developmental processes during which cell wall modification occurs. Cell wall remodeling
proteins including expansins have been suggested to be involved in cell separation to
facilitate the emergence of lateral roots (LRs) through the overlaying tissues of the primary
root. LBD18/ASL20 activates EXPANSINA14 (EXPA14) expression by directly binding to the
EXPA14 promoter to enhance LR emergence in Arabidopsis thaliana. Here we show that …
