Identification of Gene Modules Associated with Low Temperatures Response in Bambara Groundnut by Network Based Analysis

PLoS One
PMCID: 4747569
PMID: 26859686
DOI: 10.1371/journal.pone.0148771

[…] atives such as comprehensive RNA sequencing—while becoming more affordable—can still be costly, prohibiting routine large-scale experiments. One possible solution for this problem is a cross-species (Xspecies) microarray approach [], involving the hybridisation between the cRNA of the species of interest and a closely related species for which a custom microarray chip is available. This approach h […]


Diversity in global gene expression and morphology across a watercress (Nasturtium officinale R. Br.) germplasm collection: first steps to breeding

PMCID: 4591680
PMID: 26504575
DOI: 10.1038/hortres.2015.29

[…] protcol adapted from Doyle.Hybridisation to X species chip. DNA from the control line (C) was sent to the National Arabidopsis Stock Centre (NASC) for hybridisation to the X species ATH1 genome array.Xspecies chip analysis – creation of probe mask (.cdf) files. Oligonucleotide GeneChip probes with low/no hybridisation to watercress transcripts were removed using the gDNA probe masking strategy dev […]


DNA microarray global gene expression analysis of influenza virus infected chicken and duck cells

Genom Data
PMCID: 4535746
PMID: 26484178
DOI: 10.1016/j.gdata.2015.03.004

[…] ities above an experimentally set threshold. Selection was performed using a cel file parser script written in the Perl programming language (X-species Version 2.1, http://affymetrix.arabidopsis.info/xspecies/). After installing Active Perl software for windows (Active Perl version for Windows), CDF_masking.zip was downloaded and unzipped to a chosen location on the computer (http://af […]


Maternal protein energy malnutrition during early pregnancy in sheep impacts the fetal ornithine cycle to reduce fetal kidney microvascular development

PMCID: 4216596
PMID: 25077559
DOI: 10.1096/fj.14-255364

[…] in which the perfect match (PM) probe has a gDNA hybridization intensity greater than the user-defined threshold and were selected using a .cel file parser script (http://affymetrix.arabidopsis.info/xspecies/), which produces a probe mask file (.cdf) compatible with a range of microarray analysis packages (e.g., Genespring; Agilent Technologies). Probe mask files (.cdf) were produced using gDNA h […]


Analysis of ripening related gene expression in papaya using an Arabidopsis based microarray

BMC Plant Biol
PMCID: 3562526
PMID: 23256600
DOI: 10.1186/1471-2229-12-242

[…] fruit []. Commercial oligo-chips are not currently available for these organisms and comprehensive RNA sequencing can still be costly often prohibiting routine experiments. However, a cross-species (XSpecies) microarray is an alternative approach that has been successfully used to study the transcriptomes of non-model organisms [,].Papaya is a member of family Caricaceae within the Brassicales, t […]


Geological Substrates Shape Tree Species and Trait Distributions in African Moist Forests

PLoS One
PMCID: 3419707
PMID: 22905127
DOI: 10.1371/journal.pone.0042381
call_split See protocol

[…] We investigated the main axes of variation in species composition and underlying patterns of species distribution with correspondence analysis (CA) of the plots (n = 56,445)×species (n = 31) abundance matrix. CA, also known as reciprocal averaging, produces a simultaneous ordination of plots and species . It is a robust method for identifying compositional gradients with […]
