Conjugation of cis-OPDA with amino acids is a conserved pathway affecting cis-OPDA homeostasis upon stress responses

This study identifies OPDA-amino acid conjugates as a conserved mechanism for regulating cis-OPDA homeostasis in plants during stress responses.

IPT9, a cis-zeatin cytokinin biosynthesis gene, promotes root growth

The paper investigates the role of IPT9 in cytokinin biosynthesis and its impact on root growth, finding that IPT9 affects auxin homeostasis and contributes to a short-root phenotype despite reduced cis-zeatin levels.

DNA damage inhibits root growth by enhancing cytokinin biosynthesis in Arabidopsis thaliana.

This study shows DNA damage in Arabidopsis roots increases cytokinin synthesis, which suppresses auxin transport and reduces root growth.

Conifers exhibit a characteristic inactivation of auxin to maintain tissue homeostasis

The paper investigates IAA inactivation pathways in conifers, finding that oxidative and conjugative pathways differ in their contribution to auxin homeostasis compared to Arabidopsis.

Cell-surface receptors enable perception of extracellular cytokinins

The paper shows that cytokinin perception occurs via plasma membrane receptors in root cells, challenging previous assumptions about receptor localization and highlighting the role of spatial distribution in signaling.

A role for the auxin precursor anthranilic acid in root gravitropism via regulation of PIN-FORMED protein polarity and relocalization in Arabidopsis

This study shows that anthranilic acid regulates PIN-FORMED protein polarity and relocalization in Arabidopsis roots, affecting gravitropism independently of its role in IAA biosynthesis.
