Annual Review of Plant Biology, 2019
A fascinating feature of plant growth and development is that plants initiate organs continually throughout their lifespan. The ability to do this relies on specialized groups of pluripotent stem cells termed meristems, which allow for the elaboration of the shoot, root, and vascular systems.

Turning Meristems into Fortresses
Trends in Plant Science, 2019TERMINAL FLOWER1 (TFL1) was named from knockout Arabidopsis thaliana mutants in which the inflorescence abnormally terminates into a flower. In wild type plants, the expression of TFL1 in the center of the inflorescence meristem represses the flower meristem identity genes LEAFY (LFY) and APETALA1 (AP1) to maintain indeterminacy.

Patterning the floral meristem
Seminars in Cell & Developmental Biology, 1998Flowers are reproductive structures unique to the angiosperms. Flowers, which develop from small mounds of cells called floral meristems, show a number of universal patterns such as the arrangement of organs of different type along the floral axis.

The plant meristems, shoot apical meristem (SAM) and root apical meristem (RAM), are unique structures made up of a self-renewing population of undifferentiated pluripotent stem cells. The SAM produces all aerial parts of postembryonic organs, and the RAM promotes the continuous growth of roots. Even though the structures of the SAM and RAM differ, the

The essence of meristem-tip culture is the excision of the organized apex of the shoot from a selected donor plant for subsequent in vitro culture. The conditions of culture are regulated to allow only for organized outgrowth of the apex directly into a shoot, without the intervention of any adventitious organs (1-3).

Cell division is a fundamental requirement for growth and development of the plant body. Aside from certain stages of sexual reproduction, all production of new cells is based on a process called the cell cycle in which nuclear division (mitosis) and cell division (cytokinesis) produce two identical daughter cells.

How Floral Meristems are Built
Plant Molecular Biology, 2006The formation of flowers involves the activity of a genetic network that acts in meristems to specify floral identity. The main output of this network is the initiation of a developmental patterning program for the generation of floral organs. The first characteristic of meristem identity genes is their capacity to integrate the environmental and ...

In this chapter, the structure, function, and growth of apical meristems and cambium are discussed from a perspective of mechanics. We first characterize the meristems and point to implications of the symplasm, apoplasm, and organismal concepts for our understanding of plant morphogenesis.

GENETICS Plant development is regulated by meristems, which give rise to all plant organs, including the root, shoot, and flowers. In Arabidopsis , the meristem is controlled primarily by a signaling cascade initiated by CLAVATA (CLA) receptors that are activated by CLE peptides. Suzaki et al. have examined homologs of the Arabidopsis CLAVATA3 protein (
