“…The assembly resulted in 21 contigs totaling 751,949 bp with a G + C content of 27.31% ( Table 1 ) ( Figure 2 ). Recently, the draft genome of Phyllody Phytoplasma StrPh-CL (subgroup 16SrXIII-F) was reported, which has been implicated in causing strawberry phyllody in Chile [ 30 ]. The authors of this study assigned a genome completeness value of approximately 90% to StrPh-CL based on PFGE experiments.…”

“…None of the evaluated sequences showed ANI values higher than 95%. The phytoplasma strain StrPh-Cl (16SrXIIII-F) [ 30 ] exhibited the highest ANI value of 92.76% in the comparisons ( Table S5 ). These findings, combined with the species’ restricted geographical distribution and specific biological properties, provide further support for the taxonomic classification of ‘ Ca.…”

‘Candidatus Phytoplasma meliae’ is a pathogen associated with chinaberry yellowing disease, which has become a major phytosanitary problem for chinaberry forestry production in Argentina. Despite its economic impact, no genome information of this phytoplasma has been published, which has hindered its characterization at the genomic level. In this study, we used a metagenomics approach to analyze the draft genome of the ‘Ca. P. meliae’ strain ChTYXIII. The draft assembly consisted of twenty-one contigs with a total length of 751.949 bp, and annotation revealed 669 CDSs, 34 tRNAs, and 1 set of rRNA operons. The metabolic pathways analysis showed that ChTYXIII contains the complete core genes for glycolysis and a functional Sec system for protein translocation. Our phylogenomic analysis based on 133 single-copy genes and genome-to-genome metrics supports the classification as unique ‘Ca. P. species’ within the MPV clade. We also identified 31 putative effectors, including a homolog to SAP11 and others that have only been described in this pathogen. Our ortholog analysis revealed 37 PMU core genes in the genome of ‘Ca. P. meliae’ ChTYXIII, leading to the identification of 2 intact PMUs. Our work provides important genomic information for ‘Ca. P. meliae’ and others phytoplasmas for the 16SrXIII (MPV) group.

Phytoplasma-associated diseases are mainly insect-transmitted and are present worldwide. Considering that disease detection is a relevant environmental factor that may elucidate the presence of these diseases, a review reporting the geographic distribution of phytoplasma taxa in geographically consistent areas helps manage diseases appropriately and reduce their spreading. This work summarizes the data available about the identification of the phytoplasma associated with several diverse diseases in South America in the last decades. The insect vectors and putative vectors together with the plant host range of these phytoplasmas are also summarized. Overall, 16 ‘Candidatus Phytoplasma’ species were detected, and those most frequently detected in agricultural-relevant crops such as corn, alfalfa, grapevine, and other horticultural species are ‘Ca. P. pruni’, ‘Ca. P. asteris’, and ‘Ca. P. fraxini’.
