No experimental confirmation available;TISSUE SPECIFICITY:Specifically expressed in root cap cells.INDUCTION:Down-regulated by auxin (IAA) and abscisic acid (ABA).MISCELLANEOUS:The sloughing of root-cap cells from the root tip is a process of cell-cell separation that entails cell wall break down. It is important in plant development because it assists the growing root in penetrating the soil.SIMILARITY:Belongs to the glycosyl hydrolase 9 (cellulase E) family."
