Availability of mineral nutrients affects strigolactone (SL) production and exudation from plants. In legumes which form symbiotic relationship with root nodule bacteria, deficiency of phosphorus (P) but not other nutrients including nitrogen (N) significantly promoted SL production and exudation. By contrast, in non-legume plants, N deficiency as well as P deficiency increased SL exudation. Such a promotion of SL exudation under nutrient deficiency could be observed, in general, with mycotrophic plants but not with non-mycotrophic plants including Arabidopsis and white lupin.
