Re-identification of pathogen of bulb black rot of lilies based on DNA barcoding and infection studies

摘要

We used DNA barcoding analysis to re-examine a sclerotial pathogen of bulb black rot of edible lily (Lilium leichtlinii var. tigrinum), previously identified as Sclerotium cepivorum var. tulipae. The barcoding sequence of the pathogens showed high similarity with that of Sclerotium denigrans, and detailed morphological and pathogenic examination confirmed it as S. denigrans, a new record from Japan.
