Species identification of Fusarium spp.causing root rot on strawberry
In this study,155 isolates of Fusarium were isolated from the diseased roots of strawberry with the symptom of root rot,which were collected from thirteen provinces,municipalities,and autonomous regions across China from 2021 to 2022.The obtained 155 Fusarium isolates were identified to be eight species(namely F.acuminatum,F.asiaticum,F.commune,F.equiseti,F.fujikuroi,F.oxysporum,F.proliferatum,and F.solani)based on morphological characteristics and sequence analyses of internal transcribed spacer of ribosomal DNA(rDNA-ITS)and translation elongation factor-1 alpha(TEF-1α),with F.oxysporum(108 isolates,69.68%)being predominant.Results of pathogenicity test confirmed that thirty-one representative isolates belonging to these eight species of Fusarium could induce the symptom of root rot on strawberry roots,showing that they were pathogenic on strawberry roots.The average disease incidence(98.62%)and disease index(79.87)of strawberry roots caused by F.oxysporum were higher than those of the seven other species of Fusarium.To the best of our knowledge,this is the first report of F.asiaticum,F.commune,F.fujikuroi,and F.proliferatum causing strawberry root rot in China.
