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.
