1. Mancha foliar em capim-elefante no Cerrado do Brasil Central causada por Bipolaris maydis.
Bipolaris maydis (Y. Nisik. & C. Miyake) Shoemaker foi consistentemente isolado de plantas de Pennisetum purpureum Schum., com sintomas de manchas foliares, no Cerrado, em 2005 e 2006. Testes de patogenicidade em mudas sadias de capim-elefante, em casa de vegetação, e o subseqüente reisolamento do fungo confirmaram que B. maydis era o agente causal das le

3. Retrotransposon LTR no genoma de Moniliophthora perniciosa e Cochliobolus heterostrophus / LTR retrotransposon in the genome of Moniliophthora perniciosa and Cochliobolus heterostrophus
Retrotransposons do grupo Gypsy/Ty3 são os principais elementos transponíveis encontrados no genoma de fungos fitopatogênicos. Neste trabalho, dois retrotransposons denominados de MpSaci e Sophie foram analisados em Moniliophthora perniciosa e Cochliobolus heterostrophus, respectivamente. MpSaci foi utilizado para avaliar os marcadores moleculares baseado

6. A novel class of gene controlling virulence in plant pathogenic ascomycete fungi
Insertional mutants of the fungal maize pathogen Cochliobolus heterostrophus were screened for altered virulence. One mutant had 60% reduction in lesion size relative to WT but no other detectable change in phenotype. Analysis of sequence at the insertion site revealed a gene (CPS1) encoding a protein with two AMP-binding domains. CPS1 orthologs were detecte

8. A mitogen-activated protein kinase of the corn leaf pathogen Cochliobolus heterostrophus is involved in conidiation, appressorium formation, and pathogenicity: Diverse roles for mitogen-activated protein kinase homologs in foliar pathogens
Fungal pathogens perceive and respond to molecules from the plant, triggering pathogenic development. Transduction of these signals may use heterotrimeric G proteins, and it is thought that protein phosphorylation cascades are also important. We have isolated a mitogen-activated protein kinase homolog from the corn pathogen Cochliobolus heterostrophus to tes

9. Host Physiology and Pathogenic Variation of Cochliobolus heterostrophus Strains with Mutations in the G Protein Alpha Subunit, CGA1
Conserved eukaryotic signaling proteins participate in development and disease in plant-pathogenic fungi. Strains with mutations in CGA1, a heterotrimeric G protein G alpha subunit gene of the maize pathogen Cochliobolus heterostrophus, are defective in several developmental pathways. Conidia from CGA1 mutants germinate as abnormal, straight-growing germ tub

10. Tagged mutations at the Tox1 locus of Cochliobolus heterostrophus by restriction enzyme-mediated integration.
We have used the restriction enzyme-mediated integration insertional mutagenesis procedure to tag the Tox1 locus in the filamentous Ascomycete Cochliobolus heterostrophus. Mutations at other, unselected, loci were also identified and a high proportion (30-50%) of them were tagged. This procedure may be of general utility for simultaneously mutating and taggi

11. Iron Specifically Protects Corn Protoplasts from T-Toxin of Cochliobolus heterostrophus1
Ferric ion reduced the damaging effects of T-toxin, a series of linear β-polyketols produced by the pathogenic fungus Cochliobolus heterostrophus, on leaf mesophyll protoplasts from susceptible T-cytoplasm corn. Of nine metals tested, only ferric and ferrous ions had this effect. Despite the presence of 12 available oxygen atoms in each T-toxin molecule, th

12. Activation of an AP1-Like Transcription Factor of the Maize Pathogen Cochliobolus heterostrophus in Response to Oxidative Stress and Plant Signals
Redox sensing is a ubiquitous mechanism regulating cellular activity. Fungal pathogens face reactive oxygen species produced by the host plant's oxidative burst in addition to endogenous reactive oxygen species produced during aerobic metabolism. An array of preformed and induced detoxifying enzymes, including superoxide dismutase, catalases, and peroxidases
