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.

Plants undergo morphological changes to enhance cooling at warm temperatures. Here Zhu et al. show that JOXs and ST2A enzymes, which mediate jasmonate catabolism, contribute to this process by reducing the level of bioactive jasmonate facilitating growth responses.
