The MAP kinase scaffold MORG1 shapes cell death in unresolved ER stress in Arabidopsis
Joo Yong Kim, Dae Kwan Ko, Federica Brandizzí
The paper identifies MORG1 as a regulator of ER stress tolerance in Arabidopsis by modulating MPK6-dependent phosphorylation of WRKY8, revealing a signaling axis that fine-tunes UPR gene expression.
