A dedicated protein (a special elongation factor) named SELB in complex with GTP is required to deliver Sec–tRNASec to the ribosome. SELB ∙ GTP ∙ Sec–tRNASec reads the UGA codon as Sec rather than “Stop,” provided that the ribosomally bound

mRNA has a hairpin loop on the 3′ side of the UGA specifying Sec.

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.
