Somatic embryogenesis of selected coniferous tree species of the genera Picea, Abies and Larix

Acta Societatis Botanicorum Poloniae, 2011
Experiments on somatic embryogenesis in selected spruce, fir and larch species were performed to determine if this method of micropropagation enables production of quality seedlings for forest nurseries.

PRC2 Represses Hormone-Induced Somatic Embryogenesis in Vegetative Tissue of Arabidopsis thaliana

PLoS Genetics, 2017
Many plant cells can be reprogrammed into a pluripotent state that allows ectopic organ development. Inducing totipotent states to stimulate somatic embryo (SE) development is, however, challenging due to insufficient understanding of molecular barriers ...

Characterisation of the cacao somatic embryogenesis receptor-like kinase (SERK) gene expressed during somatic embryogenesis [PDF]

, 2005
Somatic embryogenesis is a useful tool for plant propagation and consists of a good model for embryo development studies. During somatic embryogenesis, some morphological and biochemical changes occur in response to alterations in gene expression ...

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Combined Karyotyping, Copy Number Variation Sequencing, and Whole Exome Sequencing in the Prenatal Diagnosis of Congenital Heart Disease: Detection Rates and Phenotypic Associations

Journal of Clinical Laboratory Analysis, EarlyView.
This study combined karyotyping, copy number variation sequencing, and whole‐exome sequencing to assess the value of genetic testing in the prenatal diagnosis of congenital heart disease (CHD) and to evaluate the relationship between genetic variants and prenatal phenotypes.

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Propagation of Chelidonium majus L. by somatic embryogenesis

, 2002
Direct somatic embryogenesis in celandine (Chelidonium majus L.) was achieved in epicotyl explants of seedlings after prolonged cultivation on Murashige and Skoog medium with or without plant growth regulators.

The Enteric Nervous System: An Integrative Hub From Development to Systemic Physiology

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Unlike a static hardwired circuit, the ENS continuously remodels its transcriptional programs and synaptic connectivity in response to three ecological forces: microbial metabolites, immune cell signals and enteroendocrine cues. ABSTRACT The enteric nervous system (ENS) constitutes the largest and most functionally autonomous subdivision of the ...

Molecular insights into somatic embryogenesis in Agave angustifolia: characterization of the AaSERK gene

Polibotánica
The Agave genus, with 204 species, including 163 natives to Mexico, is of paramount significance in ethnobotanical, ecological, and economic contexts. However, over-exploitation and uncontrolled harvesting of these plants endanger their survival due to ...
