From: Pangenome analysis reveals transposon-driven genome evolution in cotton
LTR retrotransposon dynamics after polyploidization. a TE components in diploid and tetraploid cotton. b Comparison of LTR retrotransposon abundance in a different cluster. “A2” only has members in the A2 genome. “At_Dt” represents only the tetraploid genome, and “common” has members in all four genomes. c Amplification time of different classification clusters. d The LTR retrotransposon retention rate in four genomes. The X-axis indicates the CV (coefficient of variation) threshold of the truncated LTR length in four genomes, and the right indicates the LTR retention length with high variability in the homologous regions. e, f Linear regression analysis of insertion distances and insertion times for Gypsy and Copia
