Signaling by a tyrosine-sulfated peptide balances growth and osmotic stress response in rice

Overexpressing rice peptide OsPSY8 lengthens roots but lowers osmotic stress survival, while knockout raises it; OsWRKY24 represses the OsPSY8 promoter and is induced by PEG.

The Sulfated PSY Peptide Negatively Regulates Receptor Kinase Activity to Promote Growth

In Physcomitrium patens, genetic evidence suggests sulfated PSY peptide binding inactivates its receptor kinases rather than activating them; kinase-dead receptors rescue tpst mutants, while receptor overexpression phenocopies loss of sulfation.

Evidence for Early Evolution of Sulfated Peptide Signaling in Plant Development

The paper shows that sulfotyrosyl peptide signaling via TPST is essential for plant development in Physcomitrium patens, with conserved function across species.

Reduced methane emissions in transgenic rice genotypes are associated with altered rhizosphere microbial hydrogen cycling

This study shows that transgenic rice genotypes overexpressing PSY genes reduce methane emissions by altering rhizosphere microbial hydrogen cycling through changes in gene activity and metabolic pathways.

Transcription factor-promoter interactions for PSY/PSYR-mediated regulation of root growth

The paper maps transcription factor-promoter interactions for PSY/PSYR genes in Arabidopsis, identifies key regulators of root growth, and validates a CRF10-binding motif's role in growth regulation.

Combining Directed Evolution with Machine Learning Enables Accurate Genotype-to-Phenotype Predictions

The paper combines directed evolution with a protein language model to predict genotype-to-phenotype relationships in rice immune receptors, identifying variants with improved ligand binding.

Directed evolution of a plant immune receptor for broad spectrum recognition of pathogen effectors

This study uses directed evolution to engineer a plant immune receptor to recognize diverse pathogen effectors, enhancing broad-spectrum resistance in crops.

Tyrosine-sulfated peptide hormone induces flavonol biosynthesis to control elongation and differentiation in Arabidopsis primary root.

This study shows that the peptide hormone PSY1 promotes root growth by inducing flavonol biosynthesis, which regulates cell elongation and differentiation in Arabidopsis.

A pan-plant protein complex map reveals deep conservation and novel assemblies

The paper maps protein complexes across 13 plant species, revealing conserved and novel assemblies with agricultural relevance.

Genome sequence of the model rice variety KitaakeX

The paper reports the de novo genome sequencing and analysis of the rice variety KitaakeX, identifying genomic variations and providing a high-quality reference for rice functional genomics.

A histidine kinase gene is required for large radius root tip circumnutation and surface exploration in rice

This study identifies a histidine kinase gene, OsHK1, essential for root tip circumnutation and surface exploration in rice, with cytokinin signaling involvement.
