  • Elucidating the mechanism of recognition and evasion in viral infection of tomato
    ~ Towards the development of new anti-viral agent ~

    The structural basis in which the virus resistance protein found in wild tomato binds with the tomato mosaic virus protein to inhibit its propagation has been clarified. The virus resistance protein of tomato and the tomato mosaic virus protein each undergoes repetitive changes resulting in the host recognition of the viral molecule, viral adaptive evasion of the recognition, host counteradaptation, and viral response to counteradaptation. Such information on the structural basis of recognition and evasion could be used in developing an efficient plant anti-viral agent that can be expected to control the spread of viral diseases and an increase in the yield of affected crops.

  • Successful production of silk fibers with unnatural amino acids
    ~ Towards potential medical applications of new silk materials ~

    Silk fibers containing unnatural amino acids were successfully produced for the first time by simply feeding transgenic silkworms with a diet supplemented with the amino acids. The fluorescent molecules were successfully bound to the silk fibers of transgenic silkworm by using the introduced unnatural amino acids as selective reaction sites. This result suggests a potential binding ability that could be used with various molecules as well. It is expected that incorporating biologically active substances such as bone morphogenetic protein etc. could pave the way for the development of silk materials with wide applications in regenerative medicine.

  • Genetic blueprint of the wheat genome revealed
    ~ Towards accelerating the development of new cultivars ~

    The International Wheat Genome Sequencing Consortium (IWGSC), which includes the NIAS, has successfully decoded the draft sequence of the wheat genome and characterized approximately 120,000 genes that comprise the genome. The draft genome sequence of wheat which is 40 times the size of the rice genome will provide new insights into identifying the function of wheat genes, cloning of genes for agronomically important traits, and the development of DNA markers to accelerate the breeding of cultivars with improved traits in terms of yield, grain quality and resistance to biotic/abiotic stresses.

  • World’s first production of piglets from cryopreserved oocytes

    Live piglets were successfully produced for the first time from immature oocytes vitrified and cryopreserved at sub-zero temperatures. By adjusting the optimum warming temperature of cryopreserved oocytes and subjecting the process of in vitro embryo production, the percentage of survival increased to 20% and the success rate of embryo development into the blastocyst stage increased by 1.6 fold. This defined system for in vitro embryo production will facilitate a more efficient and stable preservation of pig genetic resources.

  • Discovery of synergistic insecticidal effect of calcium oxalate crystals and protease

    The needle-shaped calcium oxalate crystals called raphides commonly found in tissues of many plants such as kiwifruits etc. has been shown to exhibit extremely strong synergistic defensive properties against harmful herbivorous insects in the presence of cysteine protease. The synergistic defensive effect of raphides with other defensive factors could be used in developing cultivars with strong defensive properties among crops such as taro and grapes with low expression of cysteine protease, and is expected to pave the way for further development of safer and more effective insecticide technology.

  • Development of a database to maximize the utilization of large-scale data on agrigenomics

    A database infrastructure has been developed that will allow easy access to large-scale genome data derived from agriculturally important organisms and lead to more efficient utilization of such information in agricultural productivity. The Agrigenomics Information Database (AgrID, http://agrid.dna.affrc.go.jp/) was designed to facilitate users to perform analysis of genomic data by computers equipped with large-scale data processing capacity. This will therefore serve as a valuable resource for advancement of research in genomics and play an important role in more efficient utilization of genomics data for crop improvement particularly in accelerating the breeding of new varieties.
