B chromosomes are supernumerary chromosomes found in numerous plant species, including in the genus Lilium. Lilium amabile, an endemic Korean Lilium species, carries B chromosomes which are highly variable in terms of numbers and shape among the accessions collected throughout the Korea. Class 1 retrotransposons are highly abundant in the genome of Lilium species, but their biological functions are still obscure. Lilium species were known to hold high diversities derived from retrotransposons.
