• species are amongst the most widespread and important canker and dieback pathogens of trees worldwide, with as one of the most common species. However, the information related to the widespread incidence and aggressiveness of among various species causing trunk cankers is still poorly investigated. In this study, the metabolic phenotypic diversity and genomic differences of four Chinese hickory canker-related pathogens, including , and were systematically studied to address the competitive fitness of . Large-scale screening of physiologic traits using a phenotypic MicroArray/OmniLog system (PMs) found has a broader spectrum of nitrogen source and greater tolerance toward osmotic pressure (sodium benzoate) and alkali stress among species. Moreover, the annotation of species-specific genomic information via a comparative genomics analysis found 143 species-specific genes that not only provides crucial cues in the prediction of species-specific function but also give a basis for the development of a molecular identification method. A species-specific primer set Bd_11F/Bd_11R has been designed based on the sequence of species-specific gene for the accurate identification of in disease diagnoses. Overall, this study deepens the understanding in the widespread incidence and aggressiveness of among various species, providing valuable clues to assist in trunk cankers management.
