acdA was originally annotated as AN2264.3 at the Broad Institute (http://www.broadinstitute.org/annotation/genome/aspergillus_group/MultiHome.html) or as AN2264 at the Aspergillus Genome Database (http://www.aspergillusgenome.org/). The sequences were fusions of three genes on both databases and the Broad Institute has re-annotated the sequence (acdA is now ANID_12335.1). However, the new annotation failed to annotate the correct stop codon. Therefore, a re-annotation was performed with the new coordinates shown below.

acdB was originally annotated as AN10834.3 at the Broad Institute or as AN10834 at the Aspergillus Genome Database. Re-sequencing of the gene detected an error in the original genome sequence. The sequence obtained from both databases contain an additional C at position 393, which leads to a frameshift and an inability to establish the correct start codon at position 364. Re-annotation was performed with the new coordinates shown below.

aoxB was originally annotated as AN6765.3 at the Broad Institute or as AN6765 at the Aspergillus Genome Database. Alignments with S. cerevisiae FOX1 and A. nidulans aoxA suggested the occurrence of an additional intron. Re-annotation was performed with the new coordinates shown below.

Figure S1: Phylogenetic tree of Fox1 and homologues including the putative FA-CoA oxidases AoxA and AoxB

The phylogenetic tree was produced using ClustalW (accurate) (Thompson et al. 1994), Seqboot and Protpars (Felsenstein 1989) in Biomanager by ANGIS (http://www.angis.org.au). The tree was edited using TreeView (Page 1998) and is shown as a radial tree. Bootstrap values and scale bar (amino acid substitutions/site) are displayed. No out-group has been selected.

The tree of AoxA and AoxB was produced using alignments of following homologous proteins: A. clavatus 1: ACLA_007790, A. clavatus 2: ACLA_094690 re-annotated; A. flavus 1: AFL2G_00480.2, A. flavus 2: AFL2G_06552.2 re-annotated; A. flavus 3: AFL2G_11284.2; A. fumigatus: Afu7g06090 and Afu7g06100 re-annotated; A. nidulans AoxA: AN6752.3, A. nidulans AoxB: AN6765.3 re-annotated; A. niger: e_gw1_5.1444.1; A. oryzae 1: AO090005000479, A. oryzae 2: AO090010000014, A. terreus 1: ATEG_04376.1, A. terreus 2: ATEG_06288.1, A. terreus 3: ATEG_06308.1, A. terreus 4: ATEG_09798.1; B. cinerea: BC1G_08482.1; C. albicans 1: orf19.1652, C. albicans 2: orf19.1655, C. albicans 3: orf19.5723; C. immitis 1: CIMG_01877.3; C. immitis 2: CIMG_10832.3, C. immitis 3: CIMG_11894.3 re-annotated; F. graminearum: FGSG_02287.3; N. fischeri: NFIA_027340; S. cerevisiae Fox1: YGL205W; Y. lipolytica 1: YALI0C23859, Y. lipolytica 2: YALI0D24750, Y. lipolytica 3: YALI0E06567, Y. lipolytica 4: YALI0E27654, Y. lipolytica 5: YALI0E32835, Y. lipolytica 6: YALI0E10857.


Figure S2: Alignment of N. crassa NCU01181.3 and the A. nidulans putative FA-CoA dehydrogenases AcdA and AcdB

The amino acid sequence of N. crassa NCU01181.3 and the re-annotated protein sequences of A. nidulans AcdA (AN2264.3) and AcdB (AN10834.3) have been aligned using the programs ClustalW (accurate) (Thompson et al. 1994) and Boxshade in Biomanager (http://www.angis.org.au). Identical amino acids are shaded in black, similar amino acids in grey. The acyl-CoA dehydrogenase middle domain (first box) and C-terminal domain (second box) are marked.


Figure S3: Localisation of the GFP-AcdA and GFP-AcdB

Spore suspensions of strains expressing the GFP fusion proteins in a wild-type (WT) background, MH11914 (GFP-AcdA) and MH11915 (GFP-AcdB), or in pexE background, MH11920 (GFP-AcdA) and MH11921 (GFP-AcdB) were inoculated in supplemented minimal media and incubated overnight at 24ºC. Microscope slides were prepared, viewed and photographed. Hyphae were visualised by DIC and GFP expression was detected as described in Material and Methods. The magnification is 125x; the scale bar represents 20µm. Each construct is listed above to the appropriate panel of photos.


Figure S4: Occurrence of the CCGAGG sequence in the promoters of acdA and acdB and induction of acdA(p)lacZ and acdB(p)lacZ by different carbon sources

1kb of the promoter (p) of acdA (a) and acdB (b) (-1000 to –1) is shown as a schematic overview in intervals of 100bp. CCGAGG sequences are represented by triangles. The numbers above the triangles indicate location of the CCGAGG sequence.

ß-galactosidase assays of acdA(p)lacZ (a) and acdB(p)lacZ (b) in different wild-type, farA∆, farB∆, scfA∆ and farA∆farB∆ background were performed. All strains were grown in supplemented glucose-minimal media for 16h at 37ºC. Mycelia were washed with and transferred to supplemented media containing either 1% glucose, 50mM proline, 10mM butyrate or 2.5mM oleate as sole carbon source for an additional 4h. Standard error was calculated from three independent experiments. All assays are recorded in units per minute per mg protein, but the scales differ between the two figures. The strains used for acdA(p)lacZ were MH11566, MH11648, MH11649, MH1150 and MH12008. For acdB(p)lacZ, the strains used were MH12055, MH12129, MH12130, MH12131.
