Complete Mitochondrial Genome Sequences of Korean Phytophthora infestans Isolates and Comparative Analysis of Mitochondrial Haplotypes.

Potato late blight caused by Phytophthora infestans is a destructive disease in Korea. To elucidate the genomic variation of the mitochondrial (mt) genome, we assembled its complete mt genome and compared its sequence among different haplotypes. The mt genome sequences of four Korean P.

Analysis of genetic diversity and population structure among cultivated potato clones from Korea and global breeding programs.

Characterizing the genetic diversity and population structure of breeding materials is essential for breeding to improve crop plants. The potato is an important non-cereal food crop worldwide, but breeding potatoes remains challenging owing to their auto-tetraploidy and highly heterozygous genome. We evaluated the genetic structure of a 110-line Korean potato germplasm using the SolCAP 8303 single nucleotide polymorphism (SNP) Infinium array and compared it with potato clones from other countries to understand the genetic landscape of cultivated potatoes.

Mitochondrial genome recombination in somatic hybrids of Solanum commersonii and S. tuberosum.

Interspecific somatic hybridization has been performed in potato breeding experiments to increase plant resistance against biotic and abiotic stress conditions. We analyzed the mitochondrial and plastid genomes and 45S nuclear ribosomal DNA (45S rDNA) for the cultivated potato (S. tuberosum, St), wild potato (S.

Distribution of Species Isolated in South Korea and Comparison of Temperature Effects on Pathogenicity.

, which causes soft rot disease, is divided into 18 species based on the current classification. A total of 225 strains were isolated from 10 main cultivation regions of potato (), napa cabbage ( subsp. ), and radish () in South Korea; 202 isolates (90%) were from potato, 18 from napa cabbage, and five from radish.

The complete chloroplast genome sequence of , one of the potato wild relative species.

is a wild tuber-bearing species belonging to the family Solanaceae. The complete chloroplast genome of was constituted by assembly, using a small amount of whole genome sequencing data. The chloroplast genome of was a circular DNA molecule with a length of 155,549 bp and consisted of 85,990 bp of large single copy, 18,373 bp of small single copy, and 25,593 bp of a pair of inverted repeat regions.

Mitochondrial genome sequence of tuber-bearing wild potato, Dunal.

We report two complete mitochondrial genome sequences of a tuber-bearing wild potato species (). The genomes are circular DNA molecules with lengths of 213,676 bp and 338,427 bp containing 80 nonredundant genes totally, including 34 protein-coding genes, 25 hypothetical open reading frames, 18 tRNA genes, and 3 rRNA genes. Phylogenetic analysis using common protein-coding sequences confirmed that belongs to the Solanoideae subfamily in the Solanaceae family.

Chloroplast genome of the wild tuber-bearing diploid potato relative .

is a wild tuber-bearing species belonging to Solanaceae family. The chloroplast genome of the species was completed by assembly using a small amount of whole genome sequencing data. The genome is the circular DNA molecule with a length of 155,532 bp containing 159 predicted genes totally, including 105 protein-coding, 45 tRNA and eight rRNA genes.

The complete mitochondrial genome sequences of potato ( L., Solanaceae).

Potato () from the Solanaceae is the fourth most important food crop worldwide. In this study, five complete mitochondrial genome sequences of were characterized through assembly of whole genome sequencing data. The resulting circular mitochondrial DNA molecules ranged from 49,171 bp to 297,014 bp in size and contained a total of 80 non-redundant genes, comprising 34 protein-coding genes, 24 hypothetical open reading frames, 19 tRNA genes, and 3 rRNA genes.
