Embryonic Development in Two High‐Elevation Oviparous Lizard Species: Contrasting Strategies for Coping With Cold Climates

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Understanding how species respond to local climates is crucial for predicting their responses to climate change. The cold climate of high elevations constitutes a physiological challenge for reptiles, especially during the embryonic stages of oviparous species, because embryos have limited ability to thermoregulate behaviorally. To examine how

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

EVALUATION OF THE GENETIC STABILITY OF PLANTS OBTAINED VIA SOMATIC EMBRYOGENESIS IN Chrysanthemum × grandiflorum (Ramat./Kitam.)

Acta Scientiarum Polonorum: Hortorum Cultus, 2015
Genetic and phenotypic stability of plants obtained via somatic embryogenesis may be disrupted. The reason can be an indirect regeneration of somatic embryos via callus or a high concentration of growth regulators added at the induction stage of somatic

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

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

Biotecnología 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.

Establishment of a glucocorticoid inducible system for regulating somatic embryogenesis in Liriodendron hybrids

Forestry Research
The precise expression of transcription factors (TFs) is crucial for plant growth and development, especially during somatic embryogenesis. However, conventional overexpression approaches, commonly used for functional genetics, can lead to deleterious ...

Somatic embryogenesis and virus elimination in Citrus

, 2013
Citrus represents one of the most important fruit crops worldwide, in terms of economic value and human nutrition. Among fruit tree species, Citrus is the most affected by graft-transmissible pathogens, mainly represented by virus and virus-like agents ...

Dynamics of Size and Shape Variation During Embryonic Development in the Balkan Crested Newt

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Morphological variance in Triturus ivanbureschi embryos fluctuates during the tailbud phase, coinciding with developmental arrest caused by the balanced lethal system. Prehatching embryos show uniform variance. Our study reveals dynamics of morphological variability during early development and provides a baseline for further studies.

The WOX Genes from the Intermediate Clade: Influence on the Somatic Embryogenesis in Medicago truncatula

Plants
Transcription factors from the WOX family are well-known regulators of cell proliferation and differentiation in plants. Herein, we focused on several WOX genes from the intermediate clade and checked their impact on somatic embryogenesis using the model
