A database of plant heat tolerances and methodological matters

Abstract

Motivation Plant heat tolerance data are increasingly valued for their potential to help increase our understanding of species’ responses to extreme temperatures, but these efforts are hindered by methodological inconsistencies and missing contextual information. To address this issue, we collated data that compiles heat tolerance estimates and documents key sources of variation attributable to taxonomy, methodology, geography, and cultivation to improve data clarity and usability. This resource is designed to catalyze more rigorous and ecologically meaningful syntheses by enabling researchers to identify, account for, and test the drivers of variation in plant heat tolerances and their consequences. Main types of variable contained Heat tolerance estimated in degrees Celsius from photosynthetic tissue Spatial location and grain Global in scope with undersaturated taxonomic sampling and underrepresented geographic regions. Time period and grain 1935-2024 Major taxa and level of measurement Primarily vascular plants encompassing >1700 taxa, >1000 genera and >200 families. Software format Comma-separated values

Plant phenotyping relevance

植物の熱耐性という生理形質を体系的に収集・整理したデータベースであり、方法論の不一致や変動要因も記録する再利用可能なリソースであるため、フェノタイピングデータセットとして対象に含める。
