摘要: Selenium (Se) mitigates heavy metal(loid) toxicity in plants, however, its regulatory effects on photosynthesis and metabolic pathways remain poorly understood. This study investigated the alleviating effects of selenite on cadmium (Cd), lead (Pb), and antimony (Sb) toxicity across three varieties of Brassica campestris L. (V1, V2 and V4) and one Orychophragmus violaceus L. (V3) using physiological, biochemical, and metabolomic approaches. Results revealed variety-dependent mechanisms of Se-mediated detoxification: in resistant varieties (V1), although Se stimulated photosynthetic efficiency (Pn) but inhibited the abundance of most tested fatty acid and terpenes/terpenoids, and induced energy dissipation and exacerbated electron transfer. In addition, Se stimu-lated purine metabolism, pyrimidine metabolism, phenylpropanoid biosynthesis, and the formation of some flavonoid/flavones. But Se reduced the metabolism of galactose and histidine, and jasmonate formation. Whereas in the sensitive cabbage-type rapeseed (V4), Se rebalanced photosynthetic electron transfer but did not signifi-cantly affect Pn. Additionally, Se upregulated the abundance of terpenoids (e.g., gibberellins, abscisic acid), oligopeptides, and DEMs involved in galactose metabolism. But Se restricted the salicylate synthesis, toluene degradation, and the metabolism of purine and histidine. These findings elucidate that the detoxification mechanisms of multiple metal(loid) by Se may be plant variety-dependent
