Cytokinin Dehydrogenase in Xylem Sap Reveals A Direct Link Between Cytokinin Metabolism and Long-Distance Transport

This study identifies xylem-located cytokinin oxidase/dehydrogenase (CKX) activity in oats, showing its role in modulating root-to-shoot cytokinin translocation through metabolic degradation.

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.

Molecular basis of differential adventitious rooting competence in poplar genotypes

The paper identifies molecular differences in adventitious rooting competence between two poplar genotypes and shows that MYC2 expression levels influence rooting ability.

Red light controls adventitious root regeneration by modulating hormone homeostasis in Picea abies seedlings

This study shows red light promotes adventitious root initiation in Norway spruce seedlings by modulating hormone homeostasis, specifically reducing jasmonate and cytokinin levels.

A bacterial assay for rapid screening of IAA catabolic enzymes

This paper introduces a bacterial assay to rapidly screen IAA catabolic enzymes by measuring enzymatic products directly from bacterial cultures without protein purification.

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.
