Abstract:
The data compiles different aspects of plant biology (e.g., anatomy, physiology, fitness and gene-expression) reported in scientific articles that experimentally explored the role of plant microbial symbionts in plant tolerance to chilling (0-15 degrees Celsius) and freezing (<0 degrees Celsius) conditions. Each variable included in the dataset is composed of at least four values, representing the mean of the measured variable with or without a given microbial symbiont and under control or cold conditions in a factorial design. The data were generated for a meta-analysis, and so the level of replication and standard deviation or standard error, plus other relevant information such as plant and microbial species, and source, are also included. The search from which the articles were obtained used ISI-web of Science used ENDOPH* AND COLD and MYCORRHIZA* AND COLD in both title and keyword fields from 1975 to 2019.

| Quality: | Data represents the reported numerical values as they appear in the published version of each article. Graphically-derived data could include a very small error as a result of digitalization; however, the data should not be biased to any particular experimental condition. | |
| Lineage: | After the initial selection of experimental articles that included all of the necessary data, we extracted the mean values of each variable that had been used to assess the performance of each plant species. We only used those variables for which it was also possible to estimate the level of replication and a pertinent dispersion value (i.e., standard deviation or standard error). The data were typically derived from tables and figures as reported in the published version of each article. When the figures were the only source of information, the mean and dispersion values were extracted using the online image processor WebPlotDigitizer v4.2 (https://automeris.io/WebPlotDigitizer/), which digitalizes Figures according to the given axes units, enabling the extraction of any point in the defined Cartesian space. | |
