sp. nov.: a peach-colored actinobacterium isolated from symptomless tomato plant.

Article Synopsis
- In 2015, researchers identified peach-colored actinobacterial strains from healthy tomato plants in Iran, which are non-pathogenic and distinct from known tomato pathogens.
- The strains were found to belong to a new species based on biochemical tests and advanced genetic analysis, confirming they are different from all previously described species.
- The study formally proposes the name *[new species name not provided]* sp. nov. for these strains, with one strain designated as the type strain.
Bacterial ring rot of potato caused by Clavibacter sepedonicus: A successful example of defeating the enemy under international regulations.

Background: Bacterial ring rot of potato (Solanum tuberosum) caused by the gram-positive coryneform bacterium Clavibacter sepedonicus is an important quarantine disease threatening the potato industry around the globe. Since its original description in 1906 in Germany, management of ring rot has been a major problem due to the seedborne nature (via seed tubers not true seeds) of the pathogen allowing the bacterium to be transmitted long distances via infected tubers.
Disease Symptoms: On growing potato plants: interveinal chlorosis on leaflets leading to necrotic areas and systemic wilt.
Molecular Analysis of Bacterial Isolates From Necrotic Wheat Leaf Lesions Caused by , and Description of Three Putative Novel Species, sp. nov., sp. nov. and sp. nov.

Article Synopsis
- - The study focused on isolating bacterial strains from wheat leaf tissues affected by BLS disease, using nutrient agar instead of the common semi-selective medium, which led to the discovery of 49 strains across 10 genera.
- - Using advanced techniques like phylogenetic analysis and multilocus sequence analysis (MLSA), five strains were identified as novel species, contributing to our understanding of bacteria involved in wheat diseases.
- - Comparative genomics showed these novel species have unique genetic traits, including special secretion systems and potential antibiotic production, as well as CRISPR-Cas systems that might help them resist foreign genetic elements.

is a Gram-stain-positive bacterium with eight subspecies, five of which have been redefined as different species on the basis of their genome sequence data. On the basis of the results of phylogenetic analysis of gene sequences, strains of members of the genus isolated from barley have been grouped in a separate clade from other species and subspecies of the genus . In this study, the biochemical, physiological, fatty acids and genetic characteristics of strains DM1 and DM3, which represented the barley isolates, were examined.
