The detection of chloramphenicol (CAP) is of paramount importance in safeguarding food safety and protecting human health. Herein, a photochemical (PEC) electrode combined with CAP molecular imprinted (TiO 2 -MIPC) films has been reported and then the PEC property has been utilized to realize light-elution function. The PEC theory has been used to accelerate the preparation of MIPs combined with special recognition of MIPs to enhance PEC sensors and their detection capacity. The SEM image shows that MIP films were deposited on a pipe orifice of the TiO 2 . The TiO 2 -MIPC sensor electrode exhibits high selectivity and sensitivity for determination of CAP, and the differential pulse voltammetry (DPV) analysis is highly linear over CAP concentrations of 0.1−20 ng/mL with a detection limit of 0.03 ng/mL (S/N = 3). Moreover, DFT calculations indicate that the combination mode of PANI@CAP may be hydrogen-bond interactions between amino and nitro groups, and the P/N junction of PEC-MIPC generates photogenic charge to break the hydrogen bond as well promote the self-elution function. Thus, this convenient and sensitive PEC sensor will improve the efficiency of hazardous substance detection and offer a design for future PEC sensors.

Auxin-Induced SaARF4 Downregulates SaACO4 to Inhibit Lateral Root Formation in Sedum alfredii Hance

Lateral root (LR) formation promotes plant resistance, whereas high-level ethylene induced by abiotic stress will inhibit LR emergence. Considering that local auxin accumulation is a precondition for LR generation, auxin-induced genes inhibiting ethylene synthesis may thus be important for LR development. Here, we found that auxin response factor 4 (SaARF4) in Sedum alfredii Hance could be induced by auxin. The overexpression of SaARF4 decreased the LR number and reduced the vessel diameters. Meanwhile, the auxin distribution mode was altered in the root tips and PIN expression was also decreased in the overexpressed lines compared with the wild-type (WT) plants. The overexpression of SaARF4 could reduce ethylene synthesis, and thus, the repression of ethylene production decreased the LR number of WT and reduced PIN expression in the roots. Furthermore, the quantitative real-time PCR, chromatin immunoprecipitation sequencing, yeast one-hybrid, and dual-luciferase assay results showed that SaARF4 could bind the promoter of 1-aminocyclopropane-1-carboxylate oxidase 4 (SaACO4), associated with ethylene biosynthesis, and could downregulate its expression. Therefore, we concluded that SaARF4 induced by auxin can inhibit ethylene biosynthesis by repressing SaACO4 expression, and this process may affect auxin transport to delay LR development.
