1. Microbial interactions: ecology in a molecular perspective
ABSTRACT The microorganism-microorganism or microorganism-host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype sel

2. Caracterização funcional do fator de transcrição GmNAC6 de soja (Glycine max) e padrão de expressão de genes GmNACs em resposta a estímulos bióticos / Functional characterization of GmNAC6 transcription factor from soybean (Glycine max) and expression profile of GmNACs genes in response to biotic stimuli
Os fatores de transcrição da família NAC são específicos de plantas e atuam em eventos de desenvolvimento e resposta de defesa. Além dos sete genes NACs previamente caracterizados (GmNAC1-GmNAC6 e GmATAF), quatro novos genes desta família (Gm82, Gm119, Gm178 e Gm258) foram avaliados em resposta a condições de estresse biótico. GmATAF, GmNAC3 e GmNA

3. Disease Lesion Mimicry Caused by Mutations in the Rust Resistance Gene rp1.
The rp1 locus of maize controls race-specific resistance to the common rust fungus Puccinia sorghi. Four mutant or recombinant Rp1 alleles (rp1-NC3, Rp1-D21, Rp1-MD19, and Rp1-Kr1N) were identified. They condition necrotic phenotypes in the absence of the rust pathogen. These Rp1 lesion mimics fall into three different phenotypic classes: (1) The rp1-NC3 and

4. Aequorin-based measurements of intracellular Ca2+-signatures in plant cells
Due to the involvement of calcium as a main second messenger in the plant signaling pathway, increasing interest has been focused on the calcium signatures supposed to be involved in the patterning of the specific response associated to a given stimulus. In order to follow these signatures we described here the practical approach to use the non-invasive meth

5. Stimulus-Dependent, Promoter-Specific Binding of Transcription Factor WRKY1 to Its Native Promoter and the Defense-Related Gene PcPR1-1 in ParsleyW⃞
WRKY transcription factors form a large family that plays a role in plant responses to biotic stress and during senescence. Defining in vivo relevant WRKY/promoter relationships has been hampered by the factors' indiscriminate binding to known W box DNA elements and their possible genetic redundance. Employing chromatin immunoprecipitations (ChIP) of culture

6. Spatiotemporal Patterning of Reactive Oxygen Production and Ca2+ Wave Propagation in Fucus Rhizoid Cells
Both Ca2+ and reactive oxygen species (ROS) play critical signaling roles in plant responses to biotic and abiotic stress. However, the positioning of Ca2+ and ROS (in particular H2O2) after a stress stimulus and their subcellular interactions are poorly understood. Moreover, although information can be encoded in different patterns of cellular Ca2+ signals,
