Sample GSM1863616 Query DataSets for GSM1863616
Status Public on May 24, 2016
Title treatment cultivar 4 vs control cultivar 1 replicate 1
Sample type RNA
 
Channel 1
Source name Seedlings grown in climate chambers
Organism Zea mays
Characteristics variety: Codisco
treatment: cold-treated
tissue: primary root
age: 8 days post-germination
variety: Fergus
treatment: control
age: 8 days post-germination
Growth protocol In growth chambers: Control (18°C/16h, 12°C/6h, dark) - Cold treatment (12°C/16h, 6°C/8h, dark)
Extracted molecule total RNA
Extraction protocol Total RNA was extraced from roots with a Qiagen Rneasy© Plant Mini Kit
Label Cy5
Label protocol RNA samples were labelled with Cy3/Cy5 fluorophores by the manufacturer
 
Channel 2
Source name Seedlings grown in climate chambers
Organism Zea mays
Characteristics tissue: primary root
Growth protocol In growth chambers: Control (18°C/16h, 12°C/6h, dark) - Cold treatment (12°C/16h, 6°C/8h, dark)
Extracted molecule total RNA
Extraction protocol Total RNA was extraced from roots with a Qiagen Rneasy© Plant Mini Kit
Label Cy3
Label protocol RNA samples were labelled with Cy3/Cy5 fluorophores by the manufacturer
 
 
Hybridization protocol Hybridization was carried out according to a direct comparative loop design
Scan protocol Image acquisition was performed with a GenePix® scanner and quantified with the in-built software
Description Biological replicate 1 of 3. Treatment cultivar 4 was hybrized with the control cultivar 1 on the spotted oligo-array as a part of a microarray loop design.
Data processing Data were background corrected with the minimum method, print-tip lowess (within-array) normalized and scaled (between-array) from log2 of processed red signal/processed green signal
Quality check was performed with the MapMan Robin software. Data were processed and analysed with the web-based application CarmaWeb
Data Analysis: The normalized intensities within an array and between replicates were averaged to one single value per gene. Differentially expressed genes were determined with the limma paired moderate t-test. Adjusted p-values were generated according to the Benjamini and Hochberg (BH) method.
