Salicylic acid is a member of benzoic acid derivatives, a group of compounds which have a backbone of C6C1 consisting of one carboxyl group and one (or more) hydroxyl group(s) attached to the aromatic ring. Salicylic acid is a signaling compound in systemic acquired resistance (SAR). An increased level of salicylic acid is found in the plant after a fungi's attack, which further induces the accumulation of phytoalexins, low molecular weight defense compounds.

The phytotoxic effect of cosmetics such as galaxolide (HHCB) has been investigated, however, their metabolic basis of this impact is still obscure. Thus, we investigated the effect of HHCB on the biomass accumulation, photosynthesis, primary and secondary metabolites in two species from different functional groups i.e.

The prevalence and persistence of phthalate esters (PAEs) in agricultural soils has garnered global attention. Assessing their potential impacts on crop yield and quality necessitates a thorough understanding of their risks. In this study, we elucidated the carbon flow-dependent mechanisms of the decreased grain quality upon exposure to PAEs through a soil-based rice cultivation experiment.

The selective oxidative cleavage and functionalization of C(OH)-C bonds in tertiary alcohols harbor immense feasibility in organic synthesis and enable the production of high value-added chemicals from renewable biomass. However, it remains a challenge, owing to the inherent kinetic inertness and thermodynamic stability of C(OH)-C bonds and the lack of C-H. Taking the huge potential and challenge of C(OH)-C bond activation and functionalization into consideration, herein, we show the first example of an inexpensive bifunctional ferric nitrate catalyst for catalytic direct oxidation of structurally distinct tertiary alcohols to esters with environmentally benign molecular oxygen as an oxidant and MeOH as a solvent, without the assistance of any additives.
