Aspergillus niger MidA, CchA, CrzA, CnaA strains reduced adhesion properties. a Shown are WT and ∆MidA, ∆CchA, ∆CrzA, ∆CnaA conidia in a 1:1 water–oil (glyceryl tributyrate) interface. b qRT-PCR results. Relative expression of RodA genes in ∆MidA, ∆CchA, ∆CrzA and ∆CnaA compared with WT, respectively. c Adhesion properties of A. niger wild type and mutant strains on glass slides. Adhesion number of conidia on coverslips. The values are the means and standard deviations of three independent experiments. ***p < 0.001, **p < 0.01, *p < 0.05 by Student’s t-test
