The chloroplast genome sequences of Ipomoea alba and I. obscura (Convolvulaceae): genome comparison and phylogenetic analysis.

ABSTRACT: Ipomoea species have diverse uses as ornamentals, food, and medicine. However, their genomic information is limited; I. alba and I. obscura were sequenced and assembled. Their chloroplast genomes were 161,353 bp and 159,691 bp, respectively. Both genomes exhibited a quadripartite structure, consisting of a pair of inverted repeat (IR) regions, which are separated by the large single-copy (LSC) and small single-copy (SSC) regions. The overall GC content was 37.5% for both genomes. A total of 104 and 93 simple sequence repeats, 50 large repeats, and 30 and 22 short tandem repeats were identified in the two chloroplast genomes, respectively. G and T were more preferred than C and A at the third base position based on the Parity Rule 2 plot analysis, and the neutrality plot revealed correlatio
