A dissected-leaved form of Ranunculus repens L. occurs in the temporary limestone lakes (turloughs) across the west of Ireland. Turloughs fill with groundwater for up to 8 months of the year. Under experimental conditions, these turlough populations demonstrated a higher rate of aerial and submerged photosynthesis than populations of the more typical broad-leaved ruderal form. The turlough popu...

Dioscorea opposita Thunb., included in the genus Dioscorea of the family Dioscoreaceae, is an important herb with great edible and medicinal value. In this study, the total RNA from leaves of Lichuan Dioscorea opposita Thunb. was isolated by an improved Trizol method. The results showed that the RNA extracted by the improved Trizol method had good integrity, and the RNA could be used for down-s...

Anemone coronaria L. and Ranunculus asiaticus L. both belong to the Ranunculaceae, a large plant family with many ornamentals of horticultural importance. There are considerable differences between these species leaves, flower morphology and flower colour therefore intergeneric crosses between the species might result in new interesting hybrids. Crosses between Anemone coronaria L. and Ranuncul...

Ranunculus glacialis ssp. glacialis is an arctic-alpine plant growing in central and southern European and Scandinavian mountain ranges and the European Arctic. In order to elucidate the taxon's migration history, we applied amplified fragment length polymorphism (AFLP) to populations from the Pyrenees, Tatra mountains and Northern Europe and included data from a previous study on Alpine access...
