Improving the Comprehension of Pathogenicity and Phylogeny in ' Phytoplasma meliae' through Genome Characterization.

' 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 ' P.

First report of causing bacterial leaf streaks on wheat in Argentina.

Since 2018, bacterial-like symptoms, such as leaf streaks were observed on wheat plants ( L.) in Córdoba province in Argentina, with 1 to 5% of disease incidence. Samples of wheat stem and spike collected in a trial of varieties for summer/autumn sowing in the experimental field of the INTA Marcos Juárez were disinfected, washed and macerated in mortars with sterile distilled water and extracts were streaked on Luria-Bertani (LB) agar.

Draft Genome Sequence of " Phytoplasma pruni" (X-Disease Group, Subgroup 16SrIII-B) Strain ChTDIII from Argentina.

Herein, we report the draft genome sequence of " Phytoplasma pruni" strain ChTDIII (subgroup 16SrIII-B). The final assembly consists of 790,517 nucleotides organized in 67 contigs (minimal size, 1 kb), with a G+C content of 29.4% and encoding 672 proteins.

Mineral profile exploratory analysis for rice grains traceability.

Rice geographical traceability requires analytical procedures and data evaluation capable of linking its composition to the producing area. In this work, major and trace elements in soil and rice grains and husk from 9 cities and 17 producers were evaluated. Arsenic species were measured solely in rice grains.

Description of 'Candidatus Phytoplasma meliae', a phytoplasma associated with Chinaberry (Melia azedarach L.) yellowing in South America.

China tree yellows (ChTY) phytoplasma is associated with the yellowing disease of the China tree (Melia azedarach) in Argentina. According to partial 16S rRNA gene analysis, ChTY phytoplasma belongs to the 16Sr XIII group, subgroup G. Strains of species of ChTY have 98-99 % 16S rDNA gene sequence similarity with 16SrXIII-group phytoplasmas, and less than 97.
