Sustainable and efficient protocols for in vitro germination and antioxidants production from seeds of the endangered species Araucaria araucana [PDF]
Journal of Genetic Engineering and Biotechnology, 2021 Background The Pehuén or Monkey puzzle tree (Araucaria araucana) is an evergreen coniferous tree, which has been historically used for social, medicinal, and nutritional purposes. We have recently showed the value of A. araucana seeds as a rich source of

Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions. [PDF]
Environ Microbiol RepSoil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...
