  abstract = {{W}e analyzed the production of reactive oxygen species, the accumulation of salicylic acid ({SA}), and peroxidase activity during the incompatible interaction between cotyledons of the cotton (#{G}ossypium hirsutum$) cv {R}eba {B}50/#{X}anthomonas campestris$ pv #malvacearum$ ({X}cm) race 18. {SA} was detected in petioles of cotyledons 6 h after infection and 24 h post inoculation in cotyledons and untreated leaves. {T}he first peak of {SA} occurred 3 h after generation of superoxyde ({O}2-), and was inhibited by infiltration of catalase. {P}eroxidase activity and accumulation of {SA} increased in petioles of cotyledons and leaves following {H}2{O}2 infiltration of cotyledons from 0.85 to 1m{M}. {I}nfiltration of 2 m{M} {SA} increased peroxidase activity in treated cotyledons and in the first leaves, but most of the infiltrated {SA} was rapidly conjugated within the cotyledons. {W}hen increasing concentrations of {SA} were infiltrated 2.5 h post inoculation at the beginning of the oxidative burst, the activity of the apoplastic cationic {O}2(sup .-)-generating peroxidase decreased in a dose-dependent manner. {W}e have shown that during the cotton hypersensitive response to {X}cm, {H}2{O}2 is required for local and systemic accumulation of {SA}, which may locally control the generation of {O}2(sup . -). {D}etaching cotyledons at intervals after inoculation demonstrated that the signal leading to systemic accumulation of {SA} was emitted around 3 h post inoculation, and was associated with the oxidative burst. {SA} produced 6 h post infection at {HR} sites was not the primary mobile signal diffusing systemically from infected cotyledons.
