摘要

运用克隆测序的方法测定了椴树科Tiliaceae、梧桐科Sterculiaceae、杜英科Elaeocarpaceae和大风子科Flacourtiaceae 21种以及外类群蔷薇科4种植物的叶绿体

trn

L-

trn

F序列，并结合GenBank中已公布的3科44个代表种的

trn

L-

trn

F序列进行系统发育分析。采用最简约法、最大似然法和Bayesian推测分析椴树科、梧桐科和杜英科科间和属内的系统发育关系。结果显示：①文定果属

Muntingia

构成一个独立于梧桐科和椴树科的分支，具有较高bootstrap的支持率和后验概率，表明建立文定果科Muntingiaceae具有合理性；②滇桐属

Craigia

与梧桐科翅子树属

Pterospermum

、肖槿属

Thespesia

、苹婆属

Sterculia

、可乐果属

Cola

、梧桐属

Firmiana

和银叶树属

Heritiera

的关系密切。支持将滇桐属归于梧桐科的观点；③杜英属

Elaeocarpus

和猴欢喜属

Sloanea

均为杜英科的主要成员，应归于杜英科；④椴树科、梧桐科和杜英科有较近的亲缘关系。特别是，椴树科和梧桐科的关系非常密切，两科并没有构成两个独立的单系群，而是形成复系群。

Abstract

The chloroplast

trn

L-

trn

F sequences of 21 species in Tiliaceae

Sterculiaceae and Elaeocarpaceae and 4 species in Rosaceae were determined by sequencing cloned PCR products. In this study

the phylogeny was inferred using dataset of chloroplast

trn

L-

trn

including 44 sequences from GenBank. The results from Bayesian inference

maximum parsimony

and maximum likelihood consistently showed that：①

Muntingia calabura

formed an independent clade with high support values

which the foundation on Muntingiaceae was rational; ②

Craigia

closed to the genera

Pterospermum

Thespesia

Sterculia

Cola

Firmiana

and

Heritiera

should be placed in Sterculiaceae; ③

Elaeocarpus

and

Sloanea

were two valid genera in Elaeocarpaceae; ④ Tiliaceae and Sterculiaceae doesn't consist of two independent clades

but those are existed to be a close relationship among three families included Elaeocarpaceae.
