While the shoot apical meristem (SAM) formed in the embryo only contributes to the main stem, the branched structure observed in many plants relies on axillary meristems (AMs) formed post-embryonically. (researchgate.net)
A larger vegetative shoot apical meristem (SAM) often produces more branching inflorescences. (nature.com)
Day length is measured in leaves and, when appropriate, leads to the production of floral stimuli called florigens that are transmitted to the shoot apical meristem to initiate inflorescence development1. (bvsalud.org)
Here we show that the arrival of Hd3a and RFT1 at the shoot apical meristem activates FLOWERING LOCUS T-LIKE 1 (FT-L1), encoding a florigen-like protein that shows features partially differentiating it from typical florigens. (bvsalud.org)
The subsequent studies considered that higher plants share two essential features of floral transition: Generation of floral stimulus in leaves and its transport to the target, shoot apical meristem (SAM), which must be competent to receive it [ 2 ]. (jabonline.in)
Marco Incarbone, previously a postdoctoral researcher in the group of Ortrun Mittelsten Scheid at the Gregor Mendel Institute of the Austrian Academy of Sciences (GMI) and now a group leader at the Max Planck Institute of Molecular Plant Physiology in Germany sought to uncover the molecular bases of how stem cells in the shoot apical meristem fight off viruses together with PhD student Gabriele Bradamante and other GMI group members.

Plant Tissue culture is the in vitro aseptic culture of cells, tissues, organs, or whole plant under controlled nutritional and environmental conditions often to produce the clones of plants. (vasportsnutrition.com)
This small group of cells generates all plant tissues above ground, including the next plant generation, and for reasons still poorly understood, viruses are unable to proliferate in these cells. (oeaw.ac.at)
So the growth of a tree depends on the meristems which create tissues and organs that enlarge the above-ground and below-ground biomass (primary growth) and widen the tree (secondary growth). (bonsai-science.com)
The post-embryonic development of above-ground tissues in plants is dependent upon the maintenance and differentiation of stem cells at the shoot meristem. (biologists.com)
A functional shoot meristem is maintained through a tightly controlled balance between the proliferation of a group of stem cells residing in the center, and the differentiation of their peripheral and basal progeny cells for the formation of organ primordia and other differentiated tissues. (biologists.com)
Shoot5
The formation of new meristems is essential for the plastic expansion of the highly branched shoot and root systems. (researchgate.net)
A particular organ (Reproductive or somatic) like root or shoot meristems or leaf primordia or floral buds is isolated and cultured. (cbsetuts.com)
Our findings suggest that POL and PLL1 are central players in regulating the balance between stem-cell maintenance and differentiation, and are the closest known factors to WUS regulation in the shoot meristem. (biologists.com)
The adult plant body is generated from the continuous and re-iterative organogenesis at two stem-cell containing structures: the shoot and root meristems. (biologists.com)
Vegetative1
The jointless ( j ) mutant produces indeterminate inflorescences that revert to vegetative growth after the production of two or three flowers 16 , 17 . (nature.com)
Tightly controlled1
These organs themselves go through developmental stages, so it is also believed for example that "leaves maintain their own meristems, and that the tightly controlled activity of these meristems directs the complex process of leaf tissue development. (bonsai-science.com)
Embryo2
However, once an embryo is formed from a seed, plants have an important difference from animals because they possess 'plastic development' ref - which means that they can change the types of cells they produce at any given time. (bonsai-science.com)
Besides the zygotic embryo is produced like lemons and oranges. (cbsetuts.com)
Recent findings have shown that transient inactivation of the CLV pathway leads to rapid alterations in the expression of meristem regulators, consistent with earlier studies investigating the effect of clv mutations on WUS expression( Reddy and Meyerowitz, 2005 ). (biologists.com)

Both the SAM and the RAM generate more stem cells as well as the plant organs, to enable continued growth. (bonsai-science.com)
In the fight against Turnip mosaic virus, both salicylic acid and RDR1 are necessary to expel the virus from the stem cells - however, RDR1 is not produced within the stem cells themselves, but in the tissue below the stem cells and in the vasculature, Incarbone adds. (oeaw.ac.at)
