Comparative genomics reveals mobile pathogenicity chromosomes in Fusarium Inra
Ma, L.J.; Van der Does, C.; Borkovich, K.A.; Coleman, J.J.; Daboussi, M.J.; di Pietro, A.; Dufresne, M.; Freitag, M.; Grabherr, M.; Henrissat, B.; Houterman, P.M.; Kang, S.; Shim, W.B.; Woloshuk, C.; Xie, X.; Xu, J.R.; Antoniw, J.; Baker, S.E.; Bluhm, B.H.; Breakspear, A.; Brown, D.W.; Butchko, R.A.E.; Chapman, S.; Coulson, R.; Coutinho, P.M.; Danchin, E.; Diener, A.; Gale, L.R.; Gardiner, D.M.; Goff, S.; Hammond-Kosack, K.E.; Hilburn, K.; Hua-Van, A.; Jonkers, W.; Kazan, K.; Kodira, C.D.; Koehrsen, M.; Kumar, L.; Lee, Y.H.; Li, L.; Manners, J.M.; Miranda-Saavedra, D.; Mukherjee, M.; Park, G.; Park, J.; Park, S.Y.; Proctor, R.H.; Regev, A.; Ruiz-Roldan, C.; Sain, D.; Sakthikumar, S.; Sykes, S.; Schwartz, D.C.; Turgeon, B.G.; Wapinski, I.; Yoder, O.; Young, S.; Zeng, Q.; Zhou, S.; Galagan, J.; Cuomo, C.; Kistler, H.C.; Rep, M..
Fusarium species are among the most important phytopathogenic and toxigenic fungi. To understand the molecular underpinnings of pathogenicity in the genus Fusarium, we compared the genomes of three phenotypically diverse species: Fusarium graminearum, Fusarium verticillioides and Fusarium oxysporum f. sp. lycopersici. Our analysis revealed lineage-specific (LS) genomic regions in F. oxysporum that include four entire chromosomes and account for more than one-quarter of the genome. LS regions are rich in transposons and genes with distinct evolutionary profiles but related to pathogenicity, indicative of horizontal acquisition. Experimentally, we demonstrate the transfer of two LS chromosomes between strains of F. oxysporum, converting a non-pathogenic...

FOLy: An integrated database for the classification and functional annotation of fungal oxidoreductases potentially involved in the degradation of lignin and related aromatic compounds Inra
Levasseur, A.; Piumi, F.; Coutinho, P.M.; Rancurel, C.; Asther, M.; Delattre, M.; Henrissat, B.; Pontarotti, P.; Asther, M.; Record, E..
The breakdown of lignin by fungi is a key step during carbon recycling in terrestrial ecosystems. This process is of great interest for green and white biotechnological applications. Given the importance of these enzymatic processes, we have classified the enzymes potentially involved in lignin catabolism into sequence-based families and integrated them in a newly developed database, designated Fungal Oxidative Lignin enzymes (FOLy). Families were defined after sequence similarity searches starting from protein sequences and validated by the convergence of results with biochemical experiments reported in the literature. The resulting database was applied as a tool for the functional annotation of genomes from different fungi, namely (i) the Basidiomycota...

Multiple lateral gene transfers and duplications have promoted plant parasitism ability in nematodes Inra
Danchin, E.; Rosso, M.N.; Vieira, P.; De Almeida, J.; Coutinho, P.M.; Henrissat, B.; Abad, P..
Lateral gene transfer from prokaryotes to animals is poorly understood, and the scarce documented examples generally concern genes of uncharacterized role in the receiver organism. In contrast, in plant-parasitic nematodes, several genes, usually not found in animals and similar to bacterial homologs, play essential roles for successful parasitism. Many of these encode plant cell wall-degrading enzymes that constitute an unprecedented arsenal in animals in terms of both abundance and diversity. Here we report that independent lateral gene transfers from different bacteria, followed by gene duplications and early gain of introns, have shaped this repertoire. We also show protein immunolocalization data that suggest additional roles for some of these cell...

