Sample GSM301555 Query DataSets for GSM301555
Status Public on Jul 01, 2008
Title Control leaf (4)
Sample type RNA
 
Source name Sugarcane (Saccharum spp. hybrids) leaf tissue
Organism Saccharum hybrid cultivar N19
Characteristics Hybrid cultivar N19
Biomaterial provider South African Sugarcane Research Institute (SASRI)
Treatment protocol Cold-girdles were attached to sugarcane leaves (n=4) for a period of 56 h prior to harvest. The girdle consisted of 0.75 cm (diameter) soft plastic tubing, firmly clamped around each leaf, approximately 30 cm from the leaf base. Cooled water maintained at 5oC was then pumped through the tubing using a Grant LTD6G cooling bath (Grant Instruments, Barrington, Cambridge, UK). At harvest, leaf samples were immediately frozen in liquid nitrogen (–196oC) and subsequently milled in an A11 Basic Analysis Mill (IKA, Staufen, Germany). Ground leaf tissue was stored at –80oC in 50 ml centrifuge tubes prior to analysis.
Growth protocol Twelve month-old field grown Saccharum spp. (L.) hybrid cv. N19 (N19) cultivated at Mount Edgecombe, KwaZulu-Natal (SASRI) were used in the study, which was conducted in November, 2006. Plants were grown on a 5 x 15 m plot located on a north-east facing slope with a gradient of ca. 10o.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted using the extraction protocol of Bugos et al. (1995). Total RNA was checked for quality and integrity using a Bioanalyser 2100 and the NanoChip protocol according to the manufacturer’s directions (Agilent Technologies, Palo Alto, CA, USA). Labelled target used in hybridisations was generated from 15 μg of total RNA using the One-Cycle Eukaryotic Target Labeling Assay.
Label biotin
Label protocol All labelling, hybridizations of biotinylated cRNA to the GeneChip Sugarcane Genome Arrays (Affymetrix, Inc., Santa Clara, CA, USA) and data collection were performed by the Australian Genome Research Facility (AGRF, Melbourne, VIC, Australia).
 
Hybridization protocol All labelling, hybridizations of biotinylated cRNA to the GeneChip Sugarcane Genome Arrays (Affymetrix, Inc., Santa Clara, CA, USA) and data collection were performed by the Australian Genome Research Facility (AGRF, Melbourne, VIC, Australia).
Scan protocol The scanner operating software, GCOS, converted the signal on each array into a DAT file, which was then used to generate CEL and CHP files for analysis (Casu et al., 2007).
Description N/A
Data processing GeneSpring 7.3 (Agilent Technologies) was used for data analysis.
