  • Peng et al. identify a class of non-aromatic, chorismate-derived compounds, abundant in the roots of Arabidopsis thaliana. These compounds are made by a biosynthetic gene cluster comprising five adjacent genes encoding biosynthetic enzymes.

  • Defects in the Casparian strip, a fine band of lignin that seals root endodermal cells and plays roles in nutrient homeostasis, activate a signaling pathway leading to over-lignification. Here, the authors show that this process leads to the deposition of compensatory lignin that is chemically distinct from Casparian strip lignin.

  • The plant hormone auxin is essential for plant development and growth and is transported across cellular membranes via specialized transporter proteins. In this study, Ranocha et al. identify the first vacuolar auxin transporter, WAT1, suggesting an involvement of the vacuole in auxin signalling.

  • Plants defend themselves against attackers by producing bioactive secondary metabolites such as triterpene saponins; here, the endoplasmic-reticulum-associated degradation (ERAD) system is shown to control the activity of HMGR, the rate-limiting enzyme in the supply of the terpene precursor isopentenyl diphosphate, thereby preventing unrestrained saponin production and ensuring the integrity of plant development.
