| Title | OsWRKY114 Is a Player in Rice Immunity against <i>Fusarium fujikuroi</i>. | |
|
Abstract: Every year, invasive pathogens cause significant damage to crops. Thus, identifying genes conferring broad-spectrum resistance to invading pathogens is critical for plant breeding. We previously demonstrated that OsWRKY114 contributes to rice (<i>Oryza sativa</i> L.) immunity against the bacterial pathovar <i>Xanthomonas oryzae</i> pv. <i>oryzae</i> (<i>Xoo</i>). However, it is not known whether OsWRKY114 is involved in defense responses to other pathogens. In this study, we revealed that OsWRKY114 enhances innate immunity in rice against the fungal pathogen <i>Fusarium fujikuroi</i>, which is the causal agent of bakanae disease. Transcript levels of various gibberellin-related genes that are required for plant susceptibility to <i>F. fujikuroi</i> were reduced in rice plants overexpressing <i>OsWRKY114</i>. Analysis of disease symptoms revealed increased innate immunity against <i>F. fujikuroi</i> in <i>OsWRKY114</i>-overexpressing rice plants. Moreover, the expression levels of <i>OsJAZ</i> genes, which encode negative regulators of jasmonic acid signaling that confer immunity against <i>F. fujikuroi</i>, were reduced in <i>OsWRKY114</i>-overexpressing rice plants. These results indicate that OsWRKY114 confers broad-spectrum resistance not only to <i>Xoo</i> but also to <i>F. fujikuroi</i>. Our findings provide a basis for developing strategies to mitigate pathogen attack and improve crop resilience to biotic stress. |
