Comparative Transcriptome Analysis Reveals Adaptive Evolution of Notopterygium incisum and Notopterygium franchetii, Two High-Alpine Herbal Species Endemic to China.

ABSTRACT: The extreme conditions (e.g., cold, low oxygen, and strong ultraviolet radiation) of the high mountains provide an ideal natural laboratory for studies on speciation and the adaptive evolution of organisms. Up to now, few genome/transcriptome-based studies have been carried out on how plants adapt to conditions at extremely high altitudes. Notopterygium incisum and Notopterygium franchetii (Notopterygium, Apiaceae) are two endangered high-alpine herbal plants endemic to China. To explore the molecular genetic mechanisms of adaptation to high altitudes, we performed high-throughput RNA sequencing (RNA-seq) to characterize the transcriptomes of the two species. In total, more than 130 million sequence reads, 81,446 and 63,153 unigenes with total lengths of 86,924,837 and
