meristem

or

meristematic tissue

a region of a plant in which active cell division (MITOSIS) occurs, the cells of the meristem not being differentiated into a specialist form. Meristematic tissues occur at the root and shoot tips (see APICAL MERISTEM giving growth in length, while increase in girth of the plant is produced by the CAMBIUM of VASCULAR BUNDLES and the INTERFASCICULAR CAMBIUM. Note that such specialist dividing zones are not found in animals, where cell division occurs in most tissues.

In the apical meristem, ablation of the selected cells can increase the persistence of meri-clone regeneration, which results in the production of virus-free plantlets at high propotion (Nascimento et al., 2003; Wasswa et al., 2010; Wang and Valkonen, 2008).

The use of direct regeneration systems via organized meristem cultures such as enhanced axillary branches are preferred (Vasil, 1994), because they can resist genetic changes occurring during cell division and differentiation and produce true to type plants (Shenoy and Vasil, 1992).
