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.

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

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

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.
