Ported by larger bootstrap values (!60). This neighbour joining tree is additional supported by a maximum likelihood tree (Supplementary Fig. S4). The variations amongst these two trees are primarily on subgroups Ia and IIc. In the domain tree, the WRKY domains of your subgroup Ia OnWRKY4 have been clustered inside the IaN and IaC clades, respectively. In the complete protein sequence domain tree, OnWRKY4, was found in the IIc3 clade. Also, inside the domain tree, among the 22 group IIc proteins, OnWRKY53.two and 0 had been found within the IaC clade, and OnWRKY57 and 06 inside the IaN clade (Fig. 7). Inside the full proteinH.

The diversification on the WRKY genes into four groups resulted from a lengthy evolution history. Quite a few hypotheses have already been proposed to clarify how WRKY genes evolved. Hypothesis 1 stated that subgroup Ia was the ancestor of other WRKY genes.two,32,42,48 Hypothesis two proposed that subgroup Ia and IIc possess a common ancestor, IIc-like genes, and also other WRKY group genes evolved from subgroup Ia.48 Hypothesis 3 gave two option possibilities for the evolution of WRKY genes–the “Group I Hypothesis” recommended that group Ia WRKY genes would be the most primitive and all other WRKY genes are derived in the C-terminal domain on the group Ia WRKY genes; the “IIa b Separate Hypothesis” stated that groupIIa b WRKY genes evolved straight from the single WRKY domain with the ancestral algae WRKY genes, differing in the group I-derived lineage.55 All hypotheses could clarify the evolution of OnWRKYs, but only partially. Herein, we proposed an all round model of OsWRKY gene evolution determined by the phylogenetic trees along with the sequences with the WRKY domains (Fig. 9). An ancient IIc WRKY gene is the ancestor of all WRKY genes. Group IIc WRKY genes are most diverse. Phylogenetic analyses of OnWRKY domains show that the subgroup IIc domains have been clustered into two clades (Fig. 7). Nonetheless, the bootstrap values for clade IIc1 and IIc2 had been exceptionally low (20). Furthermore, the topology with the complete protein sequence tree is similar to that of the domain tree regarding most clades.

It is frequently believed that group IIc WRKYs evolved from group Ia WRKYs.2,32,48 Some of our data assistance this hypothesis. First, the C-terminal WRKY domains of group Ia proteins are very related towards the subgroup IIc p.
