Plants use an array of secondary metabolites to defend themselves
against harmful organisms and to attract others that are beneficial.
However, the attraction of beneficial organisms could also lead to
abuse by malevolent organisms. An exciting example of such abuse is the
relationship between plants, beneficial mutualistic arbuscular
mycorrhizal fungi and harmful parasitic plants. Signalling molecules
called strigolactones, which are secreted by plant roots in low
concentrations, induce the growth of both obligate biotrophs. Here, we
review the importance of strigolactones for these two interactions and
discuss possible developments that should further clarify the role of
these signalling molecules in rhizosphere processes.
