Data for supermatrix phylogeny of the Senecioneae

DNA sequence data alignments, partitioning information and resulting phylogenetic trees for study of evolutionary relationships of the groundsel tribe (Senecioneae) of the daisy family (Asteraceae).\nLineage: Most sequence data were obtained from Genbank. Additional ETS psbA-trnH, and trnL-trnF sequences were produced for 32 previously unexamined native Australian species using Sanger sequencing. Alignments were produced using MAFFT 7.310 under automatic algorithm selection and subsequently examined, manually corrected and cropped in AliView 1.22. Phylogenetic trees were inferred using IQ-TREE 1.4.4 under automatic partition finding using sequence regions as starting partitions, automatic model selection for each partition, and with 1,000 UltraFast Bootstrap samples as branch support.

本数据集涵盖用于研究菊科（Asteraceae）千里光族（Senecioneae）演化关系的DNA序列比对数据、分区信息及最终构建的系统发育树。
数据获取与处理：大部分序列数据源自GenBank（基因库）。针对32个此前未被研究的澳大利亚本土物种，本研究通过桑格测序（Sanger sequencing）获取了额外的ETS、psbA-trnH及trnL-trnF序列。序列比对通过MAFFT 7.310完成，采用自动算法选择策略；随后使用AliView 1.22对比对结果进行检视、手动校正与序列裁剪。系统发育树的推断采用IQ-TREE 1.4.4实现，以序列区域作为初始分区开展自动分区识别，为每个分区自动选择最优进化模型，并通过1000次超快速自举（UltraFast Bootstrap）抽样计算分支支持度。
