The transcriptome of Utricularia vulgaris, a rootless plant with minimalist genome, reveals extreme alternative splicing and only moderate sequence similarity with Utricularia gibba.

ABSTRACT:

Background

The species of Utricularia attract attention not only owing to their carnivorous lifestyle, but also due to an elevated substitution rate and a dynamic evolution of genome size leading to its dramatic reduction. To better understand the evolutionary dynamics of genome size and content as well as the great physiological plasticity in this mostly aquatic carnivorous genus, we analyzed the transcriptome of Utricularia vulgaris, a temperate species with well characterized physiology and ecology. We compared its transcriptome, namely gene content and overall transcript profile, with a previously described transcriptome of Utricularia gibba, a congener possessing one of the smallest angiosperm genomes.

Results

We sequenced a normalized cDNA library prepared from total R
