Distinct bacteria display genus and species-specific associations with mycobionts in paramo lichens in Colombia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lichens are complex symbiotic systems where fungi interact with an extracellular arrangement of one or more photosynthetic partners and an indeterminate number of other microbes. Recently, specific lichen-microbial community associations have been proposed. In this study, we aimed to characterize the differences in bacteria associated with closely related lichens, under a defined set of environmental conditions in Colombian paramos. Our goal was to determine if there is a correlation between microbiota and host divergence in lichen species belonging to the genus Sticta. We found that specific microbiota are defined by their mycobiont at the genus level. Further, distinct bacterial families show differences among the three studied genera, and specific amplicon sequence variants further discriminate among lichen species within each genus. A geographic component also determines the composition of these microbial communities among lichen species. Our functional analysis revealed that fungal partners play a key role in synthesizing complex polysaccharides, while bacterial-derived antioxidants and photoprotective mechanisms contribute to desiccation tolerance in lichens. These insights highlight the complex interactions within lichen symbioses that could be relevant in environments such as the paramo ecosystem.
