Visualização de Twitching motilidade e Caracterização do papel da PilG in Xylella fastidiosa

Executive Industry Relevance

Functional characterization of bacterial motility regulators, such as PilG in Xylella fastidiosa, is critical for de-risking target selection in anti-infective discovery. Quantitative visualization of twitching motility using microfluidic imaging enables precise assessment of gene function and phenotypic outcomes. This approach strengthens predictive confidence in early-stage target validation and informs portfolio triage for plant pathogen intervention strategies.
