The quiescent center is the mitotically inactive portion of the root tip that acts as a reserve of healthy cells in case the apical meristem becomes damaged.
Quiescent center cells exhibit high resistance to ionizing radiation, especially when compared to surrounding initial cells, leading to the hypothesis that the quiescent center functions as a stem cell reservoir, ensuring the rejuvenation and perseverance of the root apical meristem.
The root quiescent center is a pool of rarely dividing stem cells inside the root apical meristem. The Quiescent center maintains the environment more regularly by dividing initials, forming the root apical meristem cell niche.
