ps2, the gene responsible for functional sterility in tomato, due to non-dehiscent anthers, is the result of a mutation in a novel polygalacturonase gene [PDF]
The recessive mutation ps-2, which appeared spontaneously in tomato, confers functional male sterility due to non-dehiscent anthers. In this study, we isolated and characterized the PS-2 gene.

Improvement of experimental testing and network training conditions with genome-wide microarrays for more accurate predictions of drug gene targets [PDF]
BACKGROUND: Genome-wide microarrays have been useful for predicting chemical-genetic interactions at the gene level. However, interpreting genome-wide microarray results can be overwhelming due to the vast output of gene expression data combined with off-

Osmotic regulation of gene action. [PDF]
Most reactions involved in gene translation systems are ionic-dependent and may be explained in electrostatic terms. However, a number of observations of equilibria and rate processes making up the overall reactions clearly indicate that there is still an enormous gap between the rough picture of the mechanism of ionic regulation and the detailed ...

Chromosome variation and gene action [PDF]
The causal relationships responsible for the association of phenotypic variation with chromosomal aberrations are poorly understood. An approach to the study of the primary consequences of chromosomal imbalance is the search for deviations at the level of appropriate gene products. Recent progress in gene mapping combined with the present techniques of

Regulation of Murine Class I Genes by Interferons is Controlled by Regions Located Both 5' and 3' to the Transcription Initiation Site [PDF]
Interferons regulate the expression of a large number of mammalian genes, including the major histocompatibility antigen genes. To investigate the mechanisms involved in interferon action, we have analyzed the ability of murine H-2Ld and H-2Dd DNA ...

“A Gene for. . .”:The Nature of Gene Action in Psychiatric Disorders [PDF]
A central phrase in the new "GeneTalk" is "X is a gene for Y," in which X is a particular gene on the human genome and Y is a complex human disorder or trait. This article begins by sketching the historical origins of this phrase and the concept of the gene-phenotype relationship that underlies it.
