Chloroplast-to-nuclear transfer hotspots in chloroplast genomes of four cotton species. LSC: large single copy region. IR: inverted repeat region. SSC: Small single copy region. Four cotton species are shown in different shades of gray. The frequency of chloroplast-to-nuclear transfers is along the vertical axis. The bars represent the frequency of sequences transferring from the chloroplast to the nucleus of four cotton species. The error bars represent +/− 5%
