Several recombinat viruses of porcine circovirus type 2 (PCV2),including P1, P2, ZJ-R, VL258, and VL264, have been found. The PK15 cells were transfected by the molecular clones of the abovementioned viruses, where specific sets of genes are up-regulated or down-regulated.
Publication Title

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Ectromelia virus (ECTV) has emerged as a valuable model for investigating the host-orthopoxvirus relationship as it relates to pathogenesis and the immune response. We analyzed the transcriptional signatures of BALB/3T3 cells at different times after infection with Ectromelia virus. Mouse Genome 430 2.0 arrays were used to analyze global changes in gene transcripts to generate a pool of genes that was a fold change cut-off of 1.5 or 0.5 in infected samples versus non-infected samples.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Ectromelia virus (ECTV) has emerged as a valuable model for investigating the host-orthopoxvirus relationship as it relates to pathogenesis and the immune response. ECTV causes mousepox in most strains of mice, including BALB/c and DBA/2, and these are therefore classified as susceptible mice. Conversely, C57BL/6 and certain 129 strains display limited pathology and a very low mortality, and are thus classified as resistant. To understand the host genetic factors of different mouse strains in response to ECTV infection, we carried out a microarray analysis using Affymetrix Gene-Chip Mouse Genome Arrays of spleen tissues from BALB/c and C57BL/6 mice at 3 and 10 days post-ECTV infection.

- Affymetrix Maize Genome Array (maize)
Description
To understand the transcriptome changes during drought tolerance in maize, the drought-tolerant line Han21 and drought-sensitive line Ye478, which show substantial differences in drought tolerance at the seedling stage, were selected for this study. Using the GeneChip Maize Genome Arrays, we applied genome-wide gene expression analysis to the two genotypes under gradual drought stress and re-watering. We identified 2172 common regulated transcripts in both lines under drought stress, with 1084 common up-regulated transcripts and 1088 common down-regulated transcripts. Among the 2172 transcripts, 58 potential protein kinases and 117 potential transcription factors were identified. The potential components of the ABA signaling pathway were identified from the common regulated transcripts. We also identified 940 differentially regulated transcripts between the two lines. Among the 940 transcripts, the differential expression levels of 29 transporters and 15 cell wall-related transcripts may contribute to the different tolerances of the two lines. Additionally, we found that the drought-responsive genes in the tolerant Han21 line recovered more quickly when the seedlings were re-watered, and 311 transcripts in the tolerant Han21 line were exclusively up-regulated at the re-watering stage compared to the control and stress conditions. Our study provides a global characterization of two maize inbred lines during drought stress and re-watering and will be valuable for further study of the molecular mechanisms of drought tolerance in maize.

Description
Previously, we successfully introduce the bacterial blight resistance trait from Oryza meyeriana into O. sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a progeny named Y73 was generated with recurrent parent O. sativa L. ssp. japonica cv. Dalixiang, and it shows high resistance to broad-spectrum of bacterial blight pathogens Xanthomonas oryzae pv. Oryzae (Xoo). However, the resistance mechanism of Y73 is remain undiscovered. To provide insights into the high resistance phenotype of these plants, we examined the transcriptome response in leaves of Y73 to the bacterial blight infection in this study. Xoo inoculated and mock inoculated rice plants were grown in growth room and the global analysis of gene expression events in rice leaves at 24 hours post inoculation (hpi) were analyzed using Affymetrix Rice GeneChip microarrays.

Description
We identified and characterized a rice epigenetic mutant Epi-df which exhibits a dwarf stature and various floral defects that are inherited in a dominant fashion. We demonstrated that Epi-df participates in Polycomb repressive complex 2 (PRC2) mediated gene silencing. Epigenetic mutations results in ectopic expression of Epi-df and pleiotropic developmental defects in mutant plants. Moreover, ectopic expression of Epi-df leads to mis-regulated H3K27me3 and changed expression of hundreds of genes involved in a wide range of biological processes.

Description
Glyphosate (GLY) is an effective antimetabolite that acts against the shikimate pathway 5-enolpyruvylshikimate 3-phosphate (EPSP) synthase, However, little is known about the genome-scale transcriptional responses of bacteria after glyphosate shock. To investigate further the mechanisms by which E. coli response to a glyphosate shock, a DNA-based microarray was used for transcriptional analysis of E. coli exposed to 200 mM glyphosate.
