Affymetrix Maize Genome Array (maize)
Description
Plant growth regulators (PGRs) were commonly used in practical farming to restrict plant height and control lodging. Ethephon has been reported to shorten the internodes elongation and increase the harvestable grain yield of maize. In the present study, we characterized that internodes phenotypic responses to ethephon treatment induced should due to ethylene released inhibited the longitudinal growth of cells and promoted its the lateral growth.

- Affymetrix Chicken Genome Array (chicken)
Description
Adaptation to hypoxia is a complicated and important physiological course for organisms, but the genetic mechanism underlying the adaptation is not fully understood yet. Tibetan Chicken (T), an indigenous chicken breed in China which inhabit in high areas with an altitude above 2,900 meters. Shouguang Chicken(S) and Dwarf Recessive White Chicken (DRW), two lowland chicken breeds, were used as control groups. The heart was the first functional organ to develop during the embryonic development. Furthermore, the heart is an efficient energy converter utilizing the most appropriate fuel for a given environment. Therefore, GeneChip Chicken Genome Array was employed to identify the differentially expressed genes in embryonic hearts of Tibetan Chicken and two lowland chicken breeds in both hypoxic and normoxic incubating environments with a genome wide profile.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
HUB2 had been previously identified as a H2B monoubiquitinating E3 ligase. Loss of HUB2 leads to a pleiotropic phenotype, including reduced seed dormancy, smaller plant size and early flowering. Microarray expression profiling was used to identify differentially expressed genes between hub2-3 mutant and wild-type Col seedlings.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Pollen germination, along with pollen tube growth, is an essential process for the reproduction of flowering plants. The germinating pollen with tip-growth characteristics provides an ideal model system for the study of cell growth and morphogenesis. As an essential step towards a detailed understanding of this important process, the objective of this study was to comprehensively analyze the transcriptome changes during pollen germination and pollen tube growth. Using Affymetrix Arabidopsis ATH1 Genome Arrays, this study is the first to show the changes in the transcriptome from desiccated mature pollen grains to hydrated pollen grains and then to pollen tubes of Arabidopsis thaliana. The number of expressed genes, either for total expressed genes or for specifically expressed genes, increased significantly from desiccated mature pollen to hydrated pollen and again to growing pollen tubes, which is consistent with the finding that pollen germination and tube growth was significantly inhibited in vitro by a transcriptional inhibitor. The results of GO analyses showed that expression of genes related to cell rescue, transcription, signal transduction and cellular transport were significantly changed, especially for up-regulation, during pollen germination and tube growth, respectively. In particular, genes of the CaM/CML, CHX and Hsp families showed the most significant changes during pollen germination and tube growth. These results demonstrate that the overall transcription of genes, both in the number of expressed genes and in the levels of transcription, was increased. Furthermore, the appearance of many novel transcripts during pollen germination as well as tube growth indicates that these newly expressed genes may function in this complex process.

- Affymetrix Porcine Genome Array (porcine)
Description
The male hypogonadism is closely associated with adipose tissue metabolism. Domestic pig has been a widely used experimental animal in biomedical research because of their similarity to humans in body size and other physiological/anatomical features. However, the transcriptional responses of pigs to male hypogonadism in subcutaneous adipose tissue remain unclear so far.

Description
Clenbuterol-HCL can greatly reduce fat deposition and increase skeletal muscle growth at high dosages. In order to advance our understanding of the fundamental molecular mechanisms, Genechips were used to study the differential gene expression profiles of liver tissues among the pigs with/without Clenbuterol-HCL. Differentially expressed genes identified will be the candidates for further investigations on the molecular mechanisms involved in Clenbuterol-HCL of exerting repartition effects on adipose and skeletal muscle tissue.
