Article Synopsis
- A fungus causing severe leaf disease in flue-cured tobacco affects yield and quality in southwest China, prompting researchers to study its growth and metabolic traits.
- The study used traditional methods and Biolog Phenotype MicroArray, discovering the fungus's ability to metabolize various nutrient sources and adapt to different environmental conditions, with optimal growth at 25°C on specific media.
- Genome sequencing revealed 10,821 predicted genes, and analysis of the microflora on diseased leaves indicated poor metabolic capabilities, highlighting challenges for future research and potential strategies for disease management in tobacco cultivation.
is a destructive pathogen that frequently causes tobacco pole rot in curing chambers. Phenotypic characterization of the pathogen was conducted to provide basic biological and pathological information using Biolog Phenotype MicroArray (PM). In addition, the Y5 strain of was sequenced using Illumina HiSeq and Pacific Biosciences (PacBio) technologies.

- Tobacco plants in Guizhou, China, experienced significant damage from a disease called tobacco target spot, affecting 50% of plants in a commercial field as of July 2020.
- The disease showed initial symptoms as round, watery spots that grew larger and developed concentric rings before causing leaf death.
- Researchers isolated a fungus (designated as Isolate J136) and identified it as R. solani AG-6 using genetic analysis techniques, confirming its classification through specific PCR primers and sequencing.
Flue-cured tobacco (Nicotiana tabacum L.) is a leafy, annual, solanaceous plant grown commercially for its leaves in China. Around 70% of tobacco production in China occurs in southwest China.

A study was conducted from 2014 to 2017 to determine the relationship between the abundance of B. odoriphaga and temperature (atmospheric and soil), soil water content, and atmospheric humidity in a Chinese chive field in Beijing City, China.

Information on the effects of biotic and abiotic factors on the flight performance of B. odoriphaga is crucial for understanding the pest's ability to disperse and migrate.

The aim of this study was to assess the effects of AITC on the Bradysia odoriphaga Yang et Zhang (Diptera: Sciaridae) and the seeds and seedlings of the Chinese chive. Allyl isothiocyanate was toxic to all four developmental stages of B.
