Institute of Agrobiological Sciences, NARO

image The Institute of Agrobiological Sciences, NARO (NIAS) focuses on understanding the biological phenomena of agriculturally important plants, insects, microbes and animals to create innovative technologies, and eventually contribute to the solution of global issues such as food shortage due to rapid population growth and environmental problems due to climate change. NIAS is doing research and development to create new industries and new demands in the field of agricultural and medicinal industries by applying genetic engineering technologies to plants, insects and animals. In plants, for example, we are developing new rice varieties resistant to major diseases including blast. Moreover, we will include non-clinical and clinical research trials of rice-based edible vaccines for curing cedar pollinosis. In insects, we are developing medicinal materials from silk protein and medicines for humans and animals using transgenic silkworm. Furthermore, we are developing transgenic pigs to produce immune-deficit pigs and animal models for human diseases.

Prevention of pest damage for tomato by a natural substance

imageThe National Agriculture and Food Research Organization (NARO), has discovered that by the application of natural substance namely Loliolide to crops such as tomato, the damage caused by the important pests such as western flower thrips (Frankliniella occidentalis), two-spotted spider mite (Tetranychus urticae) could be suppressed. Loliolide doesn't has direct insecticidal effect, but it reduces the pest damage by means of enhancing the pest resistance in tomatoes etc. It is a promising material for pest control agents that utilizing the pest resistance of crops.Read more


Scientific elucidation of strength mechanism of bagworm silk, stronger than spider silk

image NARO in collaboration with a private company, has succeeded in collecting straight and long fiber of bagworm silk last year. Bagworm silk is found to be superior to spider silk, which was earlier said to be the strongest in naturally produced fibers, in aspects such as elasticity, fracture strength, and toughness. Hence bagworm silk is expected to its used as a new industrial fiber. In order to elucidate the strength mechanism of the bagworm silk, NARO and Toyota Institute of Technology has elaborately investigated the primary structure, secondary structure, and higher-order structure of silk proteins that are components of the bagworm silk. It was evident from the study that the strength of the bagworm silk was due to the highly ordered hierarchical structure of silk proteins. Read more


Elucidating the genome sequence of Japanese honey bee

imageThe Institute of Livestock and Grassland Science, NARO (NILGS) and Institute of Agro-biological Science (NIAS), in collaboration with the Tokyo University of Agriculture and Kyoto Sangyou University, has succeeded in deciphering the full genome sequence of the Japanese honey bee. Japanese honey bee has many useful properties including strong disease resistance as compared to the Western honey bee. Disease resistance of both honey bees can be analyzed at the genetic level by means of comparing the genome of the decoded Japanese honey bee with that of Western honey bee. This result will contribute to the development of more useful technologies for utilization of honey bees.Read more


A gene for sheath blight resistance that also increases seed size in rice

insect The Institute of Agrobiological Sciences, NARO (NIAS) has discovered that overexpression of BSR2 gene in rice conferred not only resistance against sheath blight and other diseases, but also produced longer seeds than wild type control plants. This result indicates that BSR2 is associated with disease resistance, growth rate and seed size in rice. In addition, it can be used to develop new control method for rice sheath blight disease and in increasing the flower size in plants. Read more.
