BatR: A novel regulator of antibiotic tolerance in Pseudomonas aeruginosa biofilms

This study identifies PA3049, renamed BatR, as a key regulator of antibiotic tolerance in Pseudomonas aeruginosa biofilms, showing its role in stress response and antimicrobial resistance.

Initiation of B-type starch granules in wheat endosperm requires the plastidial α-glucan phosphorylase PHS1

This study identifies PHS1's role in initiating B-type starch granules in wheat endosperm, showing it interacts with BGC1 and is exclusive to B-type granule formation.

Post-translational modification of SPATULA by SECRET AGENT and SPINDLY promotes organ symmetry transition at the gynoecium apex

The paper shows that SPINDLY and SECRET AGENT modify SPATULA with O-fucose and O-GlcNAc to promote a symmetry transition in the gynoecium.

Plasmid manipulation of bacterial behaviour through translational regulatory crosstalk

This paper identifies RsmQ as a plasmid translational regulator that globally controls bacterial behavior by altering the proteome, leading to a switch from motile to sessile lifestyle.

A histone variant condenses flowering plant sperm via chromatin phase separation

This study identifies H2B.8 as a histone variant that mediates chromatin condensation in flowering plant sperm through phase separation, enabling nuclear compaction without transcriptional inhibition.

Metabolic constraints on nitrogen fixation by rhizobia in legume nodules

The paper models bacteroid metabolism in legume nodules to show how oxygen levels and dicarboxylate catabolism affect nitrogen fixation and redox balance.

Second messenger control of mRNA translation by dynamic ribosome modification

This study shows that RimK modifies ribosomal protein RpsF in Pseudomonas fluorescens to regulate translation, with activity controlled by RimA, RimB, and cyclic-di-GMP.

The Receptor Kinase BRI1 promotes cell proliferation in Arabidopsis by phosphorylation- mediated inhibition of the growth repressing peptidase DA1.

The paper shows BRI1 phosphorylates DA1 to inhibit its growth-repressing activity, maintaining cell proliferation during leaf growth in Arabidopsis.

First evidence of production of the lantibiotic nisin P

The paper identifies a human fecal isolate producing nisin P, confirms its structure, and compares its antimicrobial activity to nisin A and H.

Uncoupled activation and cyclisation in catmint reductive terpenoid biosynthesis

The paper identifies NEPS enzymes in catmint that catalyse stereoselective cyclisation of an enol intermediate into nepetalactol isomers, revealing uncoupled activation and cyclisation in reductive terpenoid biosynthesis.

Ubiquitylation activates a peptidase that promotes cleavage and destabilization of its activating E3 ligases and diverse growth regulatory proteins to limit cell proliferation in Arabidopsis

The paper identifies DA1 as a ubiquitin-activated peptidase in Arabidopsis that cleaves and destabilizes E3 ligases and growth regulatory proteins to limit cell proliferation during organ development.
