Prediction of temperature tolerance in Lilium based on distribution and climate data

Abstract

There are plenty publications providing guidance for resistant taxa selection by experimental researches while the number of experimental taxa is often restricted. In this study, we presented a concise method to predict the temperature tolerance of wild Lilium in China based on open access botanical and associated environmental datasets. We divided all taxa into five groups to present an overview of Lilium's adaptability to temperature stress. Furthermore, according to the environmental conditions, the prediction of heat and cold tolerance in Lilium was made based on the combined multi-sources data at taxon level. Thirteen taxa with potential temperature tolerance were predicted of 42 taxa. The results showed that not only is tolerance prediction created by large-scale data analysis possible, but that it may supplement traditional laboratory researches with a comprehensive list of taxa.

Tolerance potential of Lilium taxa to heat The mean TOF (A) and the maximum TOF (B) experienced by wild-growing Lilium species, as reported in our database. The change in color represented diverse tolerance to heat stress. The boxes and taxa name were colored every 5°C to make the figures more intuitively. See also Table S1.
