The University of Macau (UM) held a talk titled ‘Natural Defense Shield: Deciphering the Two-component Chemical Defense System of Panax Plants’ as the 19th UM Scholar Research Forum. Wan Jianbo, professor and programme coordinator at the Institute of Chinese Medical Sciences and the State Key Laboratory of Quality Research in Chinese Medicine, was the speaker. The talk was well attended by faculty members and students.

During the talk, Prof Zhou first presented the efficacy, geographical distribution and chemical composition of Chinese medicine Panax notoginseng. He also explained how he discovered the two-component chemical defence system in the leaves of Panax notoginseng, which contributes to our understanding of how Panax plants resist pathogen invasion and provides insights into the development of green pesticides.
