A novel function of sanshools: The alleviation of injury from metolachlor in rice seedlings
چکیده انگلیسی


• Sanshools are prepared from Szechuan pepper by SFE, identified and quantified using HPLC and ESI-MS.
• Sanshools effectively alleviate the injury from metolachlor in rice seedlings.
• Sanshools trigger GST and up-regulate four GST encoded genes in rice seedlings exposed to metolachlor.
• Sanshools possess great potential for application to the safening of crops such as rice.

Szechuan peppers are extensively used as a spice and in traditional medicine in Asia, primarily because of its active compounds, sanshools (S). However, there is only limited mention in agriculture, and there are no papers reporting its use as an herbicide safener. In this study, we provide the first evidence that S can effectively alleviate rice-seedling injury from metolachlor (M). We observed that the M-treated (0.25 μM) rice seedlings, which were 56.0%, 66.0%, and 57.0% of the non-treated control in shoot height, root length, and fresh biomass, respectively, were recovered by S to 93.1%, 97.6%, and 94.8%, respectively. The emergence rate was enhanced to over 80% in the M+S treatment, whereas it was below 60% in the M treatment. This M+S mixture elevated the rice-seedling root activity to higher than 87.0% of the value for the non-treated control. The activity of glutathione transferases in the combined treatments approximately doubles that of the M treatment and quadruples that of the non-treated controls. This effect was positively correlated with the induced expression of OsGSTU3. Our results suggest that S may represent a new group of safeners and enable the possibility of using these compounds for improving plant production or protecting rice from the phytotoxicity of metolachlor.
