Data from: A meta-analysis of plant tissue O2 dynamics

<p><span>This dataset includes 1,567 recorded tissue O₂ levels from 112 plant species extracted from published literature. The data forms the basis of the publication "A meta-analysis of plant tissue </span><span>O₂</span><span> dynamics" with the following abstract:</span><br><br><span>Adequate tissue </span><span>O₂</span><span> supply is crucial for plant functioning. We therefore aimed at identifying environmental conditions and plant characteristics affecting plant tissue </span><span>O₂</span><span> status. We extracted data and performed meta-analysis on &gt; 1,500 published tissue </span><span>O₂</span><span> measurements from 112 species. Tissue </span><span>O₂</span><span> status ranged from anoxic conditions in especially roots, to &gt; 53 kPa in submerged, photosynthesizing shoots. Using </span><span>information-theoretic</span><span> model selection</span><span>, we identified 'submergence', 'light', 'tissue type' as well as 'light × submergence' interaction as significant drivers of tissue </span><span>O₂</span><span> status. Median </span><span>O₂</span><span> status was especially low (&lt; 50% of atmospheric equilibrium) in belowground rhizomes, potato tubers and root nodules. Mean shoot and root </span><span>O₂</span><span> was ~25% higher in light than in dark when shoots had atmospheric contact. However, light showed a significant interaction with submergence on plant </span><span>O₂</span><span>, with a submergence-induced 44% increase in light, compared with a 42% decline in dark, relative to plants with atmospheric contact. During submergence, ambient water column </span><span>O₂</span><span> and shoot tissue </span><span>O₂</span><span> correlated stronger in darkness than in light conditions. Although miniaturised Clark-type </span><span>O₂</span><span> electrodes in particular have resulted in enhanced understanding of plant </span><span>O₂</span><span> dynamics, the use of non-invasive methods is still lacking behind</span> <span>its widespread use in</span><span> mammalian tissues. </span></p>
