To further substantiate these indications and thus confirm the biological relevance of the transcriptomic signatures, we performed systemic bacterial infection experiments using Pectobacterium carotovorum (gram-negative bacteria, former name Erwinia carotovora carotovora) as a pathogen and Drosomycin-GFP (Drs-GFP) and Defensin-GFP (Def-GFP) reporter lines as readouts for increased expression of antimicrobial peptides40. The gene discussed is UTP25; the disease is bacterial infectious disease.
