Soil drench with zoospore suspension of P. nicotianae or BABA primes
C. annuum foliar defense responses
Production of autofluorescent compounds was evaluated in plants treated with P. nicotianae at
24 h post foliar inoculation with P. capsici. Confined autofluorescence in epidermal and mesophyll
cells was observed, typically in close proximity to stomatal openings (data not shown).
The hydrogen peroxide indicator stain 3-diaminobenzidine (DAB) was used to visualize
