bladderwort

(blăd`ərwûrt', –wôrt'), any plant of the genus Utricularia, insectivorous or carnivorous aquatic plants, many native to North America. Small animals are caught and digested in bladderlike organs of the finely divided submerged leaves. Bladderworts and similar related genera are an important element of aquatic and marsh flora on all continents. They are sometimes grown in aquariums as curiosities. Bladderworts are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

That is, at three distinct times in the course of its evolution, the bladderwort's genome doubled in size, with offspring receiving two full copies of the species' entire genome.
The scientists said that it seems that the plant has been busy deleting noncoding "junk" DNA from its genetic material over many generations, which may explain differences between bladderworts and junk-heavy species like corn and tobacco - and humans.

To test this hypothesis, I aim to develop a model system for carnivorous plants based on Utricularia gibba (humped bladderwort), which has the advantage of having one of the smallest genomes known in plants (~2/3 the size of the Arabidopsis genome) and small transparent pitcher-shaped leaves amenable to imaging.
