MicroRNA399 (miR399), a phosphate (Pi) starvation‐induced long‐distance signal, is first produced in shoots and moves to roots to suppress PHO2 encoding a ubiquitin conjugase, leading to enhanced Pi uptake and root‐to‐shoot translocation. However, the molecular mechanism underlying miR399 long‐distance movement remains elusive.

Artemisinin, a sesquiterpene compound synthesized and stored in the glandular trichome of Artemisia annua leaves, has been used to treat malaria. Previous studies have shown that both light and jasmonic acid (JA) can promote the biosynthesis of artemisinin, and the promotion of artemisinin by JA is dependent on light. However, the specific molecular mechanism remains unclear.
Here, we report a...
