Inheritance of Solanum chloroplast genomic DNA in interspecific hybrids

Abstract

The chloroplast genomic information was obtained from three wild Solanum and four hybrids by chloroplast genome sequencing. The chloroplast genomes of the seven samples comprise of a circular structure and sizes from 155,581 to 155,612 bp and composed of 130 genes. The genome structures of the two hybrids were identical, while the other two hybrids showed 2 bp differences in the LSC when compared with their maternal parent. The total sites of SNP and InDel were 39–344 and 54–90, respectively. With the exception of one hybrid with two additional sites, the other hybrids were identical to their maternal.
