Only the rbcL gene experienced efficiency of positive selection at the annual/perennial transitions. The inverted repeat (IR)/single copy (SC) boundaries were identical in all of these (Helianthus) species. In general, the comparison of the genomes revealed low levels of sequence variability (Pi = 0.00051). This indicates that the chloroplast genomes of the studied perennial species of Helianthus, in addition to purifying selection, are closely related and have a recent divergence time. Breast cancer is the most commonly diagn
