Agave fourcroydes (henequén) is a plant used for the extraction of hard fiber from its leaves. Due to its long-life cycle, it is very difficult to genetically improve. Somatic embryogenesis (SE) is a very useful micropropagation technique, that can be used for genetic improvement programs and increase the micropropagation of this species. SE is a morphogenic process by which somatic embryos are generated from somatic cells reprogramming. To initiate the regeneration program, the loss of cell-cell communication is suggested to be important. The Thin Cell Layer (TCL) technique allows for the isolation of specific cell or tissue layers, and in conjunction with strictly controlled growth conditions, may lead to the in vitro induction of specific morphogenic programs. Here, we describe a new protocol for the induction of somatic embryogenesis through TCL culture technique, from stem of elite clonal A. fourcroydes vitroplants previously generated through micropropagation of adventitious shoots.

DNA methylation, catalyzed by DNA methyltransferases (DNMT), plays pivotal role in regulating embryonic development, gene expression, adaption to environmental stress, and maintaining genome integrity. DNMT family consists of DNMT1, DNMT3A, DNMT3B, and the enzymatically inactive DNMT3L. DNMT3A and DNMT3B establish novel methylation patterns maintained by DNMT1 during replication.

Unlike differentiated somatic cells, which possess elongated mitochondria, undifferentiated cells, such as those of preimplantation embryos, possess round, immature mitochondria. Mitochondrial morphology changes dynamically during cell differentiation in a process called mitochondrial maturation. The significance of the alignment between cell differentiation and mitochondrial maturity in preimplantation development remains unclear.

Gamma-Retroviral (RVVs) and lentiviral vectors (LVVs) represent indispensable tools in somatic gene therapy, mediating the efficient, stable transfer of therapeutic genes into a variety of human target cells. LVVs, in contrast to RVVs, are capable of stably genetically modifying non-proliferating target cells, making them the superior instrument in cell and gene therapy. To date, the LVV manufacturing process employs human embryonic kidney cells (HEK293) and derivatives thereof transiently transfected with multiple plasmids encoding the required viral vector components.

Background: Identifying markers or genes crucial for growth traits in Zhongwei goats is pivotal for breeding. Pinpointing genetic factors linked to body size gain enhances breeding efficiency and economic value. In this study, we used the MGISEQ-T7 platform to re-sequence 240 Zhongwei goats (133 male; 107 female) belonging to 5 metrics of growth traits at different growth stages (40 days and 6 months, here in after referred to as 40d and 6 m), namely, Body Weight (BW), Body Height (BH), Body Length (BL), Chest Circumference (CC), Tube Circumference (TC) were examined.

Maintenance and breeding of experimental organisms are fundamental to life sciences, but both initial and running costs, and hands-on zootechnical demands can be challenging for many laboratories. Here, we first aimed to further develop a simple protocol for reliable inland culture of tunicate model species of the genus. We cultured both and in controlled experimental conditions, with a focus on dietary variables, and quantified growth and maturation parameters.
