Gene expression in aerial hyphae in response to rep1 deletion in Ustilago maydis

ABSTRACT: The rep1 gene of the maize pathogen Ustilago maydis encodes a pre-pro-protein that is processed in the secretory pathway into 11 peptides. These so-called repellents form amphipathic amyloid fibrils at the surface of aerial hyphae. Strains in which the rep1 gene is inactivated (M-bM-^HM-^Frep1 strain) are affected in aerial hyphae formation. This makes these strains instrumental to assess changes in global gene expression as a consequence of aerial growth. Microarray analysis revealed that only 31 genes in the M-bM-^HM-^Frep1 SG200 strain had a fold change in expression of >= 2. Twenty-two of these genes are up-regulated and half of them encode small secreted proteins (SSPM-bM-^@M-^Ys) with unknown functions. Seven of the SSP genes and two other genes that are over-expressed in the M-bM-^H
