In the in vitro cloning of specific individuals of woody species, a challenge can be the low viability of explants collected from old mature donor trees due to the recalcitrance of their plant material. Other factors, such as the auxin–cytokinin balance, must also be considered. We investigated how in vitro conditions and donor age can modulate the regeneration capacity, morphophysiology, and DNA methylation of Quercus robur ....

The discovery of nucleic acids stands as a paramount achievement in the history of scientific endeavors. By applying transformative advancements in the fields of chemistry and physics to biological systems, researchers unveiled the enigmatic nature of life. Notably, messenger RNA (mRNA) emerged as a crucial player in this profound revelation, serving as a transient intermediary for genetic information transfer between genes an...
