“…Aligned regions were concatenated into whole plastomes using the script concat_plastomes.pl (https:// github.com/mrmckain/Chloroplast-Phylogenomics-Utilities). Arundinelleae, represented here by Garnotia Brongn., was selected as the outgroup for the ML reconstruction and BI, based on previous morphological and molecular data (Clayton and Renvoize 1986;Kellogg 2000;Teerawatananon et al 2011;Soreng et al 2015;Veldkamp et al 2015). ML analysis was performed on the concatenated sequences under the General Time Reversible (GTR) model with the proportion of invariant sites and a gammashaped distribution of rates across sites (GTR 1 G 1 I) in RAxML v8.2.4 (Stamatakis 2006) with 1,000 bootstraps.…”
