The TOR–EIN2 axis mediates nuclear signalling to modulate plant growth
In Arabidopsis, phosphorylation of EIN2 by TOR kinase in the presence of glucose prevents the nuclear localization of EIN2, showing that the glucose–TOR–EIN2 axis regulates the transcriptome independently of ethylene signalling pathways.

RGF1 controls root meristem size through ROS signalling
RITF1, a newly identified plant transcription factor, links signalling through the peptide hormone RGF1 to the balance of reactive oxygen species and thereby enhances the stability of another transcription factor, PLETHORA2, a master regulator of root stem cells.

Mobile PEAR transcription factors integrate positional cues to prime cambial growth
Radial growth in the roots of Arabidopsis, which is mediated by gene expression activated by the mobile PEAR1 and PEAR2 transcription factors, is initiated around protophloem-sieve-element cell files of procambial tissue.

A molecular rheostat adjusts auxin flux to promote root protophloem differentiation
The coordinated action of BREVIS RADIX (BRX) and PROTEIN KINASE ASSOCIATED WITH BRX (PAX) regulates auxin flux during the development of protophloem sieve elements in the root meristem of Arabidopsis.

PLETHORA gradient formation mechanism separates auxin responses
Through a combination of experimental and computational approaches, the interplay between the plant hormone auxin and the auxin-induced PLETHORA transcription factors is shown to control zonation and gravity-prompted growth movements in plants.
