It was found that the fungus 1403 resembles pathogenic E verticillioides (teleomophy Gibberella moniliforme) in the production of false head or chains and abundant microconidia on the aerial mycelium, but different in the occasional formation of polyphialides with relatively long as well as short mono- phialides, in its typical coiled hyphae and mycelia fusion. Through maximum Parsimony and Bayesian analyses, the fungus 1403 was fur- ther compared with some similar Fusarium species. The results indicated that this endophyte was identified as Fusarium proliferatum based on the analyses of partial 18S and 28S rDNA genes, ITS region, and EF- 1 α gene.展开更多
