Abstract: Isoprene is the main component of numerous volatile hydrocarbons emitted by vegetation. Its biosynthesis and e-mission from vegetation plays an important role in global carbon balance, greenhouse effect, and atmospheric pollution. In this paper, the main factors determining isoprene emission rate, isoprene emission amount and its calculation methods, as well as its potential ecological functions were reviewed. The importance of further study on the relationships between multiple stresses and isoprene biosynthesis and emission was emphasized.

Key words: Isoprene, Plant emission, Environmental stress, Ecological significance
