Despite the strength of climatic variability at high latitudes and upper elevations, we still do not fully understand how plants in North America that are distributed between Arctic and alpine areas responded to the environmental changes of the Quaternary. To address this question, we set out to resolve the evolutionary history of the King's Crown, Rhodiola integrifolia using multi-locus popula...

d-Isocitric acid’ has, in recent years, attracted much interest as one of the organic acids concerned in reactions catalyzed by the enzymes of various animal and plant tissues. A demand has accordingly arisen for specimens of this rare substance for use in investigations of the enzyme systems involved. The fortunate observation that d-isocitric acid is present in the leaves of succulent plants ...

The evolution and current distribution of the Sino-Tibetan flora have been greatly affected by historical geological events, such as the uplift of the Qinghai-Tibetan Plateau (QTP), and Quaternary climatic oscillations. Rhodiola kirilowii, a perennial herb with its distribution ranging from the southeastern QTP and the Hengduan Mountains (HM) to adjacent northern China and central Asia, provide...
