This video demonstrates the establishment of rice plant leaf infection through wounding inoculation with Magnaporthe grisea mycelium. The fungal spore-derived germ tube penetrates the epidermal layer, resulting in tissue infection and lesions on the leaves. This method aids pathotype screening and improves plant resistance understanding for molecular breeding.
Protocol
1. Fungal culture for M.grisea Prepare the oatmeal tomato agar (OTA) culture medium for fungal strains. Weigh 30 – 50 g of oatmeal, add this to 800 mL of distilled/deionized water (ddH2O), and boil the mixture for 30 min in the electric pot.
