However, upon infection with the Gram-negative bacterium Erwinia carotovora carotovora 15 (Ecc15), Dpt expression was significantly increased beyond wild type levels after 8 h of infection in dRYBP1and dRYBPΔ55 homozygous mutant flies, as well as in flies of dRYBP1 or dRYBPΔ55 genotype over dRYBP genomic deficiencies excluding background effects (Fig. 1A, 8 hours). The gene discussed is DPT; the disease is infection.
