taken from each subfamily of core Asteraceae. The trnT-GGU gene of Barnadesia lehmannii is labeled to show the functional parts as representative of all species. The perfect clover leaf structure of trnT-GGU exists in the species of nine subfamilies, including Barnadesioideae, Famatinanthoideae, Stifftioideae, Mutisioideae, Gochnatioideae, Wunderlichioideae, Hecastocleidoideae, Pertyoideae, and Carduoideae. The B. lehmannii represent the structure of trnT-GGU of the species of all nine subfamilies. The insertion occurred in the species of four subfamilies of core Asteraceae (Gymnarrhenoideae, Cichorioideae, Corymbioideae, and Asteroideae), which also correspond to mismatches above the anticodon loop. The insertion is highlighted with a box.
