Status of Biotechnological Research in Forestry in Japan

Japan occupies a leading position in the field of biotechnology, expecially in the field of cytological engineering and microorganism engineering in the world today. The biotechnological researches are undertaken mainly by government research units, civil enterprises and universities. The research units under government are the leading body, with the scientific force of civil enterprises as major element, while some universities are asked to participate in the researches. Emphasis is placed on enhancing the basic research, encouraging civil institucs to be engaged in biotechnological exploitation and on strengthening international cooperation. Fruitful researches have been accomplished in the crown gall resistant poplar breeding through gene engineering, high quality pulp.species breeding, protoplasmic fusion of woody plants, tissue culture of the important tree species for afforestation such as Paulownia sp., Betula sp. and Larix sp., and the biological conversion of wastes of forest products and residues of farm crops through industrial fermentation. The author makes three recommendations concerning the biotechnological development in forestry in China:(1) emphasis on enhancing the basic research on biotechnology in forestry, expecially on the gene background of forest biogenetics, the mechanism of gene expression and regulation, and researches on cytobiology;(2) promoting the developcmnt of gene engineering and the enzyme engineering in the field of microorganism research by taking advantage of the superiority in tissue culture and haploid breeding in China;(3) giving full play to the potentialities of higher educational institutions in researches on the biotechnology in forestry.
