Plant meristematic cells primarily exhibit:
Plant meristematic cells possess remarkable totipotency, capacity of single somatic cell to regenerate fully fertile organism under appropriate in vitro hormone combination auxin to cytokinin ratio. Unlike most animal somatic cells, differentiated plant cells retain genomic equivalence and can dedifferentiate, reactivating embryonic transcriptional regulators via auxin-induced expression of PLT, BABYBOOM, LEAFY COTYLEDON1/2, and WUS pathways resetting developmental potential. Underlying mechanism involves chromatin remodeling and reestablishment of shoot and root niches enabling callus formati
