Rice (Oryza sativa) is the most important staple crop in Korea. With its small genome size of 389Mb, rice is a model plant for genome research. We analyzed expressed sequence tag (EST) clones from immature seeds of rice (cv. Ilpum) at 20 days after heading. The 25,668 EST clones were clustered by using SeqMan program and 7,509 clones were selected as unique clones. We compared the 7,509 unique genes with KOME database including the 32,127 FL-cDNA in rice. Finally, 4,990 clones were homologous and 2,519 clones non-homologous to FL-cDNA clones. In addition, we mapped the 7,509 cDNA clones by using TIGR rice pseudomolecule version 5. Ultimately, 7,347 clones were matched to be significant clones related to the TIGR rice pseudomolecules, but 162 clones were unmapped. For the clustering of orthologous group genes, we further analyzed the 7,509 EST clones from immature seeds using NCBI clusters of orthologous groups database. Among the clones, 4,968 clones were categorized into information storage and processing, cellular processes and signaling, metabolism and poorly characterized genes, proportioning 799 (14.89%), 1,536 (28.3%), 1,148 (21.2%) and 1,936 (35.7%) clones to the previous four categories, respectively. |
