<i>VfLRR-RLK1</i> benefiting resistance to <i>Fusarium oxysporum</i> reveals infection and defense mechanisms in tung tree.

ABSTRACT: Fusarium wilt, caused by Fusarium oxysporum f. sp. fordiis in Vernicia fordii, manifests as severe symptoms that significantly reduce global tung oil yield. However, the molecular-mechanisms of the Vernicia-Fusarium interaction are yet to be fully elucidated. Here, we cloned VfLRR-RLK1 from tung tree roots, which contained 1134 bp, encoding 378 AA. To further analyze VfLRR-RLK1 function in resistance to Fusarium wilt, we obtained stable T4-generation transgenic Arabidopsis thaliana and tung tree VfLRR-RLK1 virus-induced gene silencing (VIGS) RNAi plants. A. thaliana plants overexpressing VfLRR-RLK1 exhibited more robust root development and markedly increased Fusarium wilt disease resistance. In response to Fusarium wilt
