Abstract
Genus Prosopis (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 Prosopis species (P. juliflora and P. cineraria) and compared them with previously sequenced P. glandulosa, Adenanthera microsperma, and Parkia javanica belonging to the same family. The complete genome sequences of Prosopis species and related species ranged from 159,389 bp (A. microsperma) to 163,677 bp (P. cineraria). The overall GC contents of the genomes were almost the similar (35.9–36.6%). The P. juliflora and P. cineraria 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 P. juliflora, P. cineraria and P. glandulosa cp genomes, respectively. Similarly, the maximum number of simple sequence repeats were determined in P. juliflora (88), P. cineraria (84), and P. glandulosa (78). Moreover, complete cp genome comparison determined a high degree of sequence similarity among P. juliflora, P. cineraria, and P. glandulosa, however some divergence in the intergenic spacers of A. microsperma and Parkia javanica were observed. The phylogenetic analysis showed that P. juliflora is closer to P. cineraria than P. glandulosa.
Highlights
The Prosopis L. genus belongs to the Leguminosae (Fabaceae) family, sub-family Mimosoideae
The sizes of the P. juliflora and P. cineraria cp genomes are 163,237 and 163,677 bp, respectively (Figure 1 and Table 1). Both P. juliflora and P. cineraria cp genomes were analyzed and compared with three associated cp genomes, with sizes ranging from 159,389 bp (A. microsperma) to 163,677 bp (P. cineraria) (Table 1)
The genomics characteristics genome size, GC contents, genome organization and gene orders were found to be highly conserved as compared to related cp genomes
Summary
The Prosopis L. genus belongs to the Leguminosae (Fabaceae) family, sub-family Mimosoideae. Prosopis genus can be found around the world in arid and semi-arid regions, including Central and North Africa, South and North America, and the Caribbean region. It has both economic and ecological reputation in arid regions [1,2] and is related with chaquenian areas in Brazil [3]. Prosopis taxa grow in most of the world’s warm arid and semi-arid areas, both as introduced and native species [6] They have been introduced universally and have become naturalized or invasive in various part of the world [7]
