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 O₂ dynamics" with the following abstract:

Adequate tissue O₂ supply is crucial for plant functioning. We therefore aimed at identifying environmental conditions and plant characteristics affecting plant tissue O₂ status. We extracted data and performed meta-analysis on > 1,500 published tissue O₂ measurements from 112 species. Tissue O₂ status ranged from anoxic conditions in especially roots, to > 53 kPa in submerged, photosynthesizing shoots. Using information-theoretic model selection, we identified ‘submergence’, ‘light’, ‘tissue type’ as well as ‘light × submergence’ interaction as significant drivers of tissue O₂ status. Median O₂ status was especially low (< 50% of atmospheric equilibrium) in belowground rhizomes, potato tubers and root nodules. Mean shoot and root O₂ was ~25% higher in light than in dark when shoots had atmospheric contact. However, light showed a significant interaction with submergence on plant O₂, 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 O₂ and shoot tissue O₂ correlated stronger in darkness than in light conditions. Although miniaturised Clark-type O₂ electrodes in particular have resulted in enhanced understanding of plant O₂ dynamics, the use of non-invasive methods is still lacking behind its widespread use in mammalian tissues.

We performed a structured and systematic literature search to identify studies reporting O₂ measurements in vegetative plant tissues. The search was conducted using the Web of Science BIOSIS database applying Boolean operators, as explained in detail in the Supplementary Materials. The search resulted in a final list of 129 studies published up until September 2022. We extracted each observation of plant tissue O₂ status and entered it into a database alongside information of plant species, tissue type, light conditions, submergence status, treatment, O₂ measurement technique, tissue excisions status, etc. if provided in the source.

The studies used for this review provide a wide range of ways to measure and report levels of plant tissue O₂. Details on data extractions, unit conversions, etc. are available in the related publication. Data were extracted from publication text, tables or graphs using ImageJ.
