Figure 2

Microsatellite-based genetic structure of common sage (Salvia officinalis L.) derived from Bayesian model-based clustering analysis using STRUCTURE. (a) Population structure assuming K = 2 and (b) K = 5. Each colour represents one genetic cluster: light blue—SAp, dark blue—CAp, yellow—NBalk, red—CBalk, and green—SBalk. The satellite imagery was obtained from Natural Earth public domain map dataset (https://www.naturalearthdata.com/downloads/10m-raster-data/10m-gray-earth/). CorelDraw Graphics Suite X7 Version 17.1.0.572 (Corel Corp., Ottawa, Canada) was used to create the figure.
