Abstract
conidia/mL-1) around the stem base of each plant, 30 plant were inoculated. Thirty control seedlings received sterilized water. All treatments were maintained for 30 days under greenhouse conditions with a 12-h light/dark photoperiod at 25±0.5℃ and 70% relative humidity. The assay was conducted three times. Root rot and foliage chlorosis similar to the ones observed on infected plants in the field were observed on the inoculated tobacco seedlings, whereas the control seedlings remained asymptomatic after 30 days (Figure1 E). The pathogen isolated from the inoculated plant exhibited morphological characteristics identical to F. sinensis and was identified by a partial EF1-α gene sequence. This disease has previously been reported as the causal agent of root and crown rot of wheat in China (Zhao and Lu 2008; Xu et al. 2018). To our knowledge, this is the first report of F. sinensis causing root rot on tobacco in China.
