Genome-wide presence and absence variation (PAV) analysis between the cultivated pineapple A. comosus var. F153 and its wild relative A. comosus var. bracteatus CB5, and among 86 Ananas accessions. A Proportion of present (green) and absent (orange) ml-MITEs and mt-MITEs between F153 and CB5 genomes. B Proportion of present ml-MITEs (red) and mt-MITEs (blue) among the 86 Ananas accessions. C The 86 Ananas accessions were divided into six groups based on population structure analysis. Proportions of the present ml-MITEs (red) and mt-MITEs (blue) are displayed. D An example shows variations of Ac-mMITE clusters between F153 and CB5 genomes. The coordinates of the Ac-mMITE cluster in F153 and CB5 genomes are labeled above and below of the schematics, respectively
