Stat3/Cdc25a-dependent cell proliferation promotes embryonic axis extension during zebrafish gastrulation [PDF]

open access: yes, 2017
Cell proliferation has generally been considered dispensable for anteroposterior extension of embryonic axis during vertebrate gastrulation. Signal transducer and activator of transcription 3 (Stat3), a conserved controller of cell proliferation ...

Genetic proof of chromatin diminution under mitotic agamospermy [PDF]

open access: yesarXiv, 2013
The previously published data are examined on the base of the hypothesis about existence of differential polyteny of chromosomes and excess chromatin diminution during the first stages of embryogenesis. It has been concluded that available data provide the genetic proof that chromatin diminution is one of the mechanisms underlying the origin of ...

Possibilities and limitations of vegetative propagation in breeding and mass propagation of Norway spruce [PDF]

open access: yes, 2003
The use of vegetative mass propagation in practical forestry with Norway spruce (Picea abies (L.) Karst.) is limited at present, although its potential to deliver high genetic gains is obvious.

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

open access: yes, 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 ...

Gastrulation and hatch as critical thermal windows for salmonid embryo development

open access: yesRiver Research and Applications, Volume 39, Issue 1, Page 46-53, January 2023., 2023
Abstract Climate change and impoundment increase river temperatures, shifting the bioclimatic envelope in which freshwater biota have evolved and increasing salmonid egg mortality. To mitigate this, conservation flows from reservoirs are often implemented to maintain favourable water temperatures downstream from impoundments throughout salmonid embryo ...

Collective mechanics of embryogenesis: Formation of ventral furrow in Drosophila [PDF]

open access: yesarXiv, 2011
We propose a 2D mechanical model of the ventral furrow formation in Drosophila that is based on undifferentiated epithelial cells of identical properties whose energy resides in their membrane. Depending on the relative tensions of the apical, basal, and lateral sides, the minimal-energy states of the embryo cross-section includes circular, elliptical,

Alternative Splicing as a Regulator of Early Plant Development

open access: yesFrontiers in Plant Science, 2018
Most plant genes are interrupted by introns and the corresponding transcripts need to undergo pre-mRNA splicing to remove these intervening sequences.

Cyclization of Short Peptides Designed from Late Embryogenesis Abundant Protein to Improve Stability and Functionality

open access: yesChemBioChem, EarlyView.
Late embryogenic abundant (LEA) peptides are short, disordered peptides that enhance Escherichia coli′s drought stress tolerance. Cyclization of LEA peptides can further improve their properties, such as anti‐desiccation, thereby expanding their potential applications Abstract LEA peptides, which are designed based on late embryogenic abundant (LEA ...
