Abstract:
Somatic embryogenesis (SE) is a developmental process in which somatic cells undergo dedifferentiation to become plant stem cells, and redifferentiation to become a whole embryo. SE is a prerequisite for molecular breeding and is an excellent platform to study cell development in the majority of plant species. However, the molecular mechanism involved in M. sativa somatic embryonic induction, embryonic and maturation is unclear. This study was designed to examine the differentially expressed genes (DEGs) and miRNA roles during somatic embryonic induction, embryonic and maturation. The cut coty

Differential gene expression profiles of various cannabis calli including non-embryogenic and embryogenic (i.e., rooty and embryonic callus) were examined in this study to enhance our understanding of callus development in cannabis and facilitate the development of improved strategies for plant regeneration and biotechnological applications in this economically valuable crop. A total of 6118 genes displayed significant differential expression, with 1850 genes downregulated and 1873 genes upregulated in embryogenic callus compared to non-embryogenic callus.

Abstract:
The somatic embryogenesis (SE) process of plants is regulated by exogenous hormones. During the SE, different genes sensitively respond to hormone signals through complex regulatory networks to exhibit plant totipotency. When cultured in indole-3-butyric acid (IBA) concentration gradient medium supplemented with 0 mg dm−3, 0.025 mg dm−3, and 0.05 mg dm−3 IBA, the callus differentiation rate first increased then decreased in cotton. To characterize the molecular basis of IBA-induced regulating SE, transcriptome analysis was conducted on embryogenic redifferentiation. Upon the examination of the

Abstract:
Plant miRNAs are short non-coding RNAs that mediate the repression of hundreds of genes. The basic plant body plan is established during early embryogenesis, and recent results have demonstrated that miRNAs play pivotal roles during both embryonic pattern formation and developmental timing. Multiple miRNAs appear to specifically repress transcription factor families during early embryogenesis. Therefore miRNAs probably have a large influence on the gene regulatory networks that contribute to the earliest cellular differentiation events in plants.

AbstractEmbryogenic callus induction and regeneration are useful in many aspects of plant biotechnology, especially in the functional characterization of economically important genes.

The development of safe and efficient gene delivery systems in pluripotent human embryonic stem cells (hESc) is essential to realising their full potential for basic and clinical research.

Similar to endogenous chromosomes, HAC are capable of gene expression, replication and segregation during cell division. Unlike retroviral-mediated gene delivery vectors, HAC do not integrate into the host genome and can encompass large genomic regions fo

Therefore, this technique, along with in vitro culture methods such as somatic embryogenesis (SE), can introduce genetic variation in otherwise genetically homogeneous populations.
