Additional file 1 of Co-application of biochar and melatonin enhances rice resilience to combined lead and microplastics stress via modulating antioxidant defense, hormonal regulation, gene expression, and soil quality

Summary

I'm not able to write an accurate summary here because the text provided is just a supplementary file placeholder ("Supplementary Material 1"), not the actual research content. The title suggests this study looked at whether adding biochar (a charcoal-like soil additive) and melatonin to soil can help rice plants better withstand pollution from lead and microplastics—both of which can end up in food and pose health concerns for people who eat contaminated crops. To write an accurate TLDR, I'd need the full abstract or paper text describing the actual methods and results. Could you share that content?
