(Z)-γ-bisabolene synthase (EC 4.2.3.40) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase ((Z)-γ-bisabolene-forming).{{cite journal | vauthors = Ro DK, Ehlting J, Keeling CI, Lin R, Mattheus N, Bohlmann J | title = Microarray expression profiling and functional characterization of AtTPS genes: duplicated Arabidopsis thaliana sesquiterpene synthase genes At4g13280 and At4g13300 encode root-specific and wound-inducible (Z)-gamma-bisabolene synthases | journal = Archives of Biochemistry and Biophysics | volume = 448 | issue = 1–2 | pages = 104–16 | date = April 2006 | pmid = 16297850 | doi = 10.1016/j.abb.2005.09.019 }} This enzyme catalyses the following chemical reaction

: (2E,6E)-farnesyl-diphosphate diphosphate $\backslash rightleftharpoons$ (Z)-γ-bisabolene + diphosphate

This enzyme is expressed in the root, hydathodes and stigma of the plant Arabidopsis thaliana.
