Chloroplast simple sequence repeats amplicons in 5 subspecies of Brassica oleracea were sequenced, and one chloroplast SNP was detected in amplicon ACP43. Through the introduction of an RsaI recognition site by adding one mismatch in the forward primer, combined with the increased primer length and raised annealing temperature, the dCAPS (derived cleaved amplified polymorphic sequences) marker ACP43-93 RsaI was successfully developed. By using the dCAPS marker, the subspecies-specific SNP was assayed in 206 materials representing the wide distribution of B. oleracea. This is the first report of chloroplast DNA (cpDNA) variation in cultivated subspecies of B. oleracea, which showed that chloroplast diversity existed at the intersubspecies level. Unlike other subspecies, most of the broccoli and all of the cauliflower materials sharing the same haplotype showed closer relationships in cpDNA level. Furthermore, the dCAPS haplotype of the offspring from 7 male sterile backcross populations was the same as the female parents, indicating maternal inheritance.

is separated into four subspecies: subspecies (MAA), subspecies (MAS), subspecies (MAH), and subspecies (MAP). Understanding the mechanisms of host and tissue adaptation leading to their clinical significance is vital to reduce the economic, welfare, and public health concerns associated with diseases they may cause in humans and animals. Despite substantial phenotypic diversity, the subspecies nomenclature is controversial due to high genetic similarity.

Genomic repetitive sequences commonly show species-specific sequence type, abundance, and distribution patterns, however, their intraspecific characteristics have been poorly described. We quantified the genomic repetitive sequences and performed single nucleotide polymorphism (SNP) analysis between 29 genotypes and subspecies using publicly available raw genomic Illumina sequence reads and used fluorescence hybridization (FISH) to experimentally analyze some repeats. The majority of the identified repetitive sequences had similar contents and proportions between , , and subspecies.

, and are phenotypically and genotypically closely related, and together comprise the group. Although the strains of this group are commercially valuable as probiotics, the taxonomic status and nomenclature of the group have long been contentious because of the difficulties in identifying these three species by using the most frequently used genotypic methodology of 16S rRNA gene sequencing. Long used as the gold standard for species classification, DNA-DNA hybridization is laborious, requires expert skills, and is difficult to use routinely in laboratories.
