Effects of acidic conditions on the physiology of a green alga (Micractiniumsp.) before and after a 5-year interaction withTetrahymena thermophilain an experimental microcosm
Abstract:The mechanisms through which algae evolve physiological characteristics related to endosymbiotic associations with heterotrophic organisms remain unclear. We previously showed that a green alga (Micractinium sp.) was able to evolve a host (ciliate)-benefiting phenotype that prolonged the longevity of Tetrahymena thermophila in the absence of bacteria during a 5-year culture period in an experimental microcosm. Comparative experiments between the ancestral alga (i.e. original) and evolved algal clones of the sa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
