| Summary: | Genus <i>Prosopis</i> (family Fabaceae) are shrubby trees, native to arid and semi-arid regions of Asia, Africa, and America and known for nitrogen fixation. Here, we have sequenced the complete chloroplast (cp) genomes of two <i>Prosopis</i> species (<i>P</i>. <i>juliflora</i> and <i>P</i>. <i>cineraria</i>) and compared them with previously sequenced <i>P. glandulosa</i>, <i>Adenanthera microsperma</i>, and <i>Parkia javanica</i> belonging to the same family. The complete genome sequences of <i>Prosopis</i> species and related species ranged from 159,389 bp (<i>A</i>. <i>microsperma</i>) to 163,677 bp (<i>P</i>. <i>cineraria</i>). The overall GC contents of the genomes were almost the similar (35.9–36.6%). The <i>P. juliflora</i> and <i>P. cineraria</i> genomes encoded 132 and 131 genes, respectively, whereas both the species comprised of 85 protein-coding genes higher than other compared species. About 140, 134, and 129 repeats were identified in <i>P</i>. <i>juliflora</i>, <i>P</i>. <i>cineraria</i> and <i>P</i>. <i>glandulosa</i> cp genomes, respectively. Similarly, the maximum number of simple sequence repeats were determined in <i>P</i>. <i>juliflora</i> (88), <i>P</i>. <i>cineraria</i> (84), and <i>P. glandulosa</i> (78). Moreover, complete cp genome comparison determined a high degree of sequence similarity among <i>P</i>. <i>juliflora</i>, <i>P. cineraria,</i> and <i>P. glandulosa,</i> however some divergence in the intergenic spacers of <i>A. microsperma</i> and <i>Parkia javanica</i> were observed. The phylogenetic analysis showed that <i>P</i>. <i>juliflora</i> is closer to <i>P</i>. <i>cineraria</i> than <i>P. glandulosa</i>. |
