CJAN1179 auxin production via a tryptophan-depended (TD) mechanism is much higher than by tryptophan-independent (TI) mechanism concluded by current work and displayed in straight line. As described for other fungi, it might be that auxin production by the plant is stimulated by fungal volatiles. This putative fungus–plant interaction signalling is displayed in dotted lines and has been proposed for future work. CJAN1179 might produce certain volatiles such as ethylene, jasmonate and sesquiterpenes (SQTs) that activate plant auxin biosynthesis genes. Both auxin production mechanisms are likely involved in enhancing lateral root and root hair formation in A. thaliana. Model adopted and
