Advances in the metabolism and phytoremediation of pesticides in horticultural plants.

Horticultural plants necessitate the use of pesticides. However, inappropriate application may lead to excessive residue in the product organs, thereby undermining food safety and polluting the environment. Pesticides can be absorbed by the leaves, roots, fruits, and seeds of horticultural plants, followed by local accumulation or translocation to other parts. Horticultural plants possess the ability to process pesticides through cellular metabolism and detoxification mechanisms. Metabolomics provides novel perspectives on the impacts of horticultural plants' responses to pesticides, the quality of horticultural plants influenced by pesticides, and the metabolic pathways of pesticides within horticultural plants. Hormones, exogenous chemicals, endophytes, and rhizosphere microbes all play integral roles in the metabolism of pesticides in horticultural plants. These findings underpin the development of strategies aimed at obtaining horticultural products with reduced pesticide residues. Moreover, horticultural plants are particularly well-suited for the phytoremediation of pesticide-contaminated environments, a process that can be executed efficiently and cost-effectively. This review focuses on recent advancements in pesticide metabolism and phytoremediation in horticultural plants. It presents insights that contribute to the reduction of pesticide residues in horticultural products and the environment, thus safeguarding human health and promoting sustainable development.
