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

María Florencia Ercoli, Alexandra M. Shigenaga, Artur Teixeira de Araújo…·Pamela C. Ronald

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

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

Ling-Dong Shi, María Florencia Ercoli, Junhyeong Kim…·Jillian F. Banfield

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.
