Complete Genome Sequences of Peach Latent Mosaic Viroid from a Single Peach Cultivar
Peach latent mosaic viroid (PLMVd) is a member of the genus Pelamoviroid in the family Avsunviroidae and infects peach trees. We de novo assembled a PLMVd genome from a peach transcriptome and identified 18 variants in a single peach cultivar, after sequencing 20 PLMVd genomes by Sanger sequencing.
متن کاملStudy of the polymerization step of the rolling circle replication of peach latent mosaic viroid Brief Report
We have developed an in vitro transcriptional assay using Escherichia coli RNA polymerase to initiate the replication of peach latent mosaic viroid (PLMVd). Regardless of the polarity of the PLMVd strand used as template, initiation in vitro occurred at the same hairpin structure. These initiation sites correspond to the 5′-ends of two small (280 nt) PLMVd-related RNAs found in infected peach l...
متن کاملSequencing of peach latent mosaic viroid variants from nine North American peach cultivars shows that this RNA folds into a complex secondary structure.
We sequenced 34 new peach latent mosaic viroid (PLMVd) variants isolated from nine different peach cultivars. This study provides the widest view of PLMVd diversity reported to date and includes the original characterization of North American variants, which cannot be differentiated from European sequences. PLMVd appears as a species in which each isolate is a complex mixture of RNAs. Analysis ...
متن کاملXYLEM CHEMISTRY MEDIATION OF RESISTANCE TO PIERCE’S DISEASE Project Leader:
INTRODUCTION Xylella fastidiosa (Xf) is a Gram-negative xylem-limited bacterium that causes Pierce’s disease (PD), plum leaf scald, almond leaf scorch, phony peach disease and many other diseases. For many plant species there is no resistant germplasm. Xylem vessels may be filled with exopolysaccharides produced by the bacterium, and pectins, gums and tyloses produced by the plant. There has be...
متن کاملBacterial Leaf Scorch of Urban Trees
Bacterial leaf scorch is caused by Xylella fastidiosa Wells et al. The pathogen causes chronic leaf scorch and decline in elm, oak, sycamore, and maple. X. fastidiosa has a wide host range and is responsible for many other serious diseases including Pierce's disease of grape, phony disease of peach, and citrus variegated chlorosis. Its role in shade tree disorders has only recently been recogni...
