Abstract

Canker disease of Sichuan pepper (Zanthoxylum bungeanum) has caused a decline in production in northern China over the past xx years. To identify the etiological agent, 38 fungal strains were isolated from symptomatic tissue from trees in five provinces, from Gansu in the northwest to Shandong in the northeast. Isolates were identified by conducting BLASTN searches of NCBI GenBank and phylogenetic analyses of DNA sequence data from the nuclear ribosomal internal transcribed space region (ITS rDNA), a portion of translation elongation factor 1-α (TEF1), and RNA polymerase second largest (RPB2) and second largest (RPB2) subunits. Results of these analyses suggested that 30/38 isolates belonged to two novel fusaria most closely related to the Florida torreya (Torreya taxifolia Arn.) pathogen, Fusarium torreyae, in Florida and Georgia. These three canker-inducing tree pathogens form a novel clade within Fusarium here designated the F. torreyae species complex (FTOSC). BLASTN queries of GenBank also revealed that 5/38 isolates recovered from cankers represented an undescribed phylogenetic species within the F. solani species complex (FSSC) designated FSSC 6. Stem inoculations of all three fusaria on Z. bungeanum resulted in consistent canker symptoms from which all three fusaria were recovered. The two novel fusaria, however, induced significantly larger lesions than FSSC 6. Herein, the two novel Sichuan pepper pathogens are formally described as F. zanthoxylum and F. bungeanum.
