Commercial scale genetic transformation of mature seed embryo explants in maize
Frontiers in Plant Science, 2022 A novel, efficient maize genetic transformation system was developed using Agrobacterium-mediated transformation of embryo explants from mature seeds. Seeds from field grown plants were sterilized and crushed to isolate embryo explants consisting of the ...

Morphogenesis at the shoot meristem
Comptes Rendus. Biologies, 2023 Shoot apical meristems are populations of stem cells which initiate the aerial parts of higher plants. Work during the last decades has revealed a complex network of molecular regulators, which control both meristem maintenance and the production of different types of organs.

Auxin at the Shoot Apical Meristem [PDF]
Cold Spring Harbor Perspectives in Biology, 2010 Plants continuously generate new tissues and organs through the activity of populations of undifferentiated stem cells, called meristems. Here, we discuss the so-called shoot apical meristem (SAM), which generates all the aerial parts of the plant. It has been known for many years that auxin plays a central role in the functioning of this meristem ...

Transformation of Inhibitor of Meristem Activity (IMA) Gene into Jatropha curcas L.
Makara Journal of Science, 2015 Jatropha is one of the many biodiesel plants developed in tropical countries. Efforts to increase its productivity can be done using various methods of breeding. One of the breeding methods is the introduction of genes into the Jatropha plant. The aim of

Shaping the meristem by mechanical forces [PDF]
F1000 Biology Reports, 2009 A recent report shows that cells in the Arabidopsis apical meristem orientate their cortical microtubules along mechanical stress patterns generated during tissue morphogenesis. This in turn is expected to influence the mechanical properties of the cell via the modification of the cortical microtubule network and the cell wall.

AXR1 acts after lateral bud formation to inhibit lateral bud growth in Arabidopsis [PDF]
, 1999 The AXR1 gene of Arabidopsis is required for many auxin responses. The highly branched shoot phenotype of mature axr1 mutant plants has been taken as genetic evidence for a role of auxin in the control of shoot branching.

Nutrient Sensing in Plant Meristems [PDF]
Plant Molecular Biology, 2006 Plants need nutrient to grow and plant cells need nutrient to divide. The meristems are the factories and cells that are left behind will expand and differentiate. However, meristems are not simple homogenous entities; cells in different parts of the meristem do different things. Positional cues operate that can fate cells into different tissue domains.

The COP9 SIGNALOSOME is required for postembryonic meristem maintenance in Arabidopsis thaliana [PDF]
, 2015 Cullin-RING E3 ligases (CRLs) regulate different aspects of plant development, and are activated by modification of their cullin subunit with the ubiquitin-like protein NEDD8 (NEural precursor cell expressed Developmentally Down-regulated 8) (neddylation)

Active suppression of a leaf meristem orchestrates determinate leaf growth
eLife, 2016 Leaves are flat determinate organs derived from indeterminate shoot apical meristems. The presence of a specific leaf meristem is debated, as anatomical features typical of meristems are not present in leaves.

Frontiers in Plant Science, 2022 Somatic cells of higher plants possess the remarkable ability to regenerate new individuals via reestablishing apical meristems. Reconstitution of shoot meristem is the vital process and is required for application of plant biotechnology.
