Expression of Genes Involved in ABA and Auxin Metabolism and LEA Gene during Embryogenesis in Hemp
The level of phytohormones such as abscisic acid (ABA) and auxins (Aux) changes dynamically during embryogenesis. Knowledge of the transcriptional activity of the genes of their metabolic pathways is essential for a deeper understanding of embryogenesis ...

Plant embryo development is a complex process that includes several coordinated events. Maize mature embryos consist of a well-differentiated embryonic axis surrounded by a single massive cotyledon called scutellum. Mature embryo axis also includes lateral roots and several developed leaves.

Embryogenesis of the peristaltic reflex [PDF]
Key points Neurogenic gut movements start after longitudinal smooth muscle differentiation in three species (mouse, zebrafish, chicken), and at E16 in the chicken embryo. The first activity of the chicken enteric nervous system is dominated by inhibitory neurons. The embryonic enteric nervous system electromechanically couples circular and longitudinal

ATACing Somatic Embryogenesis [PDF]
How does auxin induce somatic embryogenesis? In this issue of Developmental Cell, Wang et al. uncover a regulatory role for auxin in the dynamics of chromatin accessibility and gene expression, which is critical for the establishment of developmental time-specific transcriptional regulatory networks orchestrating somatic-to-embryonic cell reprogramming

The small intestinal mucosa and its stem cells
In the first part of this review a brief summary of the embryology and histology of the gastrointestinal tract is provided. In the second part intestinal stem cells (ISCs) are discussed. Several signaling pathways play a crucial role in the crypt base in
