Mature seeds for in vitro sanitation of the Grapevine leafroll associated virus (GLRaV-1andGLRaV-3) from grape (Vitis vinifera L.)

open access: yesSpanish Journal of Agricultural Research, 2015
The conservation of old grapevine varieties is important since they are adapted to specific climate conditions and may carry genes interesting to breeders.

Expression of Genes Involved in ABA and Auxin Metabolism and LEA Gene during Embryogenesis in Hemp

open access: yesPlants, 2022
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 ...

Essential factors for in vitro regeneration of rose and a protocol for plant regeneration from leaves

open access: yesHorticultural Science, 2018
In vitro propagation of Rosa hybrida, L. cv. 'Eiffel Tower' was improved by the addition of thidiazuron (TDZ) and silver nitrate (AgNo3) to the culture medium.

Maize Embryogenesis

open access: yes, 2008
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.

The Role of Mitochondria in Human Fertility and Early Embryo Development: What Can We Learn for Clinical Application of Assessing and Improving Mitochondrial DNA?

open access: yesCells, 2022
Mitochondria are well known as ‘the powerhouses of the cell’. Indeed, their major role is cellular energy production driven by both mitochondrial and nuclear DNA.

Embryogenesis of the peristaltic reflex [PDF]

open access: yesThe Journal of Physiology, 2019
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]

open access: yesDevelopmental Cell, 2020
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

open access: yesJournal of Pediatric and Neonatal Individualized Medicine, 2016
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
