Salicylic acid engages central metabolic regulators SnRK1 and TOR to govern immunity by differential phosphorylation of NPR1
The immune signal SA triggers metabolic changes to activate SnRK1 while inhibiting TOR. These central metabolic kinases antagonistically phosphorylate the key immune regulator NPR1, thereby coupling cellular metabolic state to systemic acquired resistance.

In a nutshell🥜: - Plant proteasome gene repertoire expansion drove subunit evolution - Proteasome homeostasis maintenance mechanism is a multi-layered process which has diversified in plants - This diversification is influenced by a GRN embedding proteasome within the proteostasis network

The ARLA1A-NAC089 module coordinates ER phagy with the unfolded protein response to maintain cellular homeostasis in plants
Yang et al. reveal that the ARLA1A-NAC089 module couples ER phagy with the UPR in plants. This dual regulatory axis fine-tunes cell survival versus death under stress, providing a mechanistic framework for maintaining ER homeostasis and enhancing environmental resilience.
