Estudio metabolómico preliminar de Espeletia grandiflora Humb. & Bonpl. (Compositae) a lo largo de un gradiente altitudinal y fenológico del Parque Nacional Natural Chingaza

Frailejones (subtribu: Espeletiinae) are a successful plant group belonging to the Asteraceae family that have adapted to the dynamic and heterogenous environmental conditions of paramos, which vary in temporal and spatial scales [1]. However, the variability associated to the production ofsecondary metabolites in response to environmental conditions remains unexplored [2]. A preliminary metabolomic approach was used to demonstrate the variability associated to the production of secondary metabolites in Espeletia grandifloraduring development and in an altitudinal gradient. It was found that the developmental stage has a major influence over the metabolic profile than the altitudinal gradient. It is concluded that the variability associated to the production of secondary metabolites is a functional trait of E. grandiflorathat could determine their adaptability and survival in paramo ecosystems and the importance of the first stages of life in the consolidation of a chemical response to abiotic stress is highlighted [3].
