Pangenomic analysis of 31 Rhodopseudomonas strains using the exponential model. The number of gene clusters were plotted as a function of the number n of strains added sequentially. Black circles are the values obtained with the different orders in the addition of strains. The continuous red curves represent the least-squares fit of the data to an exponential function [33]. A Core genome plot. The core genome size with the addition of the 31st strain is 1,397. B Pangenome size trend. The equations are shown at the top of each plot
