  • Cytokinin receptors predominantly localize to the endoplasmic reticulum. Here, Kubiasová et al. use a cytokinin fluoroprobe to show that ER-localized cytokinin receptors can enter the secretory pathway, reach the plasma membrane and undergo vesicular recycling, suggesting multiple sites of cytokinin perception.

  • Lateral root development is dependent on precise control of the distribution of the plant hormone auxin. Here Chen et al. propose the transcription factors ARF7 and FLP participate in a feed forward motif to mediate expression of the auxin transporter PIN3and consequently regulate lateral root development.

  • The concerted action of the hormones cytokinin and auxin is an important regulator of plant development. Here Šimášková et al. propose a mechanistic basis by which cytokinin-responsive transcription factors regulate transport of auxin in Arabidopsisroots.

  • It is unknown how plant cell polarities are connected to organismal axes. A SOSEKI protein is found to integrate apical–basal and radial organismal axes to localize to polar cell edges independent of tissue context, but requiring cell wall integrity.

  • 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.
