Journal of Experimental Botany, 2019 Under stress, isolated microspores are reprogrammed in vitro towards embryogenesis, producing doubled haploid plants that are useful biotechnological tools in plant breeding as a source of new genetic variability, fixed in homozygous plants in only one ...

Speed of reaction diffusion in embryogenesis [PDF]
, 2007 Reaction diffusion systems have been proposed as mechanisms for patterning during many stages of embryonic development. While much attention has been focused on the study of the steady state patterns formed and the robustness of pattern selection, much ...

Inferring simple but precise quantitative models of human oocyte and early embryo development [PDF]
arXiv, 2021 Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature of oogenesis and embryogenesis.

A transcriptional view on somatic embryogenesis
Regeneration, 2017 Somatic embryogenesis is a form of induced plant cell totipotency where embryos develop from somatic or vegetative cells in the absence of fertilization.

BMP Signaling: Lighting up the Way for Embryonic Dorsoventral Patterning
Frontiers in Cell and Developmental Biology, 2021 One of the most significant events during early embryonic development is the establishment of a basic embryonic body plan, which is defined by anteroposterior, dorsoventral (DV), and left-right axes.

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.

Regulatory principles governing the maternal-to-zygotic transition: insights from Drosophila melanogaster [PDF]
Open Biology, 2018 The onset of metazoan development requires that two terminally differentiated germ cells, a sperm and an oocyte, become reprogrammed to the totipotent embryo, which can subsequently give rise to all the cell types of the adult organism.

Embryogenesis and the glyoxylate cycle [PDF]
FEBS Letters, 1980 The key catalysts of the glyoxylate cycle, isocitrate lyase (EC 4.1.3.1) and malate synthase (EC 4.1.3.2), have been investigated in a variety of tissues [l-3]. In general, the biological a~im~ation of acetate units or the conversion of fatty acids to carbohydrates requires function of glyoxylate cycle [4-61.

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.
