Abstract

Symplocarpus renifolius is a member of Araceae family that is extraordinarily diverse in appearance. Previous studies on chloroplast genomes in Araceae were focused on duckweeds (Lemnoideae) and root crops (Colocasia, commonly known as taro). Here, we determined the chloroplast genome of Symplocarpus renifolius and compared the factors, such as genes and inverted repeat (IR) junctions and performed phylogenetic analysis using other Araceae species. The chloroplast genome of S. renifolius is 158,521 bp and includes 113 genes. A comparison among the Araceae chloroplast genomes showed that infA in Lemna, Spirodela, Wolffiella, Wolffia, Dieffenbachia and Colocasia has been lost or has become a pseudogene and has only been retained in Symplocarpus. In the Araceae chloroplast DNA (cpDNA), psbZ is retained. However, psbZ duplication occurred in Wolffia species and tandem repeats were noted around the duplication regions. A comparison of the IR junction in Araceae species revealed the presence of ycf1 and rps15 in the small single copy region, whereas duckweed species contained ycf1 and rps15 in the IR region. The phylogenetic analyses of the chloroplast genomes revealed that Symplocarpus are a basal group and are sister to the other Araceae species. Consequently, infA deletion or pseudogene events in Araceae occurred after the divergence of Symplocarpus and aquatic plants (duckweeds) in Araceae and duplication events of rps15 and ycf1 occurred in the IR region.
