Gene Expression Signatures from Three Genetically Separable Resistance Gene Signaling Pathways for Downy Mildew Resistance1[w]

From: Plant Physiology | Date: June 1, 2004| Author: Chang, Hur-Song; Et al; McDowell, John M; Weigman, Victor J; Eulgem, Thomas | Copyright information

Resistance gene-dependent disease resistance to pathogenic microorganisms is mediated by genetically separable regulatory pathways. Using the GeneChip Arabidopsis genome array, we compared the expression profiles of approximately 8,000 Arabidopsis genes following activation of three RPP genes directed against the pathogenic oomycete Peronospora parasitica. Judicious choice of P. parasitica isolates and loss of resistance plant mutants allowed us to compare the responses controlled by three ge...

Gene expression: better tools: more complex results.(Cover story)
Bioscience Technology ; Gene expression has become a mainstream technique in biology, medicine, and drug development. Broadly speaking, gene expression comes in two flavors: analytical and functional. The former refers to detecting and quantifying genes, especially by comparing two samples (treated/untreated,

Compensatory cis-trans Evolution and the Dysregulation of Gene Expression in Interspecific Hybrids of Drosophila
Genetics ; ABSTRACT Hybrids between species are often characterized by novel gene-expression patterns. A recent study on allele-specific gene expression in hybrids between species of Drosophila revealed cases in which cis-and trans-regulatory elements within species had coevolved in such a way that changes in

Gene Expression Profiling Reflects Physiological Processes in Salt Acclimation of Synechocystis sp. Strain PCC 6803(1)
Plant Physiology ; The kinetics of genome-wide responses of gene expression during the acclimation of cells of Synechocystis sp. PCC 6803 to salt stress were followed by DNA-microarray technique and compared to changes in main physiological parameters. During the first 30 min of salt stress, about 240 genes became
The Tomato Transcription Factor Pti4 Regulates Defense-Related Gene Expression via GCC Box and Non-GCC Box cis Elements(W)
Plant Cell ; The tomato transcription factor Pti4, an ethylene-responsive factor (ERF), interacts physically with the disease resistance protein Pto and binds the GCC box cis element that is present in the promoters of many pathogenesis-related (PR) genes. We reported previously that Arabidopsis plants
Toward a Neutral Evolutionary Model of Gene Expression
Genetics ; ABSTRACT We introduce a stochastic model that describes neutral changes of gene expression over evolutionary time as a compound Poisson process where evolutionary events cause changes of expression level according to a given probability distribution. The model produces simple estimators for model
