Characterization of the complete chloroplast genome of endangered Cycads Zamia fischeri Miq. ex Lem

The whole chloroplast (cp) genome sequence of Zamia fischeri has been characterized. The cp genome length was 164,767bp in length, with a GC content of 39.7%, containing a large single copy (LSC) of 90,226bp, a small single copy (SSC) of 23,223bp, and a pair of inverted repeats (IRs) of 25,659bp. The genome contained 127 genes, including 88 protein-coding genes, 31 tRNA genes, and 8 rRNA genes. A phylogenetic analysis based on complete chloroplast genomes in Cycads indicates that Z. fischeri clustered with another Zamia (Z. furfuracea). This complete chloroplast sequence offers a promising tool for further species identification, population genetic conservation, and evolutionary studies of Zamiaceae, as well as for Cycadales.
