RAF-like protein kinases mediate a deeply conserved, rapid auxin response

The definition of a phytohormone has not always been clear, though most plant biologists agree that phytohormones can be defined as endogenous molecules capable of triggering signaling cascades and associated responses by binding to specific receptors. They have been extensively studied in flowering…

The main oxidative inactivation pathway of the plant hormone auxin (Nature Comms.)

Auxin is a key hormone in almost all stages of the plant development and its main natural form is  indole-3-acetic acid (IAA). In Arabidopsis, several gene families are involved in auxin homeostasis. In this work, Hayashi et al. focus on the roles of DIOXYGENASE FOR AUXIN OXIDATION 1 (DAO1) which converts…
