Abstract

Plants can show flexible capacity of coping with the impairing factors of their abiotic and biotic environment and their high developmental plasticity, and easily forced cellular totipotency is a general feature. Plants have a notable potential to maintain separate cell groups in their apical meristems to assure growing. In addition to these proembryonic cell division centers, plants posses various manners (e.g., dormant meristemoids and residual stem cells) to acquire cell division capability in their bodies and, as a result, the daughter cells achieve an altered differentiation status there. The initiated growth and regeneration might also be based on newly formed dividing cells entering again into the cell cycle, and the different cell fate of unequal daughter cells is usually fundamental in the realization of altered development. In the latter case, a precondition of the subsequent events is dedifferentiation of mature, specialized cells and remodeling of their genetic program. Our results demonstrate that cells may attain disparate dedifferentiation statuses depending on their ancestry, and the initiated redifferentiation processes might be arrested even before entering cell divisions or continued up to complete root formation. Transfer cells of leaf veins share function in short-distance transport under normal conditions and stem cell formation under forced organogenesis. The Rubia tinctorum in vitro model system allowed us to detect the main symptoms of the rapid morphological changes during dedifferentiation. Modification of cell wall structure, enhanced autophagic activity, asymmetric plastid fission and unequal cell division seem to be basic steps of meristemoid (stem cell) formation. The theoretical background and the importance of the cytological characteristics mentioned above are also discussed.
