Conserved Expression Signatures between Medaka and Human Pigment Cell Tumors

Aberrations in gene expression are a hallmark of cancer cells. Differential tumor-specific transcript levels of single genes or whole sets of genes may be critical for the neoplastic phenotype and important for therapeutic considerations or useful as biomarkers. As an approach to filter out such relevant expression differences from the plethora of changes noted in global expression profiling studies, we searched for changes of gene expression levels that are conserved. Transcriptomes from massive parallel sequencing of different types of melanoma from medaka were generated and compared to microarray datasets from zebrafish and human melanoma. This revealed molecular conservation at various levels between fish models and human tumors providing a useful strategy for identifying expression signatures strongly associated with disease phenotypes and uncovering new melanoma molecules

Brasetto hybrid winter rye

Brasetto is one of the first two hybrid winter (fall) rye (Secale cereale L.) cultivars to be registered for production in Canada. In registration trials, its grain yield was 42 percent higher than the mean of the check entries and 23 percent higher than the highest yielding reference cultivar, Hazlet. It has a very high falling number, which is of special interest in the food market. Except for lower grain protein content and a slightly higher ergot (Claviceps purpurea (Fr.) Tul.) level, the rest of its measured agronomic and quality characters have been better than or within the range of the Fall Rye Co-operative Registration Trial check cultivars in Canada. Its expected endâ use will be primarily for food and feed grain.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Genetic architecture of complex agronomic traits examined in two testcross populations of rye (<it>Secale cereale</it> L.)

<p>Abstract</p> <p>Background</p> <p>Rye is an important European crop used for food, feed, and bioenergy. Several quality and yield-related traits are of agronomic relevance for rye breeding programs. Profound knowledge of the genetic architecture of these traits is needed to successfully implement marker-assisted selection programs. Nevertheless, little is known on quantitative loci underlying important agronomic traits in rye.</p> <p>Results</p> <p>We used 440 F_3:4 inbred lines from two biparental populations (Pop-A, Pop-B) fingerprinted with about 800 to 900 SNP, SSR and/or DArT markers and outcrossed them to a tester for phenotyping. The resulting hybrids and their parents were evaluated for grain yield, single-ear weight, test weight, plant height, thousand-kernel weight, falling number, protein, starch, soluble and total pentosan contents in up to ten environments in Central Europe. The quality of the phenotypic data was high reflected by moderate to high heritability estimates. QTL analyses revealed a total of 31 QTL for Pop-A and 52 for Pop-B. QTL x environment interactions were significant (P < 0.01) in most cases but variance of QTL main effect was more prominent.</p> <p>Conclusions</p> <p>QTL mapping was successfully applied based on two segregating rye populations. QTL underlying grain yield and several quality traits had small effects. In contrast, thousand-kernel weight, test weight, falling number and starch content were affected by several major QTL with a high frequency of occurrence in cross validation. These QTL explaining a large proportion of the genotypic variance can be exploited in marker-assisted selection programs and are candidates for further genetic dissection.</p
