Mitogenomic Research of Silverleaf Sunflower (<i>Helianthus argophyllus</i>) and Its Interspecific Hybrids

Interspecific hybridization is widespread for sunflowers, both in wild populations and commercial breeding. One of the most common species that can efficiently cross with <i>Helianthus annuus</i> is the Silverleaf sunflower—<i>Helianthus argophyllus</i>. The current study car...

description Interspecific hybridization is widespread for sunflowers, both in wild populations and commercial breeding. One of the most common species that can efficiently cross with <i>Helianthus annuus</i> is the Silverleaf sunflower—<i>Helianthus argophyllus</i>. The current study carried out structural and functional organization analyses of mitochondrial DNA in <i>H. argophyllus</i> and the interspecific hybrid, <i>H. annuus</i> (VIR114A line) × <i>H. argophyllus</i>. The complete mitogenome of <i>H. argophyllus</i> counts 300,843 bp, has a similar organization to the mitogenome of cultivated sunflower, and holds SNPs typical for wild sunflowers. RNA editing analysis predicted 484 sites in <i>H. argophyllus</i> mitochondrial CDS. The mitochondrial genome of the <i>H. annuus</i> × <i>H. argophyllus</i> hybrid is identical to the maternal line (VIR114A). We expected that significant rearrangements in the mitochondrial DNA of the hybrid would occur, due to the frequent recombination. However, the hybrid mitogenome lacks rearrangements, presumably due to the preservation of nuclear–cytoplasmic interaction paths.
