i.e. SHLF, two-step synthesis of a long-wavelength latent fluorogenic substrate SHLF. In the presence of NADH and under aerobic conditions, SHL catalyzes the decarboxylative hydroxylation of SHLF followed by a quinonemethide-type rearrangement reaction concomitant with the ejection of a fluorescence coumarin 2, which is spontaneous and irreversible at physiological temperatures in aqueous media. The fluorescence signal generated by this process is specific and, in the near red spectral region with an emission maximum at 595 nm, is suppressed by salicylic acid

additional information
-
construction of transgenic plants, using wild-type Columbia(0) plants and sid2 mutant plants, overexpressing the bacterial NahG, germination of NahG transgenic plants is influenced to a lesser degree by high salinity. Catechol accumulates in the transgenic plants and acts as an antioxidant that compromises the inhibitory effects of high salinity. Salicylic acid promotes seed germination under high salinity by modulating antioxidant activity in transgenic Arabidopsis thaliana, detailed overview
