Dear Editor,Plant tissues derived from meristems including SAM (shoot apical meristem) and RAM (root apical meristem) are located at the tips of shoot and root and procambial cell tissues in the vascular system (Simon and Stahl,2011).Through asymmetric periclinal cell division,a few layers of stem cells in vascular meristems differentiate into apposing xylem and phloem cells,forming the conducting system and playing an important role in long-distance transport of water,nutrients,sugars,and signaling molecules such as hormones in plant (Elo et al.,2013).
