The GeneChip™ Maize Genome Array contains probe sets to detect transcripts from Zea mays, one of the most economically important crops in the world. The GeneChip Maize Genome Array, through examination of gene expression patterns of Zea mays, will enable researches to view the global transcription effects of external stimuli, such as fertilizers, pesticides, and growth conditions.

• The GeneChip Maize Genome Array provides comprehensive coverage of over 100 cultivars present in NCBI's UniGene data set, including the most highly represented strains: B73, Ohio43, W22, W23, W64A, and Black Mexican Sweet.
• The Maize Genome Array has 17,555 probe sets to interrogate approximately 14,850 Zea mays transcripts, which represent 13,339 genes (12,113 of which are represented in distinct UniGene clusters).
• Use the Power of the Probe Set and get multiple independent measurements for each transcript that delivers the greatest accuracy and reproducibility of any microarray platform.
• GeneChip System: richer data, sharper insights, better decisions.

Array Profile
The sequence information for this array was selected from NCBI's GenBank™ (up to September 29, 2004) and Zea mays UniGene Build 42 (July 23, 2004) databases. Probe sets on the array include 15 oligonucleotide pairs to detect each transcript, for added robustness and to facilitate detection of polymorphisms.

The Maize Genome Array was created within the GeneChip Consortia Program.
