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.

PHOSPHATASE ACTIVITY AND CELLULAR DIFFERENTIATION IN PHLEUM ROOT MERISTEM
American Journal of Botany, 1964Using 9 different organic phosphate substrates as alternatives in a standardized 5′‐nucleotidase histochemical test system, enzyme activity patterns were recorded for timothy grass root epidermis. At least 4 different phosphatases were distinguished on the bases of substrate specificity, reaction rate, tissue distribution, and response to inhibitors ...

Summary Plants can record external stimuli in mobile mRNAs and systemically deliver them to distal tissues to adjust development. Despite the identification of thousands of mobile mRNAs, the functional relevance of mobile mRNAs remains limited. Many mobile mRNAs are synthesized in the source cells that perceive environmental stimuli, but specifically ...

Influence of cell size on differentiation of root meristem cells
Environmental and Experimental Botany, 1987Abstract Cell size and meristem length were analyzed in steady-state growing roots in the presence of low concentrations of hydroxyurea. The ability of cells to undergo differentiation was related to cell size so that the larger the proliferating cell size, the shorter the meristem length. Results suggest the existence of a cell size requirement that,

Temperature effects on meristem differentiation and flowering date in tuberose (Agave amica L.)
Scientia Horticulturae, 2021Abstract Tuberose is an ornamental plant of economic importance produced worldwide due to the elegant shape and fragrant flowers. Despite its commercial importance, one of the limitations of tuberose production is control of flowering time, which has not been determined at present.

Cell Differentiation in Shoot Meristem: A Molecular Perspective
2006The basic body plan of higher plants is laid down during embryogenesis, however, the entire adult plant develops post-embryonically through the activity of two meristems (shoot and root apical meristems) established originally at the opposite ends of the embryo. This article focuses on the shoot apical meristem (SAM), which is primarily responsible for

Magnetic field affects meristem activity and cell differentiation inZea maysroots
Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2006Abstract Exposure of Zea mays seedlings to a continuous electromagnetic field (EMF) for 30 h induced a 30% stimulation in the rate of root elongation compared with the controls. It also resulted in a significant increase of cell expansion, in both the acropetal (metaxylem cell lineage) and basipetal (root cap cells) direction.

In dicot plants, the process by which undifferentiated plastids, termed proplastids, differentiate into mature functional chloroplasts begins in the shoot apical meristem (SAM) and young leaf primordia, and continues along leaf development. In this work, we followed initial chloroplast biogenesis in cells of the SAM in Arabidopsis, during the early ...

DEVELOPMENTAL POTENCY, DIFFERENTIATION AND PATTERN IN MERISTEMS OF MONSTERA DELICIOSA
American Journal of Botany, 1944INDUCTION OF regeneration processes is an important tool in the analysis of histological differentiation. Not only have terminal meristems generally the capability of more or less direct reproduction of cells in injured regions, but it is frequently possible to induce by means of the wounding technique redifferentiation of specific and varied tissue ...
