TMEM37 and infection: Since the limited decreases of the ECE and Pr1 activities hardly accounted for the abolished host infection of the Δssr4 mutant via cuticular penetration, we evaluated radial growth rates of each strain on rich SDAY, minimal CDA (CDB plus agar) and 34 CDAs amended with different carbon (sugars or polyols) or nitrogen (inorganic or organic) sources by spotting 1 μl of a 106 conidia/ml suspension per plate for colony initiation.
