Affymetrix Rice Genome Array (rice)
Description
Reproductive barriers perform a vital role during speciation. Hybrid weakness, the poor development of hybrids compared to their parents, hinders gene exchange between different species at the postzygotic stage. The molecular and evolutionary mechanisms of hybrid weakness are poorly understood. Here, we report that two incompatible dominant loci (Hwi1 and Hwi2) involving three genes determine the high temperature-dependent expression of hybrid weakness in interspecific hybrids of rice. Hwi1 comprises two indispensable wild rice (Oryza rufipogon)-specific leucine-rich repeat receptor-like kinase (LRR-RLK) genes, 25L1 and 25L2, for inducing hybrid weakness, and the genes possibly undergo balancing selection. Hwi2, a rare allele that is predominantly distributed in indica rice (Oryza sativa), encodes a secreted putative subtilisin-like protease. Functional analysis indicated that pyramiding of Hwi1 and Hwi2 activates the autoimmune response in the basal nodes of hybrids, interrupting root formation and then impairing shoot growth, likely due to immune signal is transmitted from the basal nodes to the above-ground parts. Considering the nature of RLK activity of Hwi1 and the protease activity of Hwi2, we propose that a certain endogenous signaling molecule produced by Hwi2 is perceived by Hwi1 to activate autoimmunity through ligand-receptor signal transduction. These findings bring new insights into our understanding of reproductive isolation and may benefit rice breeding to maximally utilize invaluable genes from wild rice.

- Affymetrix Chicken Genome Array (chicken)
Description
Genotype VIId NDV is characterized by severe tissue damage in chicken lymphoid organs compared to other virulent strains. However, biological basis of this unusual pathological phenotype is unknown. Host response is associated with pathogenicity of Newcastle Disease Virus (NDV). We aim to determine the contribution of host response to the severe tissue destruction in the lymphoid system caused by genotype VIId NDV.

- Affymetrix Chicken Genome Array (chicken)
Description
Recently, a novel protein in the influenza virus segment 3 has been identified, namely PA-X. This small protein has been reported to play a role in modulating host response of the 1918 H1N1 pandemic virus-infected mice. However, poteinal role of this protein in the pathogenicity and regulating host response of the highly pathogenic H5N1 virus in a chicken animal model is completely unknown.

- Affymetrix Maize Genome Array (maize)
Description
The expression profiling of a newly identified maize dwarf mutant Dwarf11 (D11) was investigated by Affymetrix array. Results showed that transcripts encoding GA biosynthetic and catabolic enzymes ent-kaurenoic acid oxidase (KAO), GA 20-oxidase (GA20ox), and GA 2-oxidase (GA2ox) were up-regulated in the D11 mutant.
