Characterization of cellulases of fungal endophytes isolated from Espeletia spp.

Journal of Microbiology, 2012
Endophytes are microorganisms that asymptomatically invade plant tissues. They can stimulate plant growth and/or provide defense against pathogen attacks through the production of secondary metabolites. Most endophyte species are still unknown, and because they may have several applications, the study of their metabolic capabilities is essential.

Desiccation and Freezing Phenomena for Plants with Large Water Capacitance — Cacti and Espeletias

1992
Cacti and espeletias are native to dissimilar habitats, although the two groups must cope with several similar environmental constraints. Cacti, which are succulent plants that utilize crassulacean acid metabolism (CAM), grow in habitats characterized by long periods of drought (Ting 1985; Nobel 1988a).
