This research explores how beneficial fungi living inside plants can help protect them from harmful microorganisms and expand their chemical diversity. Using an advanced chemical analysis technique (HPTLC), researchers showed how these friendly fungi can either directly fight off harmful organisms or help transform plant compounds into protective substances. Impacts on everyday life: • Better understanding of natural plant defense systems could lead to more sustainable crop protection • Could help develop new natural alternatives to synthetic pesticides • May lead to discovery of new beneficial compounds for medicine and agriculture • Demonstrates potential for improving plant health through managing beneficial microorganisms • Could contribute to more environmentally-friendly farming practices
