1. Modelo do ponto crítico para estimar danos causados pela mancha-marrom e oídio em cevada
A cevada (Hordeum vulgaris L.) é a segunda mais importante cultura de inverno no Sul do Brasil. Nessa região, o excesso de chuvas durante a estação de crescimento da cultura favorece o aumento na frequência e intensidade de doenças foliares. O trabalho objetivou determinar as equações de função de dano (EFD) para o patossistema múltiplo mancha-mar

2. Redução da sensibilidade de Blumeria graminis f. sp. hordei ao fungicida triadimenol aplicado em tratamento de sementes
Em experimentos conduzidos em câmara de crescimento com temperatura e fotoperíodo controlados foram testadas duas populações de Blumeria graminis f.sp. hordei oriundas de Guarapuava, PR e de Passo Fundo, RS. Os tratamentos constaram da aplicação do fungicida triadimenol (Baytan 150 SC®) em três doses da formulação comercial: 150; 250 e 350 mL/100 K

7. In Planta Proteomics and Proteogenomics of the Biotrophic Barley Fungal Pathogen Blumeria graminis f. sp. hordei*
To further our understanding of powdery mildew biology during infection, we undertook a systematic shotgun proteomics analysis of the obligate biotroph Blumeria graminis f. sp. hordei at different stages of development in the host. Moreover we used a proteogenomics approach to feed information into the annotation of the newly sequenced genome. We analyzed an

8. Gene Expression Profiles of Blumeria graminis Indicate Dynamic Changes to Primary Metabolism during Development of an Obligate Biotrophic PathogenW⃞
cDNA microarrays of Blumeria graminis f sp hordei transcript profiles during the asexual development cycle reveal the dynamics of global gene expression as the fungus germinates, penetrates, feeds on its host, and produces masses of conidia for dispersal. The expression profiles of genes encoding enzymes involved in primary metabolism show that there is a st

9. Recruitment and interaction dynamics of plant penetration resistance components in a plasma membrane microdomain
Many fungal pathogens must enter plant cells for successful colonization. Barley mildew resistance locus o (Mlo) is required for host cell invasion upon attack by the ascomycete powdery mildew fungus, Blumeria graminis f.sp. hordei, and encodes the founder of a family of heptahelical integral membrane proteins unique to plants. Recessively inherited loss-of-

10. Overexpression of barley BAX inhibitor 1 induces breakdown of mlo-mediated penetration resistance to Blumeria graminis
Cell death regulation is linked to pathogen defense in plants and animals. Execution of apoptosis as one type of programmed cell death in animals is irreversibly triggered by cytochrome c release from mitochondria via pores formed by BAX proteins. This type of programmed cell death can be prevented by expression of BAX inhibitor 1 (BI-1), a membrane protein

11. Early H2O2 Accumulation in Mesophyll Cells Leads to Induction of Glutathione during the Hyper-Sensitive Response in the Barley-Powdery Mildew Interaction1
H2O2 production and changes in glutathione, catalase, and peroxidase were followed in whole-leaf extracts from the susceptible (AlgS [Algerian/4* (F14) Man.(S)]; ml-a1 allele) and resistant (AlgR [Algerian/4* (F14) Man.(R)]; Ml-a1 allele) barley (Hordeum vulgare) isolines between 12 and 24 h after inoculation with powdery mildew (Blumeria graminis [DC].

12. Ectopic Expression of Constitutively Activated RACB in Barley Enhances Susceptibility to Powdery Mildew and Abiotic Stress1
Small RAC/ROP-family G proteins regulate development and stress responses in plants. Transient overexpression and RNA interference experiments suggested that the barley (Hordeum vulgare) RAC/ROP protein RACB is involved in susceptibility to the powdery mildew fungus Blumeria graminis f. sp. hordei. We created transgenic barley plants expressing the constitut
