Abstract: | Not only are transposable elements profuse in the bacterial endosymbiont of maize weevils, but we found that their quantities also vary ~10-fold among individual weevils. Because multicopy elements can facilitate homologous recombination, this insertion sequence (IS) load variability suggests that these essentially asexual bacteria may exhibit substantial intraspecific genomic variation. |
