Microbes Team Up Against Drought: Some Stronger, Some More Social
Fungal communities showed greater resistance but less resilience to drought than bacterial communities, though fungi were unexpectedly resilient in the first week of rewetting. Drought increased positive correlations among microbial taxa and networks based on positive correlations, but decreased overall network complexity suggesting a potential role for microbial communities in plant drought response.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Limited spatial and temporal scope
The study is limited to a single field site and a single growing season. The observed drought response patterns may not be generalizable to other environments or to longer time scales.
Single plant species
The study uses a single plant species (sorghum). Microbial community responses to drought might be different in more complex ecosystems.
Correlation-based co-occurrence
The co-occurrence network analysis is solely based on correlation. This is a limitation, as correlation may not fully reflect interaction between microbes.
Low power on testing dispersal limitation
Dispersal limitation is assumed not to be the driver based on a previous study and further tested by spatial distance between the two farthest points. However, it is likely that the limited power in the sampling scheme is not adequate to evaluate the effect of dispersal limitation.
Rating Explanation
This study provides valuable insights into the complex responses of microbial communities to drought. The combined analysis of community composition and co-occurrence networks reveals different patterns than traditional composition analysis alone, and highlighting the resilience of positive connections between functional microbial groups. The study identifies potential targets for microbial manipulation which suggests a possible approach to mitigating the impacts of drought on crops. However, the study is limited to a single field site, growing season, and crop species.
