Characterization of the complete chloroplast genome of a Peruvian landrace of Capsicum chinense Jacq. (Solanaceae), arnaucho chili pepper.

Peru harbors the largest morphological diversity of cultivated chili peppers worldwide (Meckelmann et al., 2013), and they play a crucial role in the Peruvian cuisine and cultural traditions (Morales-Soriano et al., 2018). Arnaucho chili pepper is a landrace cultivated by small farmers in a restricted area named “Valle de Supe” (around 200 km northern Lima) and is an important representative in the gastronomy of Lima region. Even though NGS techniques are being employed to study Capsicum spp. genomes, very little is known about the Peruvian chili pepper landraces genome characterization. In addition, knowledge about Peruvian C. chinense phylogenetic relationships is scarce. In this study, we sequenced the first complete chloroplast (cp) genome of a Peruvian chili pepper landrace, “arnacucho” (Capsicum chinense). This cp genome has a 156,931 bp in length with typical quadripartite structure, containing a large single copy (LSC ) region (87,325 bp) and an 17,912 bp small single-copy (SSC) region, separated by two inverted repeat (IR) regions (25,847 bp); and the percentage of GC content was 37.71%. Arnaucho chili pepper chloroplast genome possesses 133 genes that consists of 86 protein-coding genes, 37 tRNA, eight rRNA, and two pseudogenes. Phylogenetic analysis revealed that this Peruvian chili pepper landrace is closely related to the undomesticated species C. galapagoense; all belong to the Capsiceae tribe. Apparently, this landrace represents another member of the Capsicum complex. Further research is needed considering a wider sampling representation.
