Figure 1

Core components involved in small RNAs biogenesis. (a–c) Phylogenetic tree based on the alignment of protein sequences of DCLs, RDRs and HEN1 from eleven plant species. (d) Schematic representation of the conserved domains in plant DCLs, RDRs and HEN1. The proteins that haven’t been accurately identified are marked with “predicted” after their names. Protein sequences were aligned using MEGA X (https://www.megasoftware.net/) (5 October 2021) to perform the phylogenetic tree. The analysis of the conserved domains was based on TBtools (https://www.yuque.com/cjchen/hirv8i) (5 October 2021). Additional abbreviations: DUF283, domain of unknown function 283; PAZ, PIWI/ARGONAUTE/ZWILLE; LCD, La-motif-containing domain; PLD, PPIase-like Domain. Species names are abbreviated as follows: Sl, Solanum lycopersicum; Nt, Nicotiana tabacum; At, Arabidopsis thaliana; Ca, Capsicum annuum; Sb, Sorghum bicolor; Hv, Hordeum vulgare; Cs, Cucumis sativa; Zm, Zea mays; Os, Oryza sativa; St, Solanum tuberosum; Vv, Vitis vinifera.
