Somatic embryogenesis (SE) in conifers is at the base of nearly allbiotechnology products that potentially might be developedincluding transgenic trees. SE is a powerful tool for clonalpropagation that has opened avenues for deployment of superiorclonally replicated planting stock in forest plantations. Althoughthe SE process can be managed for high efficiency there are stillseveral problems that require better understanding of underlyingcauses. One phenomenon, which occurs after the long-termculture of embryogenic tissue, particularly of pines, is the loss ofability to produce mature somatic embryos and consequentlyplants. Such unproductive cultures must be replaced, which is bothexpensive and undesirable. In an attempt to get an insight into... |

Advances in conifer biotechnology offer new opportunities in the field of vegetative propagation and geneticengineering. Development of clonal propagation methods, especially somatic embryogenesis (SE), has numerous potentialapplications. Owing to its efficiency in plant regeneration, coupled with the ease of long-term storage in liquid nitrogen, SEbecame an indispensable tool for accelerating the development of tree varieties and deployment. Early SE protocols weredeveloped for Picea species, however, when applied to Pinus species, especially at the somatic embryo maturation stage, theywere unsuccessful. It became apparent that pines required more research and development to bring the SE biotechnology to itspotential. This review emphasizes the most... |
