图2. 基于8个叶绿体DNA序列片段及4个时间键准点采用BEAST分析所得广义苋科分化时间
黑色圆点表示时间键准点所在位置。空心箭头示广义苋科冠群节点。Ach: 牛膝亚科; Aer: 白花苋亚科; Ama: 苋亚科; Bet: 甜菜亚科; Cam: 樟味藜亚科; Cel: 青葙亚科; Che: 藜亚科; Cor: 虫实亚科; Gom: 千日红亚科; Pol: 多节草亚科; Sali: 盐角草亚科; Sals: 猪毛菜亚科; Sua: 碱蓬亚科
Figure 2. Chronogram based on the BEAST analysis of the combined matrix of eight plastid DNA regions and four calibrations
Calibration points are depicted with black circles. The crown node of Amaranthaceae sensu lato is shown by a hollow arrowhead. Ach: Achyranthoideae; Aer: Aervoideae; Ama: Amaranthoideae; Bet: Betoideae; Cam: Camphorosmoideae; Cel: Celosioideae; Che: Chenopodioideae; Cor: Corispermoideae; Gom: Gomphrenoideae; Pol: Polycnemoideae; Sali: Salicornioideae; Sals: Salsoloideae; Sua: Suaedoideae
