Development of Specific Primers for Fusarium oxysporum Formae Speciales rapae and matthiolae with an Integrated Multiplex PCR for Distinguishing Four Formae Speciales on Brassicaceae

There are four formae speciales of Fusarium oxysporum responsible for causing yellows of Brassicaceae. Because of crossbreeding among crops, the host ranges of these formae speciales often overlap, making pathogen identification a challenging task. Among these formae speciales, F. oxysporum f. sp. r...

520 |a There are four formae speciales of Fusarium oxysporum responsible for causing yellows of Brassicaceae. Because of crossbreeding among crops, the host ranges of these formae speciales often overlap, making pathogen identification a challenging task. Among these formae speciales, F. oxysporum f. sp. rapae and F. oxysporum f. sp. matthiolae still lack specific primers for pathogen identification. To address this problem, we targeted the secreted in xylem (SIX) genes, known as specific effectors of pathogenic F. oxysporum, for primer design. Through sequence comparison with other formae speciales, we successfully designed specific primers for F. oxysporum f. sp. rapae and F. oxysporum f. sp. matthiolae on SIX14 and SIX9, respectively. Both primer pairs exhibited high specificity in detecting F. oxysporum f. sp. rapae or F. oxysporum f. sp. matthiolae, distinguishing them from 20 nontarget formae speciales of F. oxysporum, five species of phytopathogenic Fusarium, and four other common pathogenic fungi affecting cruciferous plants. Moreover, the effectiveness of these specific primers was validated by detecting the pathogens in infected plants. To further enhance the identification process of the four formae speciales, we combined the two newly designed specific primer pairs with two previously published primer pairs, enabling the establishment of a multiplex PCR method that can accurately distinguish all four formae speciales of F. oxysporum responsible for causing yellows in cruciferous plants in a single reaction
