Tipping the Balance: Sclerotinia sclerotiorum Secreted Oxalic Acid Suppresses Host Defenses by Manipulating the Host Redox Environment
Figure 5
Oxalic acid induces reducing conditions that correlates with the dampening of the host oxidative burst.
Detached leaves of roGFP plants were infiltrated with either H2O or 10 mM KOA buffered to pH 7, and were examined for GFP fluorescence (Top two panels) over a time-course (0, 3, 6, and 12 hours). The same leaves were also stained for superoxide production (Bottom two panels) with nitro-blue tetrazolium (NBT).
