Background technology
As higher organism, the difference of the maximum of Plants and Animals be plant must set growth, the fixing and nutritive substance of this growth draw the growth that must depend on root system of plant consumingly.So the good growth of growing for plant integral body of root system plays crucial effects.No matter be monocotyledons or dicotyledons, though the structure of root system and form are different, all to form for sophisticated by root cap district, meristematic zone, elongation zone and maturation zone four parts, wherein every part is all being carried out different functions.Root cap is made up of central root cap cell and side root cap cell, and along with the continuous growth of the tip of a root, thereby root cap cell detachment has foremost played the effect of protection to the tip of a root; Central root cap cell contains a large amount of starch small graiies simultaneously, plays the effect of experiencing gravity, thereby makes the root of plant produce geotropic growth.Meristematic zone is made up of the cell that is in division stage, and the continuous division of these cells just makes the number of cell increase, and root is constantly grown.The elongation zone is made up of the cell between splitting status and differentiation state, is the transitory stage between the two.The maturation zone is made up of well differentiated cell, and the cell size and form of these differentiation and maturations no longer changes, and carries out different functions separately.
The stem cell that is called as initiating cell in the Arabidopis thaliana root meristematic tissue has produced various types of cells in every confluent monolayer cells layer by the spatial division, and these cells have been formed a vegetative clone.One in two daughter cells that initiating cell produces through division is once still keeping primitiveness, and the another one cell becomes transit-amplifyingcell (TA cell), this cell through division many times after, be differentiated to form self characteristics.The cell that is centered around the quiescent center (QC) of initiating cell central authorities seldom divides and stem cell has on every side been formed the merismatic stem cell of root habitat (stem cell niche), and QC is the organization center of this niche.QC by and the signal communication of stem cell on every side, suppress its differentiation, the primitiveness that keeps stem cell, at present very few for the understanding of these signaling molecule essence, but from root meristematic tissue and the merismatic contrast of bud, find, the initiating cell of root is similar to the merismatic stem cell of bud, and QC is similar to the OC cell of expressing WUS.
