A. Principal component analysis of phenotype under different conditions. For source data '2022_DeChiara_Nature_Ecology_&_Evolution' strains with >50% missing values were filtered. Then the missing values were imputed by KNN. The PCA was based on the subset (the specific strain collection) of the imputed data. For source data '2018_Peter_Nature' there are no missing values. So all strains are reserved.
