Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Metabolite profiling of somatic embryos of Cyclamen persicum in comparison to zygotic embryos, endosperm and testa

open access: yesFrontiers in Plant Science, 2015
Somatic embryogenesis has been shown to be an efficient in vitro plant regeneration system for many crops such as the important ornamental plant Cyclamen persicum, for which this regeneration pathway of somatic embryogenesis is of interest for the ...

Polyamine profiles and biosynthesis in somatic embryo development and comparison of germinating somatic and zygotic embryos of Norway spruce [PDF]

open access: yesTree Physiology, 2009
The polyamine (PA) contents and activities of PA biosynthetic enzymes in Norway spruce somatic embryos [Picea abies L. (Karst.), genotype AFO 541] were studied in relation to anatomical changes during their development, from proliferation to germination, and changes in these variables associated with the germination of mature somatic and zygotic ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Somatic embryos formation from immature cotyledons in Phaseolus vulgaris cv. CIAP 7247

open access: yesBiotecnología Vegetal, 2011
Common bean, like most of legumes, is recalcitrant to in vitro culture, so the establishment of a regeneration procedure via somatic embryogenesis in this specie has not been possible.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Plant regeneration of southern Adriatic iris by somatic embryogenesis [PDF]

open access: yesArchives of Biological Sciences, 2009
A simple protocol has been developed for plant regeneration by somatic embryogenesis of Southern Adriatic iris (Iris pseudopallida Trinajstić), an endemic species of the Balkan Peninsula.

The Potentiality of the Embryo and the Somatic Cell [PDF]

open access: yesMetaphilosophy, 2014
AbstractRecent arguments on the ethics of stem cell research have taken a novel approach to the question of the moral status of the embryo. One influential argument focuses on a property that the embryo is said to possess—namely, the property of being an entity with a rational nature or, less controversially, an entity that has the potential to acquire

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Influence of maltose and sucrose on somatic embryos maturation of Glycine max cv. 'Incasoy-27'

open access: yesBiotecnología Vegetal, 2019
The somatic embryogenesis in soybean crop (Glycine max)has as limitation the low percentage of conversion to plant that is obtained, attributed to the presence of somatic embryos with abnormal morphologies during the maturation phase.
