چکیده انگلیسی
Nitric oxide (NO) and mitogen-activated protein kinase (MPK) play important roles in brassinosteroid (BR)-induced stress tolerance, however, their functions in BR-induced pesticides metabolism remain unclear. Here, we showed that MPK activity and transcripts of SlMPK1 and SlMPK2 were induced by chlorothalonil (CHT), a widely used fungicide, in tomato leaves. However, cosilencing of SlMPK1/2 compromised the 24-epibrassinolide (EBR)-induced upregulation of detoxification genes and CHT metabolism in tomato leaves. In addition, cosilencing of SlMPK1/2 inhibited the accumulation of S-nitrosothiol (SNO), the reservoir of nitric oxide (NO) in plants, whereas tungstate, the inhibitor of nitrate reductase (NR), blocked EBR-induced SNO accumulation and MPK activity. Inhibiting the accumulation of NO by cPTIO, the specific scavenger and tungstate abolished the EBR-induced upregulation of detoxification genes, glutathione accumulation and CHT metabolism. The results showed that MPK and NR-dependent NO were involved in BR-induced CHT metabolism. Notably, there was a positive crosstalk between the MPK and NO production.
