The plant Hippo signalling network has evolved into a central hub that integrates hormonal, developmental and stress inputs to govern growth–defence–reproduction trade-offs.
- Why it matters: Sessile plants must dynamically allocate limited resources, but how a conserved signalling system becomes a context-sensitive decision-maker for these trade-offs is unclear.
- What they did: The authors propose an “adaptive trade-off management” framework, highlighting plant-specific innovations including a direct SIK1–MOB1 interaction bypassing SAV1, dual-specificity NDR kinases, and MOB1A/B heterodimers.
- The result: Antagonism between SIK1 and MOB1 fine-tunes the jasmonate pathway as a molecular rheostat for growth–defence balance, enabling a research agenda to quantify hub signal flux and engineer crops for optimized resilience and yield.
