In vitro callogenesis essays to induce somatic embryogenesis of the Tunisian chickpea

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
The present study was the first report on the somatic embryogenesis of the Tunisian chickpea (Cicer arietinum L.) particularly supposed to be recalcitrant and difficult to manipulate in vitro.

Comparative Analysis of Nuclear Transfer Embryo Derived Mouse Embryonic Stem Cells. Part I: Cellular characterization [PDF]

, 2012
Embryonic stem cells derived from nuclear transfer embryos (ntESCs) are particularly valuable for regenerative medicine, as they are a patient-specific and histocompatible cell source for the treatment of varying diseases.

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

FEBS 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 ...

Long-Term Maintainable Somatic Embryogenesis System in Alfalfa (Medicago sativa) Using Leaf Explants: Embryogenic Sustainability Approach

Plants, 2019
Alfalfa (Medicago sativa) is one of the most important forage legume crops because of its mass production and high feeding value. It originated in Asia and is one of the most ancient plants cultivated throughout the world as a fodder.

Cryopreservation of sugarcane somatic embryos.

Cryo letters, 2008
In this paper, we compared three vitrification-based cryopreservation techniques, viz. vitrification, encapsulation-vitrification and droplet-vitrification for cryopreserving sugarcane somatic embryos. Viability of somatic embryos was evaluated by measuring electrolyte leakage and by regrowth on recovery medium.

Control of pluripotency during the oocyte-to-embryo transition in caenorhabditis elegans [PDF]

, 2015
The germline of Caenorhabditis elegans has been used as a model system to study the control of pluripotency in germ cells: through the mean of a genetic screen, from which most of the results of this thesis derived, different factors involved in the ...

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

FEBS 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.

Somatic Embryogenesis and Plant Regeneration from Commercial Soybean Cultivars

Plants, 2019
The efficient regeneration of plants from commercial genotypes is a pre-requisite for successful genetic transformation, to apply modern crop improvement techniques such as CRISPR-based genome editing. Plant regeneration through the somatic embryogenesis

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

Tree 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 ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
