Relationship between genome size and repeat elements in Penstemon including the relationship of both LTRs and total repeat elements to genome size for both genome reduced Penstemon and genome reduced/non-genome reduced Arabidopsis1(yellow). 1 Genome reduced A. thaliana sequence from Maughan et al. ; A. thaliana RILs Ler-0 and Col-4; Non-genome reduced A. thaliana sequence downloaded from TAIR (The Arabidopsis Information Resource) as whole chromosomes; Genome size as reported by Broderick et al. and Schmuths et al.
