The Roads to Haploid Embryogenesis

Plants, 2023
Although zygotic embryogenesis is usually studied in the field of seed biology, great attention has been paid to the methods used to generate haploid embryos due to their applications in crop breeding. These mainly include two methods for haploid embryogenesis: in vitro microspore embryogenesis and in vivo haploid embryogenesis.

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

Plant 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.

Matrix: a complex amalgam of structures and functions in tumor microenvironment

FEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Cystathionine γ-lyase inhibits mitochondrial oxidative stress by releasing H2S nearby through the AKT/NRF2 signaling pathway

Frontiers in Pharmacology
Cystathionine γ-lyase (CSE) is a major enzyme that produces hydrogen sulfide (H2S). Herein, we report how CSE plays a previously unknown role in regulating the antioxidant effects of the mitochondria in human umbilical vein endothelial cells by releasing

Desynchronizing Embryonic Cell Division Waves Reveals the Robustness of Xenopus laevis Development

Cell Reports, 2017
The early Xenopus laevis embryo is replete with dynamic spatial waves. One such wave, the cell division wave, emerges from the collective cell division timing of first tens and later hundreds of cells throughout the embryo.

Somatic embryogenesis and phase change in trees [PDF]

, 2011
The advantages of clonai plantations are obvious for a lot of tree species. Somatic embryogenesis is a clonai propagation method with the greatest potential for achieving this goal, especially if combined to genetic engineering.

Genome-Wide Reinforcement of DNA Methylation Occurs during Somatic Embryogenesis in Soybean

The Plant Cell, 2019
Rapid cell divisions that occur during somatic embryogenesis in soybean are accompanied by hyperactive DNA methylation pathways to ensure the maintenance of genome integrity over the short term.

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition

FEBS Open Bio, EarlyView.
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

A Quarter Century History of ATML1 Gene Research

Plants, 2021
The cloning of the ATML1 gene, encoding an HD-ZIP class IV transcription factor, was first reported in 1996. Because ATML1 mRNA was preferentially detected in the shoot epidermis, cis-regulatory sequences of ATML1 have been used to drive gene expression ...

Spatial mechanisms of gene regulation in metazoan embryos [PDF]

, 1991
The basic characteristics of embryonic process throughout Metazoa are considered with focus on those aspects that provide insight into how cell specification occurs in the initial stages of development.
