Abstract
Skin and feather follicle morphogenesis are important processes for duck development; however, the mechanisms underlying morphogenesis at the embryonic stage remain unclear. To improve the understanding of these processes, we used transcriptome and weighted gene co-expression network analyses to identify the critical genes and pathways involved in duck skin development. Five modules were found to be the most related to five key stages in skin development that span from embryonic day 8 (E8) to postnatal day 7 (D7). Using STEM software, 6519 genes from five modules were clustered into 10 profiles to reveal key genes. Above all, we obtained several key module genes including WNT3A, NOTCH1, SHH, BMP2, NOG, SMAD3, and TGFβ2. Furthermore, we revealed that several pathways play critical roles throughout the skin development process, including the Wnt pathway and cytoskeletal rearrangement-related pathways, whereas others are involved in specific stages of skin development, such as the Notch, Hedgehog, and TGF-beta signaling pathways. Overall, this study identified the pathways and genes that play critical roles in skin development, which may provide a basis for high-quality down-type meat duck breeding.

Comparison of gene co-networks reveals the molecular mechanisms of the rice (Oryza sativa L.) response to Rhizoctonia solani AG1 IA infection. Funct Integr Genomics 2018; 18:545-557. [PMID: 29730773 PMCID: PMC6097106 DOI: 10.1007/s10142-018-0607-y] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Revised: 03/12/2018] [Accepted: 03/20/2018] [Indexed: 12/16/2022]
Abstract
Rhizoctonia solani causes rice sheath blight, an important disease affecting the growth of rice (Oryza sativa L.). Attempts to control the disease have met with little success. Based on transcriptional profiling, we previously identified more than 11,947 common differentially expressed genes (TPM > 10) between the rice genotypes TeQing and Lemont. In the current study, we extended these findings by focusing on an analysis of gene co-expression in response to R. solani AG1 IA and identified gene modules within the networks through weighted gene co-expression network analysis (WGCNA). We compared the different genes assigned to each module and the biological interpretations of gene co-expression networks at early and later modules in the two rice genotypes to reveal differential responses to AG1 IA. Our results show that different changes occurred in the two rice genotypes and that the modules in the two groups contain a number of candidate genes possibly involved in pathogenesis, such as the VQ protein. Furthermore, these gene co-expression networks provide comprehensive transcriptional information regarding gene expression in rice in response to AG1 IA. The co-expression networks derived from our data offer ideas for follow-up experimentation that will help advance our understanding of the translational regulation of rice gene expression changes in response to AG1 IA.
