  • By using a marker-assisted approach, it will provide a noninvasive road map to expedite the selective introgression of useful traits in the years ahead.

  • Shared mutations suggest that introgression took place after mutational separation had occurred, leading to the introduction of groups of mutations by genetic recombination.

  • Tridentatae , we previously concluded [ 34 35 ] that S. bigelowii was perhaps misplaced and should be excluded from the Tridentatae . In addition, we explained [ 34 35 ] an unexpected relationship between it and A. filfifolia as possible hybridization and introgression involving bidirectional gene flow rather than recent common ancestry because heterogamous-disciform A. bigelowii differs from heterogamous-disciform A. filifolia by perfect disk florets instead of female-sterile disk florets.

  • Potential limitations of using mtDNA to infer species boundaries include retention of ancestral polymorphism, male-biased gene flow, selection on any mtDNA nucleotide (as the whole genome is one linkage group), introgression following hybridization, and paralogy resulting from transfer of mtDNA gene copies to the nucleus.

  • The occasional appearance of disciform capitula in S. bigelowii might be explained by introgression of genes or alleles from A. filfolia that control ray expression, a phenomenon observed in discoid Senecio squallidus and radiate S. vulgaris in Europe [ 67 ] . While this is speculative, it is consistent with hypotheses that hybridization and introgression are widespread in sect.
