Ethylene independent functions of ACC in Marchantia polymorpha (Nature Plants)

Ethylene is synthesized from 1-Aminocyclopropane carboxylic acid (ACC), and ACC has long been used as a substitute to induce ethylene responses. In a new study, Li and colleagues show that ACC functions as a stand-alone signaling molecule in the liverwort Marchantia. While treatment with ethylene…

Ethylene signaling mediates host invasion by parasitic plants (Science Advances)

Parasitic plants cause agricultural devastation across the globe, yet the molecular basis of their parasitism is largely enigmatic. They grapple and intrude into the host roots with an organ called the haustorium. Haustoria formation is induced upon recognition of host-derived haustorium-inducing factors…

The sweet smell of sucrose transport during rose petal abscission
