  The GeneChip Medicago Genome Array is designed specifically to monitor gene expression in Medicago truncatula, Medicago sativa, and the symbiotic organism Sinorhizobium meliloti. The Medicago Genome Array is particularly useful for agriculture researchers studying legume genomics and symbiotic relationships between nitrogen fixing bacteria and plants.
  Sequence information for this array was selected from data sources including the TIGR M. truncatula gene index (The Institute for Genomic Research, January 2005), gene predictions from the International Medicago Genome Annotation Group (IMGAG), gene predictions from the S. meliloti genome, and M. sativa EST information made available by TIGR. The array contains over 61,200 probe sets: 32,167 M. truncatula EST/mRNA-based and chloroplast gene-based probe sets; 18,733 M. truncatula IMGAG and phase 2/3 BAC prediction-based probe sets; 1,896 M. sativa EST/mRNA-based probe sets; and 8,305 S. meliloti gene prediction-based probe sets.
