Nature Communications 6: Article number: 6043 (2015); Published: 16 January 2015; Updated: 10 February 2016. It has come to our attention that the control version of the Jas9-VENUS reporter construct reported in this Article, mJas9-VENUS, which consists of a mutated version of Jas9 fused to VENUS, does not contain a nuclear localization signal as described in Fig.

Activated forms of jasmonic acid (JA) are central signals coordinating plant responses to stresses, yet tools to analyse their spatial and temporal distribution are lacking. Here we describe a JA perception biosensor termed Jas9-VENUS that allows the quantification of dynamic changes in JA distribution in response to stress with high spatiotemporal sensitivity. We show that Jas9-VENUS abundance is dependent on bioactive JA isoforms, the COI1 co-receptor, a functional Jas motif and proteasome activity. We demonstrate the utility of Jas9-VENUS to analyse responses to JA in planta at a cellular scale, both quantitatively and dynamically. This included using Jas9-VENUS to determine the cotyledon-to-root JA signal velocities on wounding, revealing two distinct phases of JA activity in the root. Our results demonstrate the value of developing quantitative sensors such as Jas9-VENUS to provide high-resolution spatiotemporal data about hormone distribution in response to plant abiotic and biotic stresses., Jasmonate regulates multiple aspects of plant growth, development and stress responses. Here, Larrieu et al. develop a fluorescent biosensor that allows jasmonate perception to be monitored at previously unobtainable levels of spatiotemporal resolution in Arabidopsis.
