Leucine-rich repeat receptor-like protein kinases (LRR-RLKs) are vital for plant growth and development, signal transduction, immunity, and play diverse roles in plant defense responses. However, the LRR-RLK genes have not been systematically studied in Vernicia fordii (tung tree), especially its response to Fusarium wilt. Here, we carried out an integrative analysis of LRR-RLKs among five Euphorbiaceae species: Hevea brasiliensis (rubber tree), Manihot esculenta (cassava), Jatropha curcas (physic nut), Ricinus communis (castor bean), and V. fordii, which contained 223, 311, 186, 138, and 167 LRR-RLKs, respectively. Maximum-likelihood tree was estimated using LRR-RLKs of Arabidopsis thaliana as a template, and they allowed us to divide Euphorbiaceae LRR-RLKs into 22 groups. There are 126 segmental and 30 tandem duplications in these Euphorbiaceae genomes by synteny analysis. The tissue-specific expression patterns revealed that V. fordii LRR-RLKs (VfLRR-RLKs) were differentially expressed in various tissues, and some of them exhibited specific expression in meristems tissues, which suggested their potential functions during organ formation and cell fate specification. Two VfLRR-RLK pairs (Vf01G2125 and Vf03G1740, Vf06G2687 and Vf10G1659), which generated by tandem duplication events, were associated with possible resistance to Fusarium wilt infection. The qRT-PCR confirmed these four VfLRR-RLKs contained opposite expression profiles during pathogen infection in V. fordii and V. montana. Taken together, our data systematically analyzed the LRR-RLK family in Euphorbiaceae genomes for the first time. We highlight the putative roles of VfLRR-RLKs in response to Fusarium wilt infection, and VfLRR-RLKs may be further applied in marker-assisted breeding to control Fusarium wilt in V. fordii.
