During routine testing, TaqMan rtRT-PCR and RNA gel-blot hybridization produced discordant results with some PLMVd isolates. Analysis of the corresponding populations showed that they were exclusively composed of variants (of class II) with a structural domain different from that of the reference and many other variants (of class I) targeted by the TaqMan rtRT-PCR probe. Bioassays in peach revealed that a representative PLMVd variant of class II replicated without symptoms, generated a progeny with low nucleotide diversity, and, intriguingly, outcompeted a representative symptomatic variant of class I when co-inoculated in equimolecular amounts. A number of informative positions associated with the higher fitness of variants of class II have been identified, and novel sets of primers and probes for universal or specific TaqMan rtRT-PCR detection of PLMVd variants have been designed and tested.
