For almost half of people in the world, rice is the main dietary source of carbohydrates and calories; it plays a particularly important role in diets in Asia and Africa. Due to the increase in human population, the production of rice needs is increasing every year to maintain a stable dietary source. However, rice productivity was decreased as a consequent of loss of paddy field or due to climate change such as drought, submerges, pest and disease. To overcome this problem, rice genomic research to enhance rice productivity and quality is needed. This project covered from sequenced, annotated of gene content, identified the sequence polymorphisms between different rice subspecies such as japonica and indica, comparative genomic between this two sub species, as well as integrated goals in functional genomics and applied genomics for food security. Several country contributions for this project such as IRGSP, is a consortium from several country; RGP in Japan, MSU-USA and BGI-RIS from China. There are many rice genome research results have been contributed to develop higher rice productivity and adapt to climate change. Through analysis of sequence genome, transcriptomic and proteomic several genes, such as sub1A has been characterize and used to developed new rice varieties tolerance to drought and submerge. Recently, integrated genomic and metabolomic researchs to enhance rice quality such as rice fragrance, health traits have been developed. By using functional genomic approach through analyze of SNP variation across rice cultivars has been used for identification of phytochemical diversity in cooked rice and combine with metabolomic approach can distinguish which rice varieties acts as immunomodulator for human health.
