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.

Expanding KitBase: Genome and Phenotype Integration of 3,268 Fast-Neutron Rice Mutants

The paper expands KitBase with genomic and phenotypic data from 3,268 fast-neutron rice mutants, identifying mutations and linking them to agronomic traits.

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.
