英文摘要 | The subfamily thalictroideae, which is cle,[rly defined by its chromosome characters, contains nine or ten 2enera. here,,ve use sequences of chloroplast rbcl and niatk genes as well as non-coding irnl-f and nuclear its regions to reconstruct the generic level phylogeny of this subfamily. our data recognize three major groups within thalictroideae: (1) thalictrvin, lcptopyruni, paropyrurn, and paraquilegia; (2) urophysa, seiniaquilegia, and aquilegia; and (3) dichocurpum, enetnion, and isopyruni. isopyruni anemonoides, the sole species of paropyrinn, and paraquilegia form a clade sister to leptopyruni; together they make up the first group. isopyrian inanshurician and 1. thalictroides form another clade within the third group. isopyrum anel?70170ides is sister to the monophyletic faraquilegia. our data suggest that isopyrtan is polyphyletic and support the segregate genus poropyrian. reconstruction of petal evolution suggests a secondary loss of petals in eneinion and thalictrian, in contrast with the view that apetalous taxa, are the most primitive. petals with lonlyer stalks in dichocarpinn are shown to be derivative, refuting the viewpoint that this type is a primitive condition. the flat petals in poraquilegia may be derived from the tubular-type petals in paropyrum and leptopyrion, and spurred petals are thought to have originated from a single ancestor. |
