WebHypaphorine, an indole alkaloid secreted by the fungus Pisolithus microcarpus during the formation of ectomycorrhizae with the host plant Eucalyptus globulus, inhibits root hair tip growth. Hypaphorine-induced inhibition is linked to a transient depolarization of the plasma membrane and a reorganization of the actin and microtubule cytoskeletons. WebHowever, we could not exclude the possibility that compound 4 could be a mixture of enantiomers. 2.2. Proposed Biosynthesis Pathway of 1–4 Based on the reported biogenesis of indole alkaloids from bacteria [11,13,35–38], we proposed the biosynthesis pathways of compounds 1–4 (Figure 2).
