1. IDENTIFICAÇÃO DE PROTEÍNAS ANTIMICROBIANAS DE FLORES DE ALECRIM-PIMENTA (Lippia sidoides): UMA NOVA ESTRATÉGIA NO COMBATE A PATÓGENOS
Um dos principais problemas mundiais na agricultura está diretamente relacionado às enormes perdas na produção causada por fungos fitopatogenicos, onde sua infecção nas culturas se dá desde o plantio até a pós- colheita. O fungo Botrytis cinerea, causador do mofo cinzento em mais de 200 espécies de plantas é um grande problema no agronegócio em t

2. Caracterização de genes análogos de resistência (RGAs) em cultivares de Musa acuminata contrastantes em resistência à estresses bióticos.
Many cultivars of bananas (Musa spp.) are triploid or sterile diploid and their evolution occurs only through somatic mutation. As a result, this culture may lack resistance to pests and diseases. Several resistance genes (R genes) have been characterized in plants, conferring resistance to bacteria, fungi, nematodes and viruses. The characterization of resi

3. Identificação e caracterização de um análogo de gene de resistência (AGR) da família de Caricaceae Dumort
A maioria dos genes de resistência (R) clonados e caracterizados até o momento contém domínios NBS (nucleotide binding site) e LRR (leucine-rich repeat). Dentro destes domínios, encontram-se "motifs" altamente conservados. Análogos de genes de resistência (RGAs) são marcadores genéticos obtidos por uma estratégia, baseada em PCR, que usa primers de

4. Interaction between domains of a plant NBS–LRR protein in disease resistance-related cell death
Many plant disease resistance (R) genes encode proteins predicted to have an N-terminal coiled-coil (CC) domain, a central nucleotide-binding site (NBS) domain and a C-terminal leucine-rich repeat (LRR) domain. These CC–NBS–LRR proteins recognize specific pathogen-derived products and initiate a resistance response that often includes a type of cell deat

5. The Arabidopsis thaliana RPM1 disease resistance gene product is a peripheral plasma membrane protein that is degraded coincident with the hypersensitive response
Disease resistance in plants is often controlled by a gene-for-gene mechanism in which avirulence (avr) gene products encoded by pathogens are specifically recognized, either directly or indirectly, by plant disease resistance (R) gene products. Members of the NBS-LRR class of R genes encode proteins containing a putative nucleotide binding site (NBS) and ca

6. Intragenic recombination and diversifying selection contribute to the evolution of downy mildew resistance at the RPP8 locus of Arabidopsis.
Pathogen resistance (R) genes of the NBS-LRR class (for nucleotide binding site and leucine-rich repeat) are found in many plant species and confer resistance to a diverse spectrum of pathogens. Little is known about the mechanisms that drive NBS-LRR gene evolution in the host-pathogen arms race. We cloned the RPP8 gene (for resistance to Peronospora parasit

7. Ubiquitin ligase-associated protein SGT1 is required for host and nonhost disease resistance in plants
Homologues of the yeast ubiquitin ligase-associated protein SGT1 are required for disease resistance in plants mediated by nucleotide-binding site/leucine-rich repeat (NBS-LRR) proteins. Here, by silencing SGT1 in Nicotiana benthamiana, we extend these findings and demonstrate that SGT1 has an unexpectedly general role in disease resistance. It is required f

8. The Tomato R Gene Products I-2 and Mi-1 Are Functional ATP Binding Proteins with ATPase Activity
Most plant disease resistance (R) genes known today encode proteins with a central nucleotide binding site (NBS) and a C-terminal Leu-rich repeat (LRR) domain. The NBS contains three ATP/GTP binding motifs known as the kinase-1a or P-loop, kinase-2, and kinase-3a motifs. In this article, we show that the NBS of R proteins forms a functional nucleotide bindin

9. A Gain-of-Function Mutation in an Arabidopsis Toll Interleukin1 Receptor–Nucleotide Binding Site–Leucine-Rich Repeat Type R Gene Triggers Defense Responses and Results in Enhanced Disease Resistance
In a screen for suppressors of npr1-5–based salicylic acid (SA) insensitivity, we isolated a semidominant gain-of-function mutation, designated ssi4, that confers constitutive expression of several PR (pathogenesis-related) genes, induces SA accumulation, triggers programmed cell death, and enhances resistance to bacterial and oomycete pathogens. Through m

10. Three genes of the Arabidopsis RPP1 complex resistance locus recognize distinct Peronospora parasitica avirulence determinants.
Plant resistance (R) genes have evolved specific recognition capabilities in defense against pathogens. The evolution of R gene function and maintenance of R gene diversity within a plant species are therefore of great interest. In the Arabidopsis accession Wassilewskija, the RPP1 region on chromosome 3 contains four genetically linked recognition specificit

11. Convergent Evolution of Disease Resistance Gene Specificity in Two Flowering Plant FamiliesW⃞
Plant disease resistance (R) genes that mediate recognition of the same pathogen determinant sometimes can be found in distantly related plant families. This observation implies that some R gene alleles may have been conserved throughout the diversification of land plants. To address this question, we have compared R genes from Glycine max (soybean), Rpg1-b,

12. RPS4-Mediated Disease Resistance Requires the Combined Presence of RPS4 Transcripts with Full-Length and Truncated Open Reading Frames
Arabidopsis RPS4 belongs to the Toll/interleukin-1 receptor (TIR)–nucleotide binding site (NBS)–Leu-rich repeat (LRR) class of disease resistance (R) genes. Like other family members in different plant species, RPS4 produces alternative transcripts with truncated open reading frames. The dominant alternative RPS4 transcripts are generated by retention of
