Complete Chloroplast Genome Sequence and Comparative and Phylogenetic Analyses of the Cultivated Cyperus esculentus

Cyperus esculentus produces large amounts of oil as one the main storage reserves in underground tubers, making this crop species not only a promising resource for edible and biofuel food chemical industry, but also model system studying accumulation non-seed tissues. In study, we determined chloroplast genome sequence cultivated C. (var. sativus Boeckeler). The results showed that complete was 186,255 bp size, possessed typical quadripartite structure containing single copy (100,940 bp) region, small (10,439 pair inverted repeat regions 37,438 size. Sequence analyses indicated encodes 141 genes, including 93 protein-coding 40 transfer RNA 8 ribosomal genes. We identified 396 simple-sequence repeats 49 long repeats, 15 forward 34 palindromes within esculentus. Most these were distributed noncoding regions. Whole comparison with those other four both more divergent than highest variation found phylogenetic trees based on genomes 13 species, all five Cyperaceae formed clade, evolutionarily related to rotundus three species. summary, provides valuable genomic identification, evolution, comparative research family.
