与单基因分析相比，多位点序列分析在解决近缘种间亲缘关系上有更好的表现。海桑(Lythoraceae s.l.)是广泛分布于印度-西太平洋地区的红树林属植物。海桑是该属中最稀有的物种之一，但其与海桑属其他物种的亲缘关系一直存在着不一致的结果。在这项研究中，我们旨在解决OFS的系统发育地位。利用核糖体内转录间隔区(NrITS)和13个核基因的序列数据。我们首先利用nrITS和核属9重建了5个种的系统发育，这表明了这一点。Caseolaris(L.)恩格尔首先从其他物种分化而来，那就是。格里菲斯更接近于他。阿佩塔拉·布奇，-火腿还有。OvataBacker；然而，这段关系。Griffithii，S.apetala，和。卵子是无法解决的。基于nrITS和13个核基因序列的进一步系统发育分析及其应用。一个外群的案例表明了这一点。格里菲斯和S。无瓣瓣是姐妹种，有很高的自助性支持。我们得出的结论是。格里菲斯和S。无瓣带鱼有最亲密的关系。此外，我们的系统发育分析不支持以前的Sonneratia的属内分类。
Compared with single gene analysis, multi‐locus sequence data usually perform better in resolving phylogenetic relationships of closely related species.Sonneratia(Lythraceae s.l.), a genus of mangroves, is widely distributed in the Indo‐West Pacific region.Sonneratia griffithiiKurz is one of the rarest species of this genus and morphological analyses have produced conflicting results regarding its affinity to other species ofSonneratia. In this study, we aimed to resolve the phylogenetic position ofS. griffithiiby using sequence data of the nuclear ribosomal internal transcribed spacer (nrITS) and 13 nuclear genes. We first reconstructed the phylogeny of fiveSonneratiaspecies using nrITS and the nuclear generpl9, which showed thatS. caseolaris(L.) Engl. diverged first from the other species and thatS. griffithiiwas closer toS. apetalaBuch.‐Ham. andS. ovataBacker; however, the relationships amongS. griffithii,S. apetala, andS. ovatacould not be resolved. Further phylogenetic analysis based on sequences of nrITS and 13 nuclear genes and usingS. caseolarisas an outgroup showed thatS. griffithiiandS. apetalawere sister species with high bootstrap support. We conclude thatS. griffithiiandS. apetalahave the closest relationships. Furthermore, our phylogenetic analyses do not support previous intrageneric classifications ofSonneratia.
