Regulation of Shoot Apical Meristem and Axillary Meristem Development in Plants [PDF]
International Journal of Molecular Sciences, 2020 Plants retain the ability to produce new organs throughout their life cycles. Continuous aboveground organogenesis is achieved by meristems, which are mainly organized, established, and maintained in the shoot apex and leaf axils. This paper will focus on reviewing the recent progress in understanding the regulation of shoot apical meristem and ...

Journal of Plant Research, 2008
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

Cell signaling in the shoot apical meristem
Plant Physiology, 2023AbstractDistinct from animals, plants maintain organogenesis from specialized tissues termed meristems throughout life. In the shoot apex, the shoot apical meristem (SAM) produces all aerial organs, such as leaves, from its periphery. For this, the SAM needs to precisely balance stem cell renewal and differentiation, which is achieved through dynamic ...

Flowering and apical meristem growth dynamics [PDF]
Journal of Experimental Botany, 2008 The shoot apical meristem generates stem, leaves, and lateral shoot meristems during the entire shoot ontogeny. Vegetative leaves are generated by the meristem in the vegetative developmental phase, while in the reproductive phase either bracts subtending lateral flower primordia (or paraclades), or perianth and strictly reproductive organs are formed.

Formation and maintenance of the shoot apical meristem
Trends in Plant Science, 2000Development in higher plants is characterized by the reiterative formation of lateral organs from the flanks of shoot apical meristems. Because organs are produced continuously throughout the life cycle, the shoot apical meristem must maintain a pluripotent stem cell population. These two tasks are accomplished within separate functional domains of the

Models of shoot apical meristem function [PDF]
New Phytologist, 2003 SummaryIn this review we describe how concepts of shoot apical meristem function have developed over time. The role of the scientist is emphasized, as proposer, receiver and evaluator of ideas about the shoot apical meristem. Models have become increasingly popular over the last 250 years, and we consider their role. They provide valuable grounding for

MicroRNAs in the shoot apical meristem of soybean
Journal of Experimental Botany, 2011Plant microRNAs (miRNAs) play crucial regulatory roles in various developmental processes. In this study, we characterize the miRNA profile of the shoot apical meristem (SAM) of an important legume crop, soybean, by integrating high-throughput sequencing data with miRNA microarray analysis.

Apical meristems: the plant's fountain of youth
BioEssays, 2003AbstractDuring postembryonic development, all organs of a plant are ultimately derived from a few pluripotent stem cells found in specialized structures called apical meristems. Here we discuss our current knowledge about the regulation of plant stem cells and their environments with main emphasis on the shoot apical meristem of Arabidopsis thaliana ...

Apical cells are universally present in lower plants and their description has been mostly viewed morphologically as single-celled meristems. This study attempts to demonstrate that the roles of apical cells and more generally of meristems collectively are (a) often the proliferative source of all cells in a plant, (b) sometimes a formative centre in ...

Analyzing Shoot Apical Meristem Development
2010The shoot apical meristem of Arabidopsis thaliana contains a reservoir of pluripotent stem cells that functions as a continuous source of new cells for organ formation during development. The SAM forms during embryogenesis, when it becomes stratified into specific cell layers and zones that can be delineated based on morphological and molecular ...
