Abstract:
The somatic embryogenesis (SE) process is better suited to large-scale production and automation than other clonal propagation methods such as the rooting of cuttings. SE is becoming a key technique to promote the asexual industrialization of conifers. Furthermore, somatic embryos are an ideal material to study the molecular mechanism of conifer embryo development, as the processes of somatic and zygotic embryo development are very similar. This brief review introduces the culturing techniques of the SE process in conifers and outlines the progress and deficiencies in conifer SE research. Emphasis is placed on the patterning formation of conifer somatic embryos.
