Abstract
The complete chloroplast genomes from two salt cresses (Eutrema halophilum and Eutrema botschantzevii), plants known to tolerate high levels of salt, are determined in this study. The genome sizes were 153,312 and 153,280 bp. Both genomes containing a large single copy region (LSC) of 84k bp and a small single copy region (SSC) of 18k bp, which were separated by a pair of 25,928 bp inverted repeat regions (IRs). The cpDNA contained 125 genes, including 87 protein-coding genes (79 PCG species), 30 tRNA genes (25 tRNA species) and eight ribosomal RNA genes (4 rRNA species). The most of gene species occur as a single copy, while 17 gene species occur in double copies. These complete chloroplast genomes can be subsequently used for population studies of Eutrema, and provide valuable insight into conservation and restoration efforts for this endangered species.
