Abstract
The amount of plastome sequence data available has soared in the last decade, but the nature of plastome evolution during rapid radiations is largely unknown. Moreover, although there is increasing evidence showing that plastomes may have undergone adaptive evolution in order to allow adaptation to various environments, few studies have systematically investigated the role of the plastome in alpine adaptation. To address these questions, we sequenced and analyzed 12 representative species of Rhodiola, a genus which includes ca. 70 perennial herbs growing in alpine habitats in the Qinghai-Tibet Plateau and the Hengduan Mountains. Rapid radiation in this genus was triggered by the uplift of the Qinghai-Tibet Plateau. We also included nine species of Crassulaceae as the outgroups. All plastomes were conserved with respect to size, structure, and gene content and order, with few variations: each contained 134 genes, including 85 protein-coding genes, 37 tRNAs, 8 rRNAs, and 4 potential pseudogenes. Three types of repeat sequence were detected. Slight contraction and expansion of the inverted repeats were also revealed. Both the genome-wide alignment and sequence polymorphism analyses showed that the inverted repeats and coding regions were more conserved than the single-copy regions and the non-coding regions. Positive selection analyses identified three genes containing sites of positive selection (rpl16, ndhA, ndhH), and one gene with a faster than average rate of evolution (psaA). The products of these genes may be involved in the adaptation of Rhodiola to alpine environments such as low CO2 concentration and high-intensity light.
