“…The glycoside spectrum in tomatoes is in harmony with anabolic and catabolic processes. 32 Among the many induced compounds by FSF, the number of flavonoid glycosides is the largest (Figure 5C). Flavonols can capture ROS in vitro, such as H 2 O 2 , and its capture rate is comparable to that of ascorbic acid.…”

“…31 Glycosides have many assumed biological effects in plants, including photoprotection, regulation of hormone translocation, and isolation of ROS. 32 FSF stress caused the fluctuation of glycoside levels in tomato (Figure 5C). It has been reported that abiotic stress leads to an increase in the level of flavonol glycosides, a decrease in chlorophyll, and the change in the phenol content in chlorotic plant tissues.…”

“…Flavonols can capture ROS in vitro, such as H 2 O 2 , and its capture rate is comparable to that of ascorbic acid. 32 Flavonol glycosides capture ROS in a nonenzymatic manner. 32 Under FSF stress, the increase in the content of precursor compounds (phenylalanine, cinnamic acid, and coumaroyl acid) for the synthesis of flavonols is conducive to the production of more flavonols (Figures 6 and 7).…”

Taking kaempferol and quercetin as examples, the content of quercetin was down-regulated under FSF stress and more quercetin glycosides were produced (Figure 6).…”

Fluensulfone (FSF) becomes increasingly popular because of its nonfumigation application method. However, studies on the metabolic mechanism of FSF in plants are lacking. Here, tomato seedling was cultivated in hydroponic media to investigate the connection among FSF’s metabolism in tomato, the regulation of tomato endogenous glycosides, and the elimination of hydrogen peroxide in tomato cells. The accumulation of FSF was only detected in the lower stems of tomatoes; FSF was mainly metabolized into S-glycosylated conjugates in the roots, and the roots were the tissues with the highest metabolite content; and no FSF and metabolites were detected in the upper leaves. In response to FSF stress (2 mg/L for 7 d), the content of sugar and glycosides in the stems of tomato seedlings significantly increased. The amount of some compounds on the pathway related to glucose was affected by FSF. The three precursor compounds (homomethioine, isoleucine, and l-tyrosine) in the pathway of glucosinolate biosynthesis increased significantly under the stress of FSF, which indicates that FSF may compete with them for UGT74B1. Besides, FSF-induced flavonoid glycosides may play a role in the process of removing hydrogen peroxide. This research provides inspiration for the fate of many xenobiotics containing sulfonyl groups in plants.

“…l -Rha, on the other hand, is less abundant in animals but widely present in plants and bacteria. In plants l -Rha can be found in the primary and secondary cell wall in the sugar polymer pectin and also as a sugar moiety on glycosylated flavonoids ( 11 , 18 , 21 , 22 ).…”
