Function of the pericycle
WebThey originate by cell division of pericycle cells opposite a protoxylem group. The root starts to swell as the new lateral root penetrates outwards towards the surface, pushing its way through cortical parenchyma cells and finally bursting out through the epidermis into the soil. WebTherefore, a model has been proposed where: (1) KRP2 inhibits progression of xylem-pole pericycle cells through the cell cycle; (2) down-regulation of KRP2 in specific cells within a certain developmental window allows those cells to continue through the cell cycle and (3) other cells retain high KRP2 expression and are not competent to progress …
