The transcriptomes for primary panicle in four near-isogenic lines combined of different allele of two major grain length loci GS3 and qGL3 in rice

ABSTRACT: To investigate the genetic relationship between two major grain length loci GS3 and qGL3, we developed the near-isogenic lines (NILs), NIL-GS3 (GS3/qGL3), NIL-qgl3 (gs3/qgl3), NIL-GS3/qgl3 (GS3/qgl3) in the background of 93-11 (gs3/qGL3) by crossing and MAS approach. Four samples was analyzed: three near-isogenic lines (NILs), NIL-GS3 (GS3/qGL3), NIL-qgl3 (gs3/qgl3), NIL-GS3/qgl3 (GS3/qgl3) and their background of 93-11. Every sample had three independed duplications. And the primary panicle with 3-6 cm length from the three NILs and 93-11 were used for RNA preparation and hybrid with Rice Genome OneArray Microarray (Phalanx Biotech Group).

Transcription profiling of Fusarium head blight resistance in Sumai-3 and two susceptible NILs

Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.

Nogo-B protects mice against lipopolysaccharide-induced acute lung injury

Project description:Purpose: Acute lung injury (ALI) is a severe clinical disorder characterized by diffused capillary-alveolar barrier damage and noncardiogenic lung edema induced by excessive inflammation reactions. Nogo-B, a member of the reticulon 4 protein family, plays a critical role in modulating macrophages and neutrophils’ function in inflammation. Its role in ALI remains unclear. Methods: Pulmonary expression of Nogo-B was investigated in a LPS-induced ALI mice model. The effects and the underline mechanisms of Nogo-B expression on the severity of lung injury was assessed using histological examination, Bronchoalveolar lavage fluid (BALF) protein and inflammatory cells and cytokines measurement, and microarray analysis. Results: Nogo-B was normally highly expressed in the lungs of naïve C57BL/6 mice. Intra-tracheal instillation of LPS significantly repressed the Nogo-B expression in lung tissues and BALF cells of ALI mice. In addition, over-expression of pulmonary Nogo-B using an adenovirus vector which expresses a Nogo-B-RFP-3-flag fusion protein (Ad-Nogo-B) significantly prolonged the survival time of mice challenged with lethal dose of LPS. Histological results and BALF protein measurement convinced that Ad-Nogo-B treated mice had less severity of lung injury and alveolar protein exudation, as compared with control adenovirus treated mice (Ad-RFP). They also had higher MCP-1 secretion and alveolar macrophages infiltration, but lower neutrophils infiltration. Finally, using microarray analysis, we identified a protective gene, PTX3, was highly elevated in Ad-Nogo-B treated mice. Conclusions: Nogo-B played a protective role in LPS-induced ALI, which might exert its role through modulation of inflammatory response and PTX3 secretion. A total of 12 samples from mice treated with or without LPS in the presence of Ad-Nogo-B or Ad-RFP transfection (n=3 for each group)

Comparative Transcriptomics of Soybean Near Isogenic Lines in Response to Phytophthora Sojae

Project description:Phytophthora root and stem rot (PRR) of soybean, caused by Phytophthora sojae, is effectively controlled by Rps genes in soybean. Rps genes are race-specific, yet the mechanism of resistance, as well as susceptibility, remains largely unclear. Taking advantage of RNA-seq technology, we sequenced the transcriptomes of 10 near isogenic lines (NIL), each with a unique Rps gene, and the recurrent susceptible parent ‘Williams’. A total of 4330 differentially expressed genes (DEGs) were identified in ‘Williams’ while 2075 to 5499 DEGs were identified in each NIL. Comparisons between the NILs and ‘Williams’ allowed classification of two major groups of DEGs of interest: incompatible reaction associated genes (IRAGs) and compatible reaction associated genes (CRAGs). Hierarchical cluster analysis divided NILs into three clusters: Cluster I (Rps1-a), Cluster II (Rps1-b, 1-c and 1-k) and Cluster III (Rps3-a, 3-b, 3-c, 4, 5, and 6). Heatmap analysis, along with GO analysis suggested that the diversity of clusters for NILs were likely due to variation of the number of DEGs and the intensity of gene expression, rather than functional differentiation. Further analysis suggested that transcription factors might play pivotal role in determination of the cluster pattern, and that WRKY family were strongly associated with incompatible reactions. Analysis of IRAGs and CRAGs with putative functions suggested that the regulation of many phytohormone signaling pathways were associated with incompatible or compatible interactions with potential crosstalk between each other. As such, our study provides an in depth view of both incompatible and compatible interactions between soybean and P. sojae, which provides further insight into the mechanisms involved in host-pathogen interactions. 22 samples were sequenced, 11 inoculated with P. sojae, the other 11 were mock-inoculated

Barley seed proteome analysis - Genes for seed longevity in barley identified by genomic analysis on near isogenic lines

Project description:Genes controlling differences in seed longevity between two barley (Hordeum vulgare) accessions were identified by combining a quantitative genetics approach with ˈomicsˈ technologies in Near Isogenic Lines (NILs). The NILs were derived from crosses between the spring barley landraces L94 from Ethiopia and Cebada Capa from Argentina, which produce short-lived and long-lived seeds, respectively. The NILs harbor introgressions from Cebada Capa in four QTLs for seed longevity on 1H and 2H in the background of L94. A label-free proteome analysis was performed on mature, non aged seeds of the two parental lines and the L94 NILs.
