Phylogenetic and sequence analysis of GhYGL1d and its expression pattern. a Computational prediction for identification of leaf-related RNA editing factors in cotton. b Schematic structures of GhYGL1d proteins. Predicted targeting peptide, P, E, E+ and DYW domains are labeled on the protein sequence. The targeting peptide was predicted using the TargetP software (www.cbs.dtu.dk/services/TargetP/). The PPR motifs and domains were predicted by TPRpred software (https://toolkit.tuebingen. mpg.de/#/tools/tprpred). c Phylogenetic tree analysis of GhYGL1d proteins in plants were performed using the MEGA program (www.megasoftware.net). The phylogenetic tree was generated by MEGA5.0. d YGL1 protein in Gossypium raimondii (XP_012456442), Gossypium arboreum (XP_017631921), Theobroma cacao (XP_017979491.1), Arabidopsis thaliana (NP_173004.1), Vitis vinifera (XP_002285225.2), Glycine max (XP_003529817.2), Oryza sativa (XP_015639788.1), Zea mays (XP_008650050.1), Sorghum bicolor (XP_002440297.2), Physcomitrella patens (XP_001780298.1), Selaginella moellendorffii (XP_002964227.1), Ostreococcus tauri (XP_003078586.1), and Chlorella variabilis (XP_005844014.1) were selected to generate a bootstrap neighbor–joining phylogenetic unrooted tree. The numbers at each node represent the bootstrap values (%) calculated from 1,000 trials. The length of branches indicates the extent of divergence according to the bar scale (relative units) at the bottom.
