Our finding reveals a general association of CLE peptide signaling with meristem homeostasis, a feature that evolved in the ancestral land plant, in both haploid and diploid phases. Apical meristems are the completely undifferentiated (indeterminate) meristems in a plant. These differentiate into three kinds of primary meristems. The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are involved in lateral growth.