Obligate biotrophpy features unraveled by the genomic analysis of rust fungi Inra
Duplessis, S.; Cuomo, CA; Lin, YC; Aerts, A.; Tisserant, E.; Veneault-Fourrey, C.; Joly, DL; Hacquard, S.; Amselem, J.; Cantarel, B.l; Chin, R.; Coutinho, P.M.; Feau, N.; Field, M.; Frey, P.; Gelhaye, É.; Goldberg, J.; Grabherr, M.G.; Kodira, C.D.; Kohler, A.; Kues, U.; Lindquist, E.A.; Lucas, M; Mago, R.; Mauceli, E.; Morin, E.; Murat, C.; Pangilinan, J.L.; Park, R.; Pearson, M.; Quesneville, H.; Rouhier, N.; Sakthikumar, S.; Salamov, A.A.; Schmutz, J.; Selles, B.; Shapiro, H.; Tanguay, P.; Tuskan, G.A.; Henrissat, B.; Van de Peer, Y.; Rouze, P.; Ellis, J.G.; Dodds, P.N.; Schein, J.E.; Zhong, S.; Hamelin, R.C.; Grigoriev, I.V.; Szabo, L.J.; Martin, F..
Rust fungi are some of the most devastating pathogens of crop plants. They are obligate biotrophs, which extract nutrients only from living plant tissues and cannot grow apart from their hosts. Their lifestyle has slowed the dissection of molecular mechanisms underlying host invasion and avoidance or suppression of plant innate immunity. We sequenced the 101-Mb genome of Melampsora larici-populina, the causal agent of poplar leaf rust, and the 89-Mb genome of Puccinia graminis f. sp. tritici, the causal agent of wheat and barley stem rust. We then compared the 16,399 predicted proteins of M. larici-populina with the 17,773 predicted proteins of P. graminis f. sp tritici. Genomic features related to their obligate biotrophic lifestyle include expanded...

Secretome analysis of Phanerochaete chrysosporium strains CIRM-BRFM41 grown on softwood Inra
Ravalason, H.; Jan, G.; Mollé, D.; Pasco, M.; Coutinho, P.M.; Lapierre, C.; Pollet, B.; Bertaud, F.; Petit-Conil, M.; Grisel, S.; Sigoillot, J.C.; Asther, M.; Gimbert, I..
Abstract Proteomic analysis was performed to determine and differentiate the composition of the secretomes of Phanerochaete chrysosporium CIRM-BRFM41, a peroxidasehypersecretory strain grown under ligninolytic conditions and on softwood chips under biopulping conditions.Extracellular proteins from both cultures were analyzed by bidimensional gel electrophoresis and matrix-assisted laserdesorption/ionization time-of-flight tandem mass spectrometry.A total of 37 spots were identified. The secretome in liquid synthetic medium comprised mainly peroxidases,while several wood-degrading enzymes and enzymes involved in fungal metabolism were detected in biopulping cultures on softwood. This prompted an analysis of the impact of secretome modulation in the presence...

The genome of Nectria haematococca: contribution of supernumerary chromosomes to gene expansion Inra
Coleman, J.J.; Rounsley, S.D.; Rodriguez-Carres, M.; Kuo, A.; Wasmann, C.C.; Grimwood, J.; Schmutz, J.; Taga, M.; White, G.J.; Zhou, S.; Schwartz, D.C.; Freitag, M.; Ma, L.J.; Danchin, E.; Henrissat, B.; Coutinho, P.M.; Nelson, D.R.; Straney, D.; Napoli, C.A.; Barker, B.M.; Gribskov, M.; Rep, M.; Kroken, S.; Molnár, I.; Rensing, C.; Kennell, J.C.; Zamora, J.; Farman, M.L.; Selker, E.U.; Salamov, A.; Shapiro, H.; Pangilinan, J.; Lindquist, E.; Lamers, C.; Grigoriev, I.V.; Geiser, D.M.; Covert, S.F.; Temporini, E.; VanEtten, H.D..
The ascomycetous fungus Nectria haematococca, (asexual name Fusarium solani), is a member of a group of >50 species known as the "Fusarium solani species complex". Members of this complex have diverse biological properties including the ability to cause disease on >100 genera of plants and opportunistic infections in humans. The current research analyzed the most extensively studied member of this complex, N. haematococca mating population VI (MPVI). Several genes controlling the ability of individual isolates of this species to colonize specific habitats are located on supernumerary chromosomes. Optical mapping revealed that the sequenced isolate has 17 chromosomes ranging from 530 kb to 6.52 Mb and that the physical size of the genome, 54.43 Mb,...
