Abstract
Wounds stimulate diverse responses in plants, including mainly modifications in the differentiation fate of the injured and surrounding tissues, leading to the development of barriers against the attack of opportunistic pathogens and pests, healing or, in certain cases, regeneration of damaged organs or de novo generation of organs. The healing capacity is usually higher in angiosperms than gymnosperms. Specifically, re-sprouting is a relatively common feature in angiosperms, very important in post-fire recovery, after predation by herbivores, or even after logging. In conifers, resin from constitutive and traumatic channels covers the surface of the wound, preventing the entrance and development of fungi and other pathogens, but also impeding the eventual proliferation of immature xylem cells and the formation of a callus, as occurs in angiosperms. Thus, wounds in conifer stems must be sealed exclusively from the borders, presumably from vascular cambium, being a much slower process, which very often remains unconcluded. Pinus canariensis Chr. Sm. ex D.C. shows an effective wound-healing process and being the only Pinaceae in the Old World able to resprout.
