Comparative analyses of satellitomes of the four Meloidogyne species (M.flo-M. floridensis, M.inc-M. incognita, M.jav-M. javanica and M.are-M. arenaria) based on satDNAs clustering. The grey bar plots at the top show the length of satDNA repeat unit for each satDNA cluster (MelSat). The area of the colored rectangles is proportional to the abundance of individual satDNA in a corresponding genome (ranged from 0.002 to 0.613%). Gray boxes indicate the absence of particular satDNA in a corresponding genome. Predicted level of ploidy (2n, 3n, and 4n) [28, 37] for each species is indicated. For the abundance and repeat unit length of all 83 MelSat see Additional file 1: Table S1. The consensus sequences of all 83 MelSat are listed in Additional file 1: Table S5. MelSat01 corresponds to previously described INC satDNA [31], MelSat32 corresponds to MPA2 [11] and MelSat60, MelSat65, and MelSat76 represent previously published MARJA, MPA1, and AJL satDNAs respectively [12, 38, 39]
