the apoplast is of essential significance in cell communication and identification; the apoplast signal molecules, too, plays an important role in the growth and development of plant cells.
质外体在细胞间的通讯及识别上有重要意义,质外体信号分子对植物细胞的生长发育也起着非常重要的作用。
symplast pathway and transcelluar pathway is difficultly distinguished by experiment methods, and have no valid ways to make distinction between apoplast and cell to cell pathway.
further studies showed that exogenous aba treatment and water stress could enhance the activities of plasma membrane (pm) nadph oxidase, cell wall pod, apoplast pao significantly.
