- The distributions of all LRR-RLKs on the chromosomes were obtained in five Euphorbiaceae genomes, based on the GFF annotation files. In V. fordii, chr 3 (27 VfLRR -RLK genes) and chr 9 (17 VfLRR -RLK genes) contained more LRR-RLKs than the others. Ten VfLRR-RLK genes were not scattered on any chromosomes. The orthologous LRR-RLKs were detected to understand the potential evolutionary mechanisms of the LRR-RLK family in Euphorbiaceae genomes. Here, we observed the conserved collinearity relationships in these five Euphorbiaceae genomes by MCScanX software. Subsequently, 2012 syntenic blocks containing the LRR-RLK gene were found in chromosomes of these five Euphorbiaceae genomes (Fig. 3 and Table S5). Among these syntenic blocks, a total of 624 LRR -RLK genes (114 from V. fordii, 146 from R. communis, 114 from M. esculenta, 165 from H. brasiliensis, and 85 from J. curcas) were present. These data highlight and confirm the correspondence between syntenic blocks gene pairs and phylogenic relationships (Fig. 1). In addition, 401 LRR -RLK genes (i.e. 53 VfLRR -RLKs, 40 RcLRR -RLKs, 197 MeLRR-RLKs, 58 HbLRR-RLKs, and 53 JcLRR -RLKs) were not present in any syntenic blocks, indicating these genes may have evolved from independent duplication events.
- We determined 130 orthologous gene pairs between V. fordii and H. brasiliensis, 98 pairs between V. fordii and M. esculenta, 133 pairs between V. fordii and R. communis, 80 pairs between V. fordii and J. curcas (Fig. 3 and Table S5), indicating the LRR-RLK genes presented different evolutionary mechanisms among different species after being evolved from the same ancestor. Interestingly, we found some gene pairs between V. fordii and J. curcas, but not found between V. fordii and R. communis/M. esculent/H. brasiliensis, implying these orthologous pairs formed after R. communis/M. esculent/H. brasiliensis and evolved from a common ancestor of J. curcas and V. fordii, or these orthologous pairs are lost in V. fordii and R. communis/M. esculent/H. brasiliensis after divergence of these species, such as Vf11G1528/Jatcu.03g000454. Additionally, we also observed many several-for-one collinearity relationships between V. fordii and R. communis/M. esculent/H. brasiliensis/J. curcas, such as Vf05G1797/GT003585/GT003775 and Vf10G0524/Jatcu.09g000179/Jatcu.06g001577, further explaining the divergent expansion patterns of LRR-RLKs in different species during evolution.
