First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

open access: yesThe Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Cloning of the Coffea canephora SERK1 promoter and its molecular analysis during the cell-to-embryo transition

open access: yesElectronic Journal of Biotechnology, 2018
Background: Somatic embryogenesis receptor-like kinase 1 (SERK1) is a cell membrane receptor active in different plant tissues and involved in cell differentiation activities including somatic embryogenesis.

Biomechanical strain patterns in Meckel's cartilage underlie mandibular variation in FGFR2 mouse models

open access: yesThe Anatomical Record, EarlyView.
Abstract Sequence variations in fibroblast growth factor receptor 2 (FGFR2) are associated with craniosynostosis syndromes, disrupting craniofacial development, yet early mandibular alterations remain poorly characterized. This study examined Meckel's cartilage (MC) and mandibular morphology in mouse models of Apert (Fgfr2+/P253R) and Crouzon ...

In vitro regeneration of some Iranian alfalfa (Medicago sativa L.) genotypes via somatic embryogenesis [PDF]

open access: yesZīst/shināsī-i Giyāhī-i Īrān, 2014
An effective in vitro regeneration system is one of the prerequisites for genetic manipulation of alfalfa (Medicago sativa L.) varieties and genotypes. In this research, somatic embryogenesis of four alfalfa genotypes, 6-18 (synthetic), 4-14 (Kara Yonje-

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Multi‐omics analyses reveal epigenomics basis for cotton somatic embryogenesis through successive regeneration acclimation process

open access: yesPlant Biotechnology Journal, 2018
Summary Plant regeneration via somatic embryogenesis is time‐consuming and highly genotype‐dependent. The plant somatic embryogenesis process provokes many epigenetics changes including DNA methylation and histone modification.

Genetic control of somatic embryogenesis in alfalfa

open access: yes, 1992
The genetic control of somatic embryogenesis in alfalfa (Medicago sativa L.) was studied using one nonembryogenic and three embryogenic genotypes: A70-34, a selection from 'Rangelander'; RA3, a selection from 'Regen-S'; and C2-4, a selection from a ...

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Rapid genotype “independent” Zea mays L. (maize) transformation via direct somatic embryogenesis

open access: yesIn vitro cellular & developmental biology. Plant, 2018
Constitutive expression of the Zea mays L. (maize) morphogenic transcription factors Baby Boom (Bbm) and Wuschel2 (Wus2) in maize can not only greatly increase transformation efficiency but can also induce phenotypic abnormalities and sterility.

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...
