Sulfane sulfur species are an important type of reactive sulfur species. These compounds have unique reactivity to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biol. systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes of hydrogen sulfide (H2S). The development of probes for selective, rapid, and sensitive detection of sulfane sulfur is of great significance for studying their physiol. and pathol. roles in biol. systems, especially in plant systems for which physiol. research has lagged behind. However, so far there is still a lack of sufficient chem. tools for directly tracking and measuring sulfane sulfur in biol. systems, and in particular, the detection of sulfane sulfur in living plant tissues is still challenging. Herein, the authors report a near-IR fluorescent probe, SSNIP, for the selective imaging of sulfane sulfur. SSNIP is capable of detecting sulfane sulfur at physiol. concentrations in both aqueous buffer and living human cells. Then, with SSNIP, the authors demonstrate the fluorescent monitoring of endogenous sulfane sulfur in plant tissues such as Arabidopsis thaliana roots for the first time. Furthermore, the application of SSNIP in evaluating the level of sulfane sulfur in Arabidopsis thaliana roots at different growth stages is performed. The results show that the level of sulfane sulfur in Arabidopsis thaliana roots correlates well with their growth stages, which suggests that sulfane sulfurs might act as actual signaling mols. to promote plant growth and root elongation. In addition, it reveals potential applications for the biol. and pathol. studies of sulfane sulfur, especially in plant physiol.
