Project description:Hybrid sturgeon, an ancient fish, has great economic and nutritional value as a source of caviar. Although significant differences exist in the female reproductive capacity under artificial breeding conditions, differential gene expression associated to domesticated female reproductive capacity have never been investigated. In this study, we conducted reference genome-based transcriptome sequencing of 16 individuals from high-yield (H) and low-yield (L) populations, respectively.

Project description:In this study, we utilized the microfluidics chip technology on the gonads of Amur sturgeon to identifiy gender-specific miRNAs. The probes of all miRNAs about 663 published in fish and our novel miRNAs from sturgeon were chosed in the microarray experiment. Above 4µg to 8µg total RNA from one female and one male separativley were performed the miRNA microarray assays.Each probe was repeated five times on the chip to ensure reproducibility of microarray.

Project description:F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor which form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants which have a F1 –like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines “Hybrid Mimics”, in which the characteristics of the F1 Hybrid are stabilized. These Hybrid Mimic lines, like the F1 Hybrid, have larger leaves than the parent plant, the leaves having increased photosynthetic cell numbers, and in some lines increased size of cells, suggesting an increased supply of photosynthate. A comparison of the differentially expressed genes in the F1 Hybrid with those of eight Hybrid Mimic lines has identified metabolic pathways altered in both; these pathways include down regulation of defense response pathways and altered abiotic response pathways. F6 Hybrid Mimic lines are mostly homozygous at each locus in the genome yet retain the large F1-like phenotype. Many alleles in the F6 plants, when they are homozygous, have expression levels different to the level in the parent. We consider this altered expression to be a consequence of trans-regulation of genes from one parent by genes from the other parent. Transregulation could also arise from epigenetic modifications in the F1. The pure breeding Hybrid Mimics have been valuable in probing the mechanisms of hybrid vigor and may also prove to be useful hybrid vigor equivalents in agriculture.
