A nutrient-responsive chromatin complex balances growth and stress tolerance

We identified the nutrient-responsive chromatin-associated complex for growth (CACG), which is critical for plant growth. Under nutrient-rich conditions, active TOR kinase promotes the translation of CACG components. CACG binds stress-responsive genes marked by histone acetylation, suppressing their growth-limiting transcription. During nutrient deficiency, inactive TOR reduces the translation of CACG components, alleviating transcriptional repression to prioritize stress tolerance over growth.
