Research Interests
  • The production of the variety for rice oil
    keyword : giant embryo, rice oil
    2010.06~2019.03.
  • Genetic regulation of the synthesis, intracellular transportation and accumulation of rice storage proteins
    keyword : Prolamin, Glutelin, Endoplasmic reticulum, Golgi apparatus, Protein storage vacuole, Protein body, Protein Trafic
    1996.04~2019.03Rice seed storage proteins mainly compose of prolamin and glutelin. Both storage proteins mRNA are sorted to each subdomain of the ER (Hamada, et al, 2003), and both proteins are synthesized on each ER membrane and translocated into the ER lumen. They are stored in morphologically distinct protein body (PB; Tanaka et al., 1980; Krishnan et al., 1986; Yamagata and Tanaka, 1986). Prolamins are stored as intracisternal inclusion granules within the ER lumen (PB-I), whereas glutelins are packaged in a protein storage vacuolar compartment (PSV), same as globulins in dicot (PB-II; Tanaka et al., 1980; Krishnan et al., 1986). The two types of storage compartment in a cell is characteristic in rice. But, the genetic mechanism in the cellular process of the accumulation into protein bodies of both proteins has not been known well. The goal of the rearch is to clear the genetic mechanism of the accumulation of storage proteins into protein bodies..
