Re-identification of Fusarium sambucinum Species Complex Strains in Korea and Their Literature Review

Abstract

<i>Fusarium sambucinum</i> species complex (FSAMSC) is an important taxonomic group, causing severe plant diseases. Many studies were carried out on FSAMSC plant diseases in Korea, but only 2 species (<i>F. graminearum</i>, <i>F. sambucinum</i>) from 14 host plants were registered in the List of Plant Disease in Korea. To clarify FSAMSC diversity and their pathogenecity, we examined FSAMSC isolates preserved in the Korean Agricultural Culture Collection. Fifty-seven strains were reidentifed as 7 species (<i>F. asiaticum</i>, <i>F. graminearum</i>, <i>F. vorosii</i>, <i>F. meridionalei</i>, <i>F. boothii</i>, <i>F. kyushuense</i>, <i>F. armeniacum</i>) based on multi-locus sequence typing analysis. According to previous reports and result of this study, 5 species (<i>F. asiaticum</i>, <i>F. graminearum</i>, <i>F. vorosii</i>, <i>F. armeniacum</i>, <i>F. sambucinum</i>) were pathogenic on 24 host plants in FSAMSC, while the pathogenicity of 3 species (<i>F. meridionalei</i>, <i>F. boothii</i>, <i>F. kyushuense</i>) were not clear.
