Nitrogen uptake and assimilation in proliferating embryogenic cultures of Norway spruce-Investigating the specific role of glutamine. [PDF]

PLoS ONE, 2017
Somatic embryogenesis is an in vitro system employed for plant propagation and the study of embryo development. Nitrogen is essential for plant growth and development and, hence, the production of healthy embryos during somatic embryogenesis.

Pasta, a Versatile Transcriptomic Clock, Maps the Chemical and Genetic Determinants of Aging and Rejuvenation

Advanced Science, EarlyView.
Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.

AGL15 Promotion of Somatic Embryogenesis: Role and Molecular Mechanism

Frontiers in Plant Science, 2022
Plants have amazing regenerative properties with single somatic cells, or groups of cells able to give rise to fully formed plants. One means of regeneration is somatic embryogenesis, by which an embryonic structure is formed that “converts” into a ...

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

Advanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

Aspects related with the physic environment and the molecular characterization of the somatic embryogenesis

Biotecnología Vegetal, 2003
In the current work, a review on the influence of the in vitro environment in the morphogenetic process of the somatic embryogenesis is carry out, specifically the effect of certain gases accumulated in the gas phase of the culture vessel; such as oxygen,

BRASSINOSTEROIDS PREVENT THE CYTOKININ-INDUCED SOMATIC EMBRYOGENESIS OF COFFEEBRASSINOSTEROIDS PREVENT THE CYTOKININ-INDUCED SOMATIC EMBRYOGENESIS OF COFFEE (Coffea canephora)

Acta Biológica Colombiana
Plant somatic embryogenesis is a natural process that can be replicated in vitro by adding plant growth regulators. Reports in dicate that the application of brassinosteroids increased the number of embryos when added to the cytokinin-induced somatic ...

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Field Performance and Genetic Fidelity of Micropropagated Plants of Coffea canephora (Pierre ex A. Froehner)

Open Life Sciences, 2017
This study was conducted to compare the growth and yield of one of the commercial hybrid coffee cultivars (Coffea congensis x Coffea canephora) of robusta coffee established from somatic embryogenesis as well as conventional seedlings.

Maternal Exercise Rescues Embryonic Osteogenesis Impaired due to POLG Mutation Through a Potential Apelin‐ATF4 Axis

Advanced Science, EarlyView.
Maternal exercise (ME) increases apelin abundance across maternal and fetal tissues and is associated with improved fetal osteogenesis under POLG mutation‐induced mitochondrial dysfunction. Apelin‐APJ signaling is linked to enhanced mitochondrial function, Akt phosphorylation, and ATF4‐RUNX2 association, supporting coordinated fetal bone remodeling ...
