Description
Wenting Liang and co-authors studied a plant hormone signal in a liverwort in 2024. Jasmonate hormones help plants handle pests, wounds, and stress. In early land plants such as liverworts, a form called dn-OPDA carries the signal, while most leafy plants use a different joined form.
After wounding, the liverwort made a previously unknown set of compounds: dn-OPDA joined to amino acids. The same joins appeared after insect feeding and in other species that use this signal form. Plants missing one joining enzyme could not make the compounds and showed a constantly active defense path and stronger pest resistance. Joining thus switches the hormone off in these plants, the reverse of its role in leafy plants.
