First report of Pythium recalcitrans infecting flue-cured tobacco

In July 2014, an unknown Pythium sp. was isolated from the rhizosphere soil of flue-cured tobacco ( Nicotiana tabacum ) in Luoyang of China. Based on morphological characteristics and phylogenetic analysis of Inter Transcribed Spacer sequences, the pathogen was identified as Pythium recalcitrans Moralejo. The result of the pathogenicity test showed that Pythium recalcitrans could infect the seedlings of flue-cured tobacco.
