Life?strategy evolution and the species survival in plants

현유봉 박사 (Max Planck Institute, Germany)

Plant species display extreme diversity in life?strategies that involves the variation in growth and development of shoot system. In this talk, I will discuss the divergence of annual and perennial life?history in plants on the basis of reproductive patterns on the shoot. Furthermore, my talk will present a quick tour of the range of variation in shoot function that enables the plant species to survive during their divergence under natural selection.
