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.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Indirect somatic embryogenesis of Swietenia macrophylla King in semisolid culture medium

Biotecnología Vegetal, 2010
Biotechnological techniques are an alternative to propagate Swietenia macrophylla King. However, micropropagation by organogenesis in this species has been little or not developed due to big microbial contamination and low indexes of in vitro plants ...

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 ...

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

Advanced Science, EarlyView.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

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 ...

Somatic embryogenesis induction and plant regeneration in date palm (Phoenix dactylifera L.) cv. Bouskri

African and Mediterranean Agricultural Journal - Al Awamia, 2022
The effects of different medium components on somatic embryogenesis induction, and somatic embryo maturation and conversion were evaluated in date palm cv. Bouskri. Adventitious bud segments were used to induce somatic embryogenesis.

Functional Mapping of Neurodevelopmental Disease Pathways to Key Neurodevelopmental Processes Represented in the Developmental Neurotoxicity In Vitro Testing Battery

Advanced Science, EarlyView.
Human‐relevant methods are essential for modern chemical safety assessment. This study helps define the capabilities and boundaries of an in vitro testing battery for developmental neurotoxicity by exploring its biological applicability domain. By linking neurodevelopmental disease‐related pathways to key neurodevelopmental processes, the work enhances

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,

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.
