Abstract:	The entomopathogenic fungus Beauveria bassiana is widely used for insect pest control and can produce three distinct infective unit types under different nutritional and environmental conditions: aerial conidia, blastospores, and submerged conidia. Here, we identified endophytic colonization ability and existing forms of the three types of B. bassiana infective units after inoculating Arabidopsis plants via soil drenching, and tested their effects on their presence mold disease caused by Botrytis cinerea. We found that all B. bassiana infective unit types colonized Arabidopsis leaves, with germinating and producing hyphae by hydrophilic blastopores and submerged conidia; further, we showed that blastospores were more effective in defending against B. cinerea, compared with aerial conidia. These findings suggest that in addition to aerial conidia, the colonization of other two types of entomopathogenic fungal infective units could also have important impacts on plant resistance. This study contributes to better understanding on the function of B. bassiana as fungal endophytes, which could lead to a new paradigm for how to successfully use these organisms in biological control against plant diseases.
