Genetic dissection of cell wall defects and the strigolactone pathway in Arabidopsis
Defects in the biosynthesis and/or deposition of secondary plant cell wall polymers result in the collapse of xylem vessels causing a dwarfed plant stature and an altered plant architecture termed irregular xylem (irx) syndrome. For example, reduced xylan O‐acetylation causes strong developmental de...
