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.


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.

Discovery of a specific immunity mechanism in hemipteran stinkbug

insectThe Institute of Agrobiological Sciences, NARO (NIAS) has clarified a part of a new immunity mechanism in insects, which has not been identified before, using brown-winged green stink bug,Plautia stali. Generally, the immune system of insects starts functioning with the invasion of microorganism into the body. It has been clarified for the first time that the hemipteran stinkbug has a unique microbial recognition protein. This result may lead towards the development of new pest control technology exclusive for hemipterans.Read more

Discovery of salivary protein essential for feeding in green rice leafhopper

insect The Institute of Agrobiological Sciences, NARO (NIAS) has discovered that the salivary protein NcSP75 is essential for feeding from phloem sap in green rice leafhopper (Nephotettix cincticeps). Suppression of the expression of this gene induces inhibition of sucking from phloem, resulting in growth retardation of nymphs, and decreasing the number of eggs laid by the female. This protein could be used as a potential target in developing a biologically efficient technology to protect rice plants from the pest damage.Read more.
