Abstract
The entire chloroplast and mitochondrial genomes of domesticated and wild type sunflower were sequenced. The comparative analysis of chloroplast genomes revealed 43 variant sites, including 21 polymorphic SSR loci and 22 SNPs. About 14 variant sites were found by collation of mitochondrial DNA (mtDNA), among them 4 SSRs, 8 SNPs and 2 deletions. About 9 SNPs were located in coding region of chloroplast DNA (cpDNA) and single SNP was mapped in mitochondrial gene. Only three SNPs caused amino acid changes: Two SNPs in cpDNA and one mtDNA SNP. Despite the fact that sunflower mitochondrial genome sequence is twice as long as chloroplast genome sequence, mtDNA has one third as much variant sites than cpDNA.
