Sample GSM431926 Query DataSets for GSM431926
Status Public on Jul 22, 2009
Title Root- +Fe+P biological rep2
Sample type RNA
Source name Root segments derived from 11-d-old rice (Oryza sativa) seedlings under +Fe+P conditions
Organism Oryza sativa
Characteristics tissue: Root
Treatment protocol For –Fe+P treatment, FeCl3 and citric acid were removed. For +Fe-P treatment, NaH2PO4 was removed. While for –Fe–P treatment, FeCl3, citric acid, and NaH2PO4 were removed.
Growth protocol Rice seeds were germinated in distilled water for 2 d. After germination, 25 seedlings were transferred to a plastic net floating on the Yoshida nutrient solution (Yoshida et al., 1976).
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using RNAzol (Campro Scientific) and glass beads according to the manufacturer’s instructions.
Label biotin
Label protocol The One-Cycle Target Labeling and Control Reagent kit (Affymetrix 900493) and the protocols optimized by Affymetrix were used to prepare biotinylated complementaryRNA (cRNA; from 5 mg of total RNA) for microarray hybridization (n = 2 per group).
Hybridization protocol Microarray analysis was carried out using an Affymetrix technology platform and Affymetrix GeneChip rice genome array. Briefly, fragmented cRNA was mixed with spiked controls and applied to Affymetrix Test chips, and good quality samples were then used to hybridize with the rice GeneChip. The hybridization, probe array washing and staining, and washing procedures were executed as described in the Affymetrix protocols.
Scan protocol Probe arrays were scanned with a Hewlett-Packard Gene Array Scanner (Leiden Genome Technology Center).
Description Gene expression data from 10-d-old rice (Oryza sativa) seedlings under +Fe+P conditions
Data processing Data analysis was carried out using Avadis 4.3 (Strand Genomics) and Partek Genomics suite software, version 6.3. Raw intensity data were initially normalized using the MAS5 algorithm, which allowed probe identifier present calls to be determined.
