Age-dependent biological characteristics of embryonal mass of maritime pine in relation to the embryogenic potential

Abstract:

Somatic embryogenesis (SE) in conifers is at the base of nearly all biotechnology products that potentially might be developed including transgenic trees. SE is a powerful tool for clonal propagation that has opened avenues for deployment of superior clonally replicated planting stock in forest plantations. Although the SE process can be managed for high efficiency there are still several problems that require better understanding of underlying causes. One phenomenon, which occurs after the long-term culture of embryogenic tissue, particularly of pines, is the loss of ability to produce mature somatic embryos and consequently plants. Such unproductive cultures must be replaced, which is both expensive and undesirable. In an attempt to get an insight into the differences between young, primary lines of embryonal mass of maritime pine that produced somatic embryos and the same lines of significantly increased …
