AB [EN] Conifers are a group of woody plants with an enormous economic and ecological importance.Breeding programs are necessary to select superior varieties for planting, but they have manylimitations due to the biological characteristics of conifers. Somatic embryogenesis (SE) and de novoorganogenesis (DNO) from in vitro cultured tissues are two ways of plant mass propagation thathelp to overcome this problem. Although both processes are difficult to achieve in conifers, they offeradvantages like a great efficiency, the possibilities to cryopreserve the embryogenic lines, and theability of multiplying adult trees (the main bottleneck in conifer cloning) through DNO. Moreover, SEand DNO represent appropriate experimental systems to study the molecular bases of developmentalprocesses in conifers such as embryogenesis and shoot apical meristem (SAM) establishment. Someof the key genes regulating these processes belong to the WOX and KNOX homeobox gene families,whose function has been widely described in Arabidopsis thaliana. The sequences and roles of thesegenes in conifers are similar to those found in angiosperms, but some particularities exist, like thepresence of WOXX, a gene that putatively participates in the establishment of SAM in somaticembryos and plantlets of Pinus pinaster.
