🌿🔬 RESEARCH 🔬🌿 Using genetically encoded biosensors, we revealed the spatiotemporal dynamics of pattern-triggered immunity responses induced by different danger signals and by Pseudomonas syringae in Arabidopsis seedlings - Mor et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 1 (shortened, full legend in paper): Global exposure of seedlings to pathogen-derived signals induces pH and redox response gradients from roots and petioles to hypocotyls. (A) Five-day-old seedlings expressing the cytosolic pH or redox sensors, pUBQ10::pHGFP or p35S::roGFP2-Orp1, were used to monitor immune responses over 120 min in petioles, hypocotyls, and roots after treatment with 100 µM flg22 or elf18, or ddH2O (mock). (B) Representative microscopy images (of the merged channel) of seedlings treated with ddH2O (mock), elf18, or flg22 at the indicated time points reveal cytosolic acidification and oxidation [calibration bar using the Rainbow Look-Up Table (LUT) shows a shift from blue towards red]; scale bar=250 µm. (C) Quantification of relative acidification and oxidation as shown in (B).

How do plants prepare for an attack?🌱 A team led by Hans-Henning Kunz @kunzlab.bsky.social identified ion channels in chloroplasts that play a key role in connecting early stress signaling with the plant’s defense machinery. This can help them to respond faster & more strongly when stress returns.
