Project description:Gene expression differences between the ovaries of Jingding duck with high and low egg production were assessed using the RNA-Seq technology. A total of 843 differentially expressed genes were identified. These genes have known or potential roles in regulation the egg production. Therefore, they are appealing candidates for further investigation of the gene expression and associated regulatory mechanisms related to egg production of ducks.

Project description:Dongxiang blue-shelled chicken, an indigenous chicken breed in China, has segregated significantly for the dermal hyperpigmentation phenotype. Two lines of the chicken have been divergently selected with respect to comb color for over 20 generations. The recent selection has also resulted in a significant difference in egg production. The red comb line (RCL) chicken produces significantly higher number of eggs than that by the dark comb line (DCL) chicken. The objective of this study was to explore potential mechanisms involved in the relationship between comb color and egg production among chickens. We performed genome-wide association study to identify candidate genes associated with chicken comb color using SNP array data, and we conducted selective sweep analysis to identify putative regions of selection harboring pleiotropic genes affecting both comb color and egg production.

Project description:Purpose: To identify the key regulatory genes and pathways involved in chicken high egg productivon in HPG axis. Methods: A total of 856 Chinese Luhua chicken was raised in poultry breeding farm of Sichuan Agricultural University, the highest two hundred and the lowest two hundred chicken egg production were considered as high egg production (HEP) and low egg production (LEP) according to the total egg number at 300 days of age, respectively, integrated with RNA-seq sequencing of samples of HPG axis (hypothalamus, pituitary gland and ovary) from three HEP and three LEP chickens at 300 days of age. Results: A total 86.7 Gb RNA-seq sequences were generated, and with each library averaged 5.1 Gb. Conclusions: These important data might improve our understanding of reproductive biology of Luhua chicken by providing comprehensive gene expression information at transcriptional level. We indicate that our approach will contribute to the isolation of effective molecular markers that can be used in genetic breeding programs in Chinese domestic Luhua chicken.

Project description:The life cycle of schistosomes is complex, being characterised by a series of distinct parasitic and free-living phases involving an invertebrate snail host, water and a mammalian host. A custom designed oligonucleotide microarray was utilized to profile developmental gene expression in the Asian blood fluke, Schistosoma japonicum during these parasitic and free-living transitions. Total RNAs were isolated from lung schistosomula, juvenile females and males (paired but little or no egg production), adult males and females (paired with full scale egg production), eggs, miracidia, sporocysts and cercariae. We focused on the three distinct environmental phases of the lifecycle - aquatic/snail (eggs, miracidia, sporocysts, cercariae), juvenile (lung schistosomula and paired pre-egg laying adults) and adult (paired males and females, both examined separately) stages.

Project description:Follicular atresia is an important factor affecting reproductive performance. In birds, less than 5% of follicles could complete their development process and mature ovulation, while the other 95% become atretic follicles and eventually degraded3. Yangzhou geese are famous for their high egg production, however, the average number of eggs per goose is 40-80 and the peak laying rate is 40%-50%12. As an important meat source of poultry, the low egg production of goose has seriously affected the production cost and industrialization development. How to avoid follicular atresia and promote its normal development could help to improve egg production. Therefore, understanding the mechanism of follicular atresia in geese is of great significance for improving egg production.Isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled to liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to quantitatively identify differentially expressed proteins (DEPs) between normal and atretic follicles.

Project description:In this analysis, we used microarrays to contrast genome-wide transcript levels in virgin versus mated females before and after infection. We repeated the entire experiment using female mutants that do not form a germline. We found that multiple genes involved in egg production show reduced expression in response to infection, and that this reduction is stronger in virgins than it is in mated females. In germline-less females, expression of egg-production genes was predictably low and not differentially affected by infection. We also identified several immune responsive genes that are differentially induced after infection in virgins versus mated females.
