Revisiting ethylene metabolism: Identification of an ethylene glycol-glucose conjugate reveals active ethylene metabolism in Populus
Abstract In many plant species, the role of ethylene as a phytohormone signal has been well-studied, yet its direct metabolism in planta has received less attention. Consequently, this gap constrains our understanding of the full impact ethylene has on plant systems. During multiple evaluations of resilience in Populus spp., we detected an unidentified metabolite with plausible links to ethylene.
