Homoeologous segments of the genomes of rice and Arabidopsis had been identified previously by hybridization- based approach. Using genome sequence data of Arabidopsis and rice, we were able to identify regions with clustered lipase genes. There were ten lipase genes clustered in one Arabisopsis BAC sequences. We also found out ten lipase genes present in a single rice PAC clone. There are seven lipase genes clustered in other rice BAC clones, too. Most of these lipase genes contained five exons, with conserved intron sites. Phylogenic relationship and gene expression patterns of these lipase genes were studied. Comparative analysis of the organization in nearby regions of both genome were also carried out.
