Somatic embryogenesis in Pinus radiata
Somatic embryogenesis of Pinus radiata has been seen as an attractive alternative to traditional propagation methods. This is due to its potential for high multiplication rates and rejuvenation, as well as its compatibitity with molecular techniques. To date no commercial production of somatic …

Transcriptional divergence during cichlid embryogenesis
… traits likely being established during early embryogenesis. A central question that remains is how variation is generated during development. Moreover, cichlids are shown to have very low average nucleotide diversity within and between species. This low variation at the genomic level cannot …

mRNA localization in Caenorhabditis elegans embryogenesis
From guiding cell specification to regulating protein output, post-transcriptional regulation of mRNA is essential for life. As a result, many mechanisms underlying post-transcriptional regulation are highly conserved across the kingdoms of life. As the spatial resolution of microscopy and …

PROPAGATION OF PLANTS BY SOMATIC EMBRYOGENESIS
… reduced by utilising the phenomenon of somatic embryogenesis for plant regeneration (Jones, 1984, Biochem. Soc. Symp. 98: 222-232). Although many publications describe how mbryogenesis may be induced in particular cases (reviewed by Williams and Maheswaran, 1986, Ann. Bot. 57: 449-462), the …

Transcriptome Analysis of Sea Lamprey Embryogenesis
… and embryos at different time points during embryogenesis were extracted and then subjected to Next Generation Sequencing (NGS). Approximately 14,000 transcripts in total were detected. Data from each stage was analyzed using log<sub>2</sub> values to determine significant gene expression …

The Regulation of UHRF1 during Mammalian Embryogenesis
Mammalian embryogenesis comprises two independent instances of global DNA demethylation that each coincide with an increase in developmental potential: firstly during the development of the inner cell mass from the gametes, and secondly during the development of primordial germ cells. Although some …

Pluripotency and patterning in nonhuman primate embryogenesis
… property of the early embryo. However, primate embryogenesis differs in anatomical architecture, developmental timing, and molecular configuration. Obvious ethical considerations limit human embryo research, thus nonhuman primates offer an opportunity to unravel primate-specific features of …

MOLECULAR ASPECTS OF DIRECT SOMATIC EMBRYOGENESIS IN ALFALFA (MEDICAGO)
Somatic embryogenesis follows the developmental pattern of the zygote in vitro so it provides a model for early plant development which is more accessible for experimental manipulations. Most of the fundamental research in this area has exploited indirect embryogenic systems which require cells to …

Characterizing PIAS1 Function During Embryogenesis and Lung Cancer Progression
The main focus of this work is to provide a better understanding about the function of small ubiquitin like modifiers (SUMO) conjugating enzymes in eukaryotes during embryonic organogenesis, tissue differentiation and human tumor progression; with a focus on non-small cell lung cancers (NSCLC). The …

Propagation of asparagus (Asparagus officinalis L.) via somatic embryogenesis
This thesis reports the development of somatic embryogenesis system for asparagus (Asparagus officinalis L.). Somatic embryogenesis is important as an efficient system for clonal propagation. To achieve this technique, the first step is the initiation of callus followed by the induction of the …

Bioimaging of animal embryogenesis: mathematical methods and computational algorithms
Some fundamental biological processes such as embryonic development have been preserved during evolution and are common to species belonging to different phylogenetic positions, but are nowadays largely unknown. The understanding of cell morphodynamics leading to the formation of organized spatial …

Interleukin-6 and its Contribution to Embryogenesis in Cattle
… are invaluable for our understanding of embryogenesis and the processes that regulate it. However, extensive research has also highlighted that in vitro produced embryos negatively differ from their in vivo counterparts in various ways. Not surprisingly, there is ~20% decrease in …

Interaction of akirin and pannier during embryogenesis of Drosophila melanogaster
<p><em>Akirin</em>, a highly conserved protein found in nearly all eukaryote species, is a transcriptional cofactor that has been known to play a critical role in the muscular development in <em>Drosophila</em>. In this study, we identified and analyzed the genetic interaction of <em>akirin …

piRNA-dependent transcriptional gene silencing during Drosophila oogenesis and embryogenesis
… and the PICTS complex during early Drosophila embryogenesis. Piwi showed no zygotic transcription in somatic cells but strong maternal deposition and localised not only to pole cells, the germ line precursors, but was also strongly enriched in somatic nuclei. Additionally, the PICTS complex was …

Function of core promoters in differential gene regulation during embryogenesis
The core promoter is the ultimate target of all transcriptional regulatory processes. The recently discovered diversity of core promoters and basal transcription factors suggests a regulatory role in differential gene expression. However, the direct contribution of the core promoter remains poorly …

Characterising functions of long non-coding RNAs in Drosophila embryogenesis
… the impact of lncRNAs loss of function during embryogenesis of Drosophila melanogaster. I chose this model organism for its well documented developmental stages and the plethora of established tools available to facilitate genetic studies. Twenty-two lncRNA candidates were chosen based on their …
