The paper identifies three homeodomain zinc-finger transcription factors that repress cambium activity in Arabidopsis by inhibiting auxin, cytokinin, and TDIF-PXY target genes.

This study identifies PXY-ER complexes as essential for cambium activity in Arabidopsis, showing that PXY signaling depends on ER signaling and explains ER function in the cambium.

The paper identifies a network of transcriptional repressors that regulate ARF activator gene expression in Arabidopsis thaliana, contributing to auxin response specificity.
