Van der Waals interactions involve instantaneous dipoles and induced dipoles that arise because of fluctuations in the electron charge distributions of adjacent nonbonded atoms.

Like ABA, strigolactones are derived from carotenoid precursors in plastids in a pathway that is conserved up to synthesis of the intermediate carlactone, beyond which strigolactone biosynthesis diverges in a species- specific manner

Strigolactone biosynthetic pathway and signaling proteins. All-trans-b-carotene is isomerized to 9-cis-b-carotene by a b-carotene isomerase. 9-cis-b-Carotene is cleaved by carotenoid cleavage dioxygenases, to produce carlactone. 

The final stages of strigolactone synthesis and signalling occur in the cytosol.

Strigolactones are perceived by a protein complex containing an a-/b-fold hydrolase protein and an F-box protein (D14 and MAX2, respectively)
