Strigolactones (SLs) are recently identified plant hormones modulating root and shoot branching. Besides their endogenous role within the producing organism, SLs are also key molecules in the communication of plants with arbuscular mycorrhizal (AM) fungi and parasitic weeds. In spite of the crucial and multifaceted biological role of SLs, THERE IS NO INFORMATION ON THE RECEPTOR(S) WHICH BIND(S) SUCH ACTIVE MOLECULES, neither in the producing plants, nor in parasitic weeds or AM fungi. IN ORDER TO SUPPORT THE HYPOTHESIS THAT D14 COULD BE AN endogenous SLs receptor, WE PERFORMED docking experiments WITH natural and synthetic SLs analogues.We used the same set of compounds used by Akiyama et al 3 to compute the docking energy and pose in D14 as the plant receptor of SL.  Read More ..
