Cell proliferation patterns at the shoot apical meristem
Current Opinion in Plant Biology, 2005The highly stereotypic cell proliferation patterns in many plant species suggest that the strict control of the cell cycle in time and space is an essential basis for ordered development. At the same time, conflicting evidence contradicts this view, indicating that cell division simply follows growth patterns that are dictated by the local availability

GENETICS OF ANGIOSPERM SHOOT APICAL MERISTEM DEVELOPMENT
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract Recent progress has been made in the genetic dissection of angiosperm shoot apical meristem (SAM) structure and function. Genes required for proper SAM development have been identified in a variety of species through the isolation of mutants.

Shoot Apical Meristem Form and Function
2010The shoot apical meristem (SAM) generates above-ground aerial organs throughout the lifespan of higher plants. In order to fulfill this function, the meristem must maintain a balance between the self-renewal of a reservoir of central stem cells and organ initiation from peripheral cells.

Stem cell maintenance in shoot apical meristems
Current Opinion in Plant Biology, 2012Stem cell homeostasis in shoot apical meristems of higher plants is regulated through a dynamic balance between spatial regulation of gene expression, cell growth patterns and patterns of differentiation. Cell-cell communication mediated by both the local factors and long-range signals have been implicated in stem cell homeostasis.

The effect of cadmium on shoot apical meristems of barley
Russian Journal of Developmental Biology, 2006We studied the effects of cadmium acetate at various concentrations (200 to 800 mg/kg substrate) on growth and development of shoot apical meristem of the barley plants (Hordeum vulgare L.) under the conditions of vegetative experiment. It was shown that in the presence of increasing cadmium concentrations in the soil substrate, the apex length and ...

Cellular basis of shoot apical meristem development
2001Shoot apical meristems are composed of proliferating, embryonic type cells, that generate tissues and organs throughout the life of the plant. This review covers the cell biology of the higher plant shoot apical meristem (SAM). The first section describes the molecular basis of plant cell growth and division.

Shoot and Root Apical Meristems
2017The structure and organization of the shoot and root apical meristems is presented. Their functional zones and mechanism of functioning are described. The shoot apical meristem is presented as a dynamic structure that changes during leaf and stem formation.

The role of hormones in shoot apical meristem function
Current Opinion in Plant Biology, 2006Plant organs are produced in meristems in a continuous and predictable but nevertheless flexible manner. Phytohormones and transcription factors cooperate to balance meristem maintenance and organ production. Recent research has provided clues to the mechanisms underlying this cooperation.

Bacterial Shoot Apical Meristem Inoculation Assay
2019By virtue of their sessile nature, plants may not show the fight-and-flight response, but they are not devoid of protecting themselves from disease-causing agents, attack by herbivores, and damages that are caused by other environmental factors. Plants differentially protect their life-sustaining organs such as plant apexes from the attack by microbial

Cell Differentiation and Organ Initiation at the Shoot Apical Meristem
Plant Molecular Biology, 2006Plants continuously generate organs at the flanks of their shoot apical meristems (SAMs). The patterns in which these organs are initiated, also called patterns of phyllotaxis, are highly stereotypic and characteristic for a particular species or developmental stage.
