     Orthologous strigolactone response mutants (max2/ore9 in Arabidopsis, rms4 in pea, d3 in rice) have been of major value to demonstrate the specificity of action of strigolactones (13, 22).

Azcón Aguilar, J. M. Barea, S. Gianinazzi, V. Gianinazzi-Pearson, editors, Mycorrhizas - Functional Processes and Ecological Impact, page 36:

     Strigolactones are produced by the non-mycorrhizal plant Arabidopsis thaliana (Westwood 2000; Goldwasser and Yoder 2001), and plant mutants defective for strigolactone production have not yet been obtained.

     The first strigolactone isolated from root exudates was strigol (Cook et al. 1966).
