The paper uses CRISPR/Cas9 to create a septuple ARF mutant in Physcomitrium patens, showing reduced auxin-mediated gene induction but maintained basal expression, leading to less severe developmental defects than constitutive repression lines.

The paper identifies a conserved mechanism regulating class-B ARF protein levels in land plants through comparative mutant analysis in maize and moss.

The paper shows auxin signaling coordinates cell shape in Arabidopsis through global and local pathways involving TIR1/AFB and TMK.
