Unlocking Nature’s Thermometer: Insights into Plant Temperature Signaling

To identify regulators of thermomorphogenesis that are conserved in flowering plants, researchers at PSB mapped changes in protein phosphorylation in both dicots and monocots exposed to warm temperature. They identified MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE KINASE4 (MAP4K4)/TARGET OF TEMPERATURE3 (TOT3) as a regulator of thermomorphogenesis in Arabidopsis and wheat. This approach can contribute to ensuring food security under a changing climate.
