  1. Maleck et al. [7] studied 10,000 EST clones obtained from the Arabidopsis Biological Resource Center representing approximately 7,000 genes. Schenk et al. [17] studied a custom array containing 2,375 ESTs with a biased representation of putative defense-associated and regulatory genes. From our estimate of redundancy (approximately 30%), this array contains 1,662 distinct genes. The study of Cheong et al. [48] involved the Affymetrix Arabidopsis Genome GeneChip array representing 8,200 genes. Desikan et al. [18] studied Arabidopsis Functional Genomics Consortium microarrays containing 11,000 EST clones representing approximately 7,800 distinct genes. The custom array of Swidzinski et al. [49] contained 75 ESTs previously implicated in programmed cell-death responses such as senescence and hypersensitive response.
