Evolution of a Novel and Adaptive Floral Scent in Wild Tobacco.

Han Guo et al.

Molecular biology and evolution, 37(4), 1090-1099 (2019-12-07)

Many plants emit diverse floral scents that mediate plant-environment interactions and attain reproductive success. However, how plants evolve novel and adaptive biosynthetic pathways for floral volatiles remains unclear. Here, we show that in the wild tobacco, Nicotiana attenuata, a dominant
