Fig. 3From: Genome-wide analysis of LTR-retrotransposon diversity and its impact on the evolution of the genus Helianthus (L.)PCA plots of genome proportion values for Gypsy and Copia lineages with a percentage of reads >1% in annual (black dots) and perennial (grey dots) species. The percentage of variation accounted is reported on each axis. Asterisks mark permutational MANOVA significance with the following significance codes: 0.001 ‘***’ 0.05 ‘*’Back to article page
