Boxplots are great when different data distributions matter to your research question, but they’re used a lot (by default) in #rstats when the goal is to show treatment means. If your model focuses on mean responses, a simple mean ± SD (or CI) bar plot is nicer 😗

Labeling chambers are up and running so these dual-mycorrhizal plants are incorporating 13-CO2 to measure how much they give their fungal mutualists

Integrating ‘cry for help’ strategies for sustainable agriculture
Plants recruit specific soil microbes through a sophisticated ‘cry for help’ strategy to mitigate environmental stresses. Recent advances highlight the potential of leveraging this mechanism to develop microbe-based approaches for enhancing crop health, but challenges remain in refining the criteria and conceptual frameworks to effectively investigate and harness these plant–microbe interactions.

Cool new paper about diversity effects on mycorrizal resource exchange out in new phyt!!!
We found that AMF gave more P to plants at lower C:P at higher AMF diversity.
We grew three plant communities of either legumes, forbs or grasses with a gradient of AMF species richness and radiolabeled the AMF P pool and plant C pool (chamber in pics)

Cool paper by Kodama et al...a bryophyte makes Strigolactones (SLs) to recruit mycorrhiza, but doesn't use SL as a growth hormone, showing that SLs first evolved in the ancestor of land plants to initiate symbiosis. Love being reminded that symbiosis is everything.

want 2 combine datasets produced by different 'omics methods (eg, 16S + ITS) & analyze interkingdom interactions? 🦠🍄
Brunner et al 2024 show that clr-normalizing data separately + accommodating sparsity reduce error, then describe this error "signature" so you can spot it

Fungal endophytes could potentially promote plant resilience to climate change. However, across 3 warming experiments (differing in age/species/climate), warming disrupted plant-fungal endophyte symbiosis, with stronger effects in leaves than roots.
