Plant, Cell &Environment, Volume 49, Issue 7, Page 3500-3517, July 2026.Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing
Advanced Science, Volume 13, Issue 33, 15 June 2026.Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial
