Tao et al. show that SCRN1 acts as a scaffold to facilitate GPX4 phosphorylation by STK38, thereby preventing chaperone-mediated autophagy of GPX4 and subsequent ferroptosis in patient-derived organoids and mouse models for hepatocellular carcinoma.

USP17L, encoded by a gene family expressed in mouse 2-cell embryos and 2-cell-like cells, is shown to promote the 2-cell program in mESCs at both transcriptional and post-translational levels, in part through deubiquitinating H2AK119ub1 and ZSCAN4.

The powdery mildew resistance of the MLIW170/PM26 locus, which originated from wild emmer wheat, is determined by a genetically linked atypical NLR gene pair, TdCNL1 and TdCNL5, with TdCNL1 encoding an atypical nucleotide-binding leucine-rich repeat protein integrating a potassium-dependent sodium-calcium exchanger domain.
