Genetic History of the Remnant Population of the Rare Orchid Cypripedium calceolus Based on Plastid and Nuclear rDNA.

ABSTRACT: The lady's slipper orchid (Cypripedium calceolus), which inhabits shady deciduous and mixed forests and meadows, is now threatened with extinction in many European countries, and its natural populations have been dramatically declining in recent years. Knowledge of its evolutionary history, genetic variability, and processes in small populations are therefore crucial for the species' protection. Nowadays, in south-west Poland, it is only distributed in seven small remnant and isolated populations, which we examined. One nuclear (ITS rDNA) and two plastid (accD-psa1, trnL-F) markers were analyzed and compared globally in this study. Based on the nuclear marker, the most common ancestor of C. calceolus and Cypripedium shanxiense existed about 2 million year
