ABSTRACT: Hybridization of one kidney of cortisol treated fish vs. one kidney of control fish. Kidneys were collected from untreated juvenile sea bream (n=4) and from fish, which received for 72h a coconut-oil implant containing 10mg/Kg (fish wet weight) (n=4) cortisol. Experiments were carried out at the University of the Algarve, Portugal in accordance with National legislation for the welfare of animals. Experiments were conducted in two 125 l cylindriconical tanks supplied with a continuous through-flow of oxygenated seawater at 20+1 Â°C using juvenile sea bream (25 g + 3 g) adapted for 1 week to the experimental conditions. One tank contained 8 untreated fish (control) and the other tank 8 cortisol treated fish and the end of experiments fish were removed form tanks, decapitated and the kidneys rapidly removed and place in RNAlater (Qiagen) at â20 Â°C. No mortality occurred in the control tank but 2 fish died in the cortisol treated tank.

Large-scale gene expression studies were performed for one of the main European aquaculture species, the gilthead sea bream Sparus auratus L. For this purpose, a cDNA microarray containing 10,176 clones from a cDNA library of mixed embryonic and larval stages was constructed. In addition to its importance for aquaculture, the taxonomic position and the relatively small genome size of sea bream makes it a prospective model for evolutionary biology and comparative genomics. However, so far, no lar ...[more]

Project description:Heterosis is the phenomenon whereby the progeny of particular inbred lines have enhanced agronomic performance relative to both parents. Although several hypotheses have been proposed to explain this fundamental biological phenomenon, the responsible molecular mechanisms have not been determined. The maize inbred lines B73 and Mo17 produce a heterotic F1 hybrid. Global patterns of gene expression were compared in seedlings of these three genotypes using a microarray that contains 13,999 cDNAs. Using an estimated 15% false discovery rate as a cut-off, 1,367 ESTs (9.8%) were identified as being significantly differentially expressed among genotypes. All possible modes of gene action were observed, including additivity, high- and low-parent dominance, under-dominance, and over-dominance. The largest proportion of the ESTs (78%, 1,062/1,367) exhibited expression patterns that are not statistically distinguishable from additivity. Even so, 22% of the differentially regulated genes exhibited non-additive modes of gene expression. Classified on the basis of significant pair-wise comparisons of genotype means, 181 of these 305 genes exhibited high-parent dominance and 23 exhibited low-parent dominance. In addition, 44 genes exhibited under- or over-dominant gene action. These findings are consistent with the hypothesis that multiple molecular mechanisms contribute to heterosis, including over-dominance Keywords: Genotype Comparison The inbreds B73 (Schnable Lab Accession #660) and Mo17 (Schnable Lab Accession #2618) used in this study were derived by self-pollination from stocks originally obtained from Don Robertson (Iowa State University) and Mike Lee (Iowa State University), respectively. Mo17 was crossed as a female by B73 to generate the F1. Kernels from three different seed sources (ears) per genotype were used in the experimental design. Prior to microarray analyses genotypes were confirmed by genotyping DNA extracted from each seed source using co-dominant IDP genetic markers that distinguish B73 from Mo17 (Fu et al., in preparation). Ten biological replications of B73, Mo17, and their F1 (Mo17xB73) were grown under highly controlled conditions in a randomized complete block design. For each replication, the B73, Mo17, and F1 samples were hybridized to three two-color cDNA microarrays using a loop design such that each loop included all pairwise comparisons between genotypes. RNA pools for each genotype were alternately labeled providing dye balance within each loop. After hybridization, one biological replicate was removed due to poor quality. The final analysis incorporated 27 microarray slides (3 slides for each of nine high-quality biological replicates).

Project description:Natural Antisense Transcripts (NATs) can regulate gene expression by virtue of their ability to form double-stranded RNA duplexes. To investigate NATs in the maize transcriptome, cDNAs from seedling of two inbred lines (B73 and Mo17) were hybridized to an oligonucleotide microarray designed to validate the expression of in silico detected NATs and to screen for NATs that can anneal to a random set of 3â UTRs and selected repeats found in 3â UTRs regions. Quantitative Real-Time PCR experiments were conducted to determine the minimum detection threshold of microarray experiment and to thereby identify genes for which both sense and antisense transcripts accumulate to detectable levels. Two independent approaches, strand-specific RT-PCR and S1 nuclease assays were conducted to validate the results of the microarray experiment. Based on these conservative assays, NATs accumulate in seedlings that can anneal to over 70% of a random set of maize genes. In addition, both sense and antisense transcripts anneal to more than 80% of a set of maize repeats. Significantly, sense and antisense transcripts exhibit significant different expression patterns between the two genotypes. Based on these findings we hypothesize that interactions between sense and antisense transcripts may contribute to the differential patterns of gene expression in maize hybrids and to heterosis. Keywords: Global antisense transcripts profiling between two maize inbreds To systematically identify NATs in maize, we employed multiple strategies to computationally identify putative antisense transcripts from our partial genome assembly (MAGIs) and a collection of ESTs we sequenced with known sequence orientation. Additionally, we randomly sampled and surveyed maize UTRs which often harbor transposons. Strand-specific oligonucleotides which can hybridize to the antisense strand were designed and spotted with together with the oligonucleotides hybridizing sense strands on a custom, strand-specific oligoarray, providing the first global expression profiling study of NATs in maize UTRs. In total, 10 biological replication were conducted to compare the global gene expression profiles between two maize genotypes (B73 and Mo17).

Project description:Vegetative phase change is the developmental transition from the juvenile phase to the adult phase during which a plant becomes competent for sexual reproduction. Gain of ability to flower is often accompanied by changes in patterns of differentiation in newly forming vegetative organs. In maize, juvenile leaves differ from adult leaves in morphology, anatomy, and cell wall composition. Whereas the normal sequence of juvenile followed by adult is repeated with every sexual generation, this sequence can be altered in maize by the isolation and culture of the shoot apex from an adult phase plant; an âadultâ meristem so treated reverts to forming juvenile vegetative organs. To investigate the molecular differences between the juvenile and adult phases in maize comparisons among two juvenile samples, leaf 4 and culture-derived leaf 3 or 4, and an adult sample (leaf 9) were made using cDNA microarrays. All samples were leaf primordia at plastochron 6. A gene was scored as âphase specificâ if it was up- (or down-) regulated in both juvenile samples compared to the adult sample with at least a twofold-change in gene expression at P-value less than or equal to 0.005. Some 221 ESTs up-regulated in juvenile and 28 ESTs up-regulated in adult were identified. Altered patterns of expression of selected ESTs in the phase change mutants Tp2, d1 and gl15 further confirmed these genes as being phase-specific and allowed us to position these genes in the known genetic hierarchy regulating phase change. Keywords: Transcript profiling among seed-derived juvenile leaf 4 and adult leaf 9 and culture-rejuvenated leaf 3 or 4 in maize To identify juvenile or adult specific ESTs, total RNA from leaf primordia at plastochron 6 (P6) was isolated from leaves 4 (L4) and 9 (L9) from seed-derived plants and leaf 3 or 4 (RL3/4) from culture-derived plants. For each of six biological replications, each of the three pairwise comparisons of P6-staged leaf primordia from L4, L9 and RL3/4 was made on one slide. With six biological replications and three slides per replication (L4 vs. L9, L9 vs. RL3/4, RL3/4 vs. L4), this replicated loop design used a total of 18 slides. To ensure dye balance, each of the 18 target samples was measured once with Cy3 labeling and once with Cy5 labeling.
