Different rates of spontaneous mutation of chloroplastic and nuclear viroids as determined by high-fidelity ultra-deep sequencing
2017
[EN] Mutation rates vary by orders of magnitude across biological systems, being higher for simpler genomes. The simplest known genomes correspond to viroids, subviral plant replicons constituted by circular non-coding RNAs of few hundred bases. Previous work has revealed an extremely high mutation rate for chrysanthemum chlorotic mottle viroid, a chloroplastreplicating viroid. However, whether this is a general feature of viroids remains unclear. Here, we have used high-fidelity ultra-deep sequencing to determine the mutation rate in a common host (eggplant) of two viroids, each representative of one family: the chloroplastic eggplant latent viroid (ELVd, Avsunviroidae) and the nuclear pot…
First report of Cucumber mosaic virus infecting Solanum jasminoides in Italy
2008
Solanum jasminoides Paxton (potato vine or jasmine nightshade) is a vegetatively propagated ornamental species within the Solanaceae family. Recently, symptomless plants of this species were reported as natural hosts of the quarantine pest, Potato spindle tuber viroid (PSTVd) in Italy (1). In January 2008, approximately 1,000 potted, 2-year-old plants of S. jasminoides growing in an ornamental nursery in Sicily showed virus-like mosaic and malformation of leaves. Symptoms were observed on approximately 60% of the plants. Leaf tissue, collected from 30 symptomatic and 10 symptomless plants, was analyzed by double-antibody sandwich-ELISA with polyclonal antisera specific to Cucumber mosaic v…
