Title |
Lodderomyces elongisporus Glucose Replicate 3 |
Sample type |
mixed |
|
|
Channel 1 |
Source name |
Lodderomyces elongisporus NRRL YB-4239 glucose
|
Organism |
Lodderomyces elongisporus NRRL YB-4239 |
Characteristics |
treatment: 2% glucose for 3 generations growth
|
Treatment protocol |
One culture was treated with 2% glucose for 3 generations growth; the other culture was treated with 2% xylose for 3 generations growth.
|
Growth protocol |
Lodderomyces elongisporus NRRL YB-4239 was grown aerobically at 30˚C for approximately 16 h in YPD (1% yeast extract, 2% peptone, 2% glucose) to early-log phase. Cells were washed once in YP (1% yeast extract, 2% peptone) and split into two cultures. Both cultures received the addition of sugar to a final concentration of 2%: glucose was added to one culture; xylose was added to the other culture. Cells were collected at OD600 0.5-0.6 after 3 generations aerobic growth at 30˚C.
|
Extracted molecule |
total RNA |
Extraction protocol |
Cell collection, lysis, and total RNA isolation were performed as previously described in Gasch, A. P. (2002) Methods Enzymol 350: 393-414. Following total RNA isolation, RNA was further purified with LiCl and RNeasy Mini kit (Qiagen). RNA concentration was determined by NanoDrop spectrophotometer (Thermo Scientific).
|
Label |
Cy5
|
Label protocol |
Sample labeling was performed as described in Gasch, A. P. (2002) Methods Enzymol 350: 393-414, using cyanine dyes (Amersham), Superscript III (Invitrogen), and amino-allyl-dUTP (Ambion). RNA collected from cells grown in each sugar condition was labeled with Cy5 dye and was directly compared to a genomic DNA reference sample labeled with Cy3 dye.

Hybridization protocol |
Arrays were hybridized in a NimbleGen hybridization system 12 (BioMicro) following the standard NimbleGen operating protocol. See www.nimblegen.com.
|
Scan protocol |
Arrays were scanned using a GenePix 4000B scanning laser (Molecular Devices) following the standard NimbleGen operating protocol. See www.nimblegen.com.

Description |
Biological replicate 3 of 3. Control glucose-grown cells, harvested after 3 generations.
|
Data processing |
Data normalization was performed using custom perl scripts and Bioconductor (Gentleman, R. C. et al. (2004) Genome Biol 5: R80). The affy() package (Gautier, L. et al. (2004) Bioinformatics 20: 307-315) was used to apply probe-level quantile normalization to the log2 signal of RNA versus the genomic DNA control (Cy5/Cy3). Gene-level expression changes were summarized with the median value of each probe set contained completely within each predicted ORF. See the included file LeloProbeMapping.txt for a mapping of probes to genes.
