Signaling Overview of Plant Somatic Embryogenesis

Frontiers in Plant Science, 2019
Somatic embryogenesis (SE) is a means by which plants can regenerate bipolar structures from a somatic cell. During the process of cell differentiation, the explant responds to endogenous stimuli, which trigger the induction of a signaling response and ...

Genes, proteins and other networks regulating somatic embryogenesis in plants

Journal of Genetic Engineering and Biotechnology, 2020
Somatic embryogenesis (SE) is an intricate molecular and biochemical process principally based on cellular totipotency and a model in studying plant development.

Development of support vector machine-based model and comparative analysis with artificial neural network for modeling the plant tissue culture procedures: effect of plant growth regulators on somatic embryogenesis of chrysanthemum, as a case study

Plant Methods, 2020
Optimizing the somatic embryogenesis protocol can be considered as the first and foremost step in successful gene transformation studies. However, it is usually difficult to achieve an optimized embryogenesis protocol due to the cost and time-consuming ...

Genome editing reveals a role for OCT4 in human embryogenesis

Nature, 2017
Despite their fundamental biological and clinical importance, the molecular mechanisms that regulate the first cell fate decisions in the human embryo are not well understood. Here we use CRISPR–Cas9-mediated genome editing to investigate the function of

The 2HA line of Medicago truncatula has characteristics of an epigenetic mutant that is weakly ethylene insensitive [PDF]

, 2016
BACKGROUND The Medicago truncatula 2HA seed line is highly embryogenic while the parental line Jemalong rarely produces embryos. The 2HA line was developed from one of the rare Jemalong regenerates and this method for obtaining a highly regenerable ...

Embryogenesis: Anchors away! [PDF]

Current Biology, 2007
It has long been appreciated that the oocyte cortex plays a key role in regulating fertilization and establishing embryonic polarity. Recent studies have identified the anti-phosphatase EGG-3 as a cortical anchor for regulatory proteins required for launching embryogenesis in Caenhorhabditis elegans.

Microspore embryogenesis: targeting the determinant factors of stress-induced cell reprogramming for crop improvement.

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 ...

Thermal effects on cephalopod energy metabolism - A case study for Sepia officinalis [PDF]

, 2008
Cephalopods are the largest, most active invertebrates and there is considerable evidence for their convergent evolution with fishes. However, most active cephalopods display standard and active metabolic rates that are several-fold higher than ...

Translocation of trace elements in the system "Mother-placenta-fetus" in rats with physiological pregnancy and under conditions of lead exposure.

Medičnì Perspektivi, 2014
Heavy metals are the second major environmental pollutants. Especially toxic is lead, increased content of which in the body of a pregnant determines the development of pregnancy, childbirth and postpartum period complications and is potentiated by ...
