The Role of Trans-2-hexenal in Plant Defense Responses

doi:10.11983/CBB20131

Abstract

Abstract: As a small molecule volatile compound released by green plants, trans-2-hexenal plays a vital role in regulating plant growth and resistance to various environmental stresses. Studies have shown that trans-2-hexenal exhibits obvious inhibition on growth of plant root, and defense against bacterial infection and herbivorous feeding. Furthermore, it also displays a ‘messenger’ role in transmitting defense signals among plants. This paper reviewed trans-2-hexenal biosynthesis, metabolism pathway and its important role in defense response to biotic stress, also discussed the current problems in this research field and suggestions for future research, which would be helpful to illustrate defense or growth mechanism in plant response to trans-2-hexenal.

Key words: green leaf volatiles, plant defense response, trans-2-hexenal
