A host shift as the origin of tomato bacterial canker caused by .

The Actinomycetota (formerly Actinobacteria) genus includes phytopathogens with devasting effects in several crops. , the causal agent of tomato bacterial canker, is the most notorious species of the genus. Yet, its origin and natural reservoirs remain elusive, and its populations show pathogenicity profiles with unpredictable plant disease outcomes.

Analysis of Bacterial Microbiota of Aerated Compost Teas and Effect on Tomato Growth.

Mature composts and their water-based extracts, known as aerated compost teas (ACTs), are biofertilizers that share bioactive effects like soil restoration and plant health promotion, widely used for sustainable agriculture. Bioactive effects of compost and ACTs could be associated with their physicochemical and biological characteristics, like carbon/nitrogen (C/N) ratio and microbiota structure respectively. In our study, we elaborated ACTs using mature homemade compost, wheat bran, and grass clippings, following the C/N ratio criteria.

Genome analysis of Pseudomonas sp. 14A reveals metabolic capabilities to support epiphytic behavior.

The surface of aboveground plant parts, known as the phyllosphere, is a habitat for various microorganisms called epiphytes establishing biotrophic interactions with their hosts. However, these communities can be affected by environmental and anthropogenic variations such as the application of agrochemicals. Thus, epiphytes have the capacity to survive in such environments.

Raman Spectroscopy and Machine-Learning for Early Detection of Bacterial Canker of Tomato: The Asymptomatic Disease Condition.

Bacterial canker of tomato is caused by subsp. (Cmm). The disease is highly destructive, because it produces latent asymptomatic infections that favor contagion rates.

Detection of subsp. Assisted by Micro-Raman Spectroscopy under Laboratory Conditions.

subsp. () is a quarantine-worthy pest in México. The implementation and validation of new technologies is necessary to reduce the time for bacterial detection in laboratory conditions and Raman spectroscopy is an ambitious technology that has all of the features needed to characterize and identify bacteria.
