Table 3. Data partition characteristics, summary statistics and models of the phylogenetic analyses
: Explanation note: For each data partition (ITS, ETS, trnT-trnL-trnF, rpoB-trnC, MatK) and concatenated dataset (plastid and nuclear), the following are given: number of sequences, number of characters, number of parsimony informative (PI) characters, % parsimony informative characters, maximum parsimony tree length (L), number of most parsimonious trees, consistency index excluding uninformative characters (CI) and retention index (RI). Also given are the models used in the Bayesian analyses as determined using the Akaike information criterion (AIC) in jModeltest.

表3 系统发育分析的数据分区特征、汇总统计量与分析模型
说明：针对各数据分区（ITS、ETS、trnT-trnL-trnF、rpoB-trnC、MatK）以及合并数据集（质体组与核基因组），均提供以下信息：序列数、特征位点数、简约信息（parsimony informative, PI）位点数、简约信息位点占比、最大简约树树长（L）、最简约树总数、剔除非信息位点后的一致性指数（consistency index, CI）以及保留指数（retention index, RI）。此外，还提供了通过jModeltest软件基于赤池信息准则（Akaike information criterion, AIC）筛选得到的贝叶斯分析所用模型。
