Abstract

To elucidate functions of tomato genes that have no homology with Arabidopsis genes, we analyzed expression profiles during fruit maturation. We prepared DNA array using 10,905 cDNA clones that were selected from fruit and leaf cDNA libraries of a miniature tomato cultivar Micro-Tom, as representatives of non-redundant sequences of 37,972 Micro-Tom ESTs. Tomato gene expressions in fruit developmental stages were monitored using the DNA array. Patterns of gene expressions were arranged into a 4x4 array using a self-organizing map algorithm. We identified 1151 probes corresponding to tomato genes that have no sequence homology with Arabidopsis genes, namely, non-Arabidopsis genes, on the DNA array. The expression patterns of the non-Arabidopsis genes distributed evenly in the self-organizing map, without significant differences with those of the whole genes. This result suggested that the non-Arabidopsis genes participate in diverse physiological processes of fruit maturation.
