National Institute of Agrobiological Sciences Successfully Controls Silkworm's Metamorphosis.Tokyo, Japan, Aug 4, 2005 - (JCNN JCNN - Japan Corporate News Network) - The National Institute of Agrobiological Sciences (NIAS Nias (nē`äs), volcanic island (1990 pop. 588,543), 1,842 sq mi (4,771 sq km), Indonesia, in the Indian Ocean, off Sumatra. Most of the population are descended from the Niah people; their economy is largely agricultural. The chief town is Gunungsitoli. Native handicraft is highly developed; megalithic shrines dot the land.) has succeeded in controlling the metamorphosis fatty metamorphosis fatty change. met·a·mor·pho·sis (m  t  -môr of silkworms silkworm, name for the larva of various species of moths, indigenous to Asia and Africa but now domesticated and raised for silk production throughout most of the temperate zone. The culture of silkworms is called sericulture. The various species of silkworms raised today are distinguished by the quality of the silk they produce, the type of leaves on which they feed, and the number of breedings per year.. NIAS has developed a technique to produce genetically-modified silkworms using the silkworm genome information that it decoded last year. Based on the new technique, NIAS has induced precocious pre·coc  ity (-k s -t metamorphosis of silkworms by excessively producing juvenile hormone esterase esterase /es·ter·ase/ (es´ter-as) any enzyme which catalyzes the hydrolysis of an ester into its alcohol and acid.es·ter·ase ( s, a kind of hormone-degrading enzyme. NIAS expects that this achievement will lead to the development of innovative pesticides, which are insect-specific, selective and environmentally-friendly. Details of the achievement is available in the August 2 online version of Proceedings of the National Academy of Sciences (PNAS PNAS - Pensacola Naval Air Station PNAS - Philippine National Airsoft Society PNAS - Phosphate:Na + Symporter PNAS - Proceedings of the National Academy of Sciences) of the United States of America.
