text: Size control is a fundamental question in biology, showing incremental complexity
in plants, whose cells possess a rigid cell wall. The phytohormone auxin is a
vital growth regulator with central importance for differential growth control.
Our results indicate that auxin-reliant growth programs affect the molecular complexity
of xyloglucans, the major type of cell wall hemicellulose in eudicots. Auxin-dependent
induction and repression of growth coincide with reduced and enhanced molecular
complexity of xyloglucans, respectively. In agreement with a proposed function
in growth control, genetic interference with xyloglucan side decorations distinctly
modulates auxin-dependent differential growth rates. Our work proposes that auxin-dependent
growth programs have a spatially defined effect on xyloglucan’s molecular structure,
which in turn affects cell wall mechanics and specifies differential, gravitropic
hypocotyl growth.
