Abstract
Strigolactones (SLs) regulate plant growth and metabolism, but their concentration-dependent effects on leafy vegetable quality remain unclear. We investigated how the synthetic SL analog GR24 affects physiological and metabolic processes in pak choi (Brassica rapa subsp. chinensis). Mantel correlation analysis and partial least squares structural equation modeling (PLS-SEM) revealed distinct response patterns. The 1 μmol·L−1 treatment (T2) enhanced photosynthesis, carbon‑nitrogen assimilation, mineral accumulation, and GA3, ZT, ABA, and JA levels, whereas the 10 μmol·L−1 treatment (T3) promoted carotenoid and phenolic accumulation, including rutin, ferulic acid, and caffeic acid. Multivariate analysis linked phenolic acid accumulation mainly to nitrogen and amino acid metabolism, with additional associations with P status. Overall, T2 broadly enhanced primary metabolism and nutrition, whereas T3 favored secondary and antioxidant-related metabolism, providing a framework for optimizing GR24 application in high-quality leafy vegetable production.
It is demonstrated that GR24 delays postharvest senescence by alleviating water imbalance, enhancing antioxidant capacity, with transcriptomic evidence suggesting the involvement of phenylpropanoid biosynthesis-related genes and other critical genes.

While carbon dots (CDs) are promising green nanomaterials for sustainable agriculture, how they regulate cotton growth via physiological and metabolic reprogramming remains poorly understood. This study evaluated foliar CD application (0–200 mg·L−1) to uncover dose–response patterns and metabolic drivers. CDs exerted a...
Developing non-thermal technologies to enhance health-promoting compounds is important for producing high-value functional foods. This study compared the effects of electron beam irradiation (EBI) applied to dry broccoli seeds before germination (FZZZ) with those of direct irradiation of sprouts (FZYM) on glucosinolate...
