Structure, Organization, and Expression of OsDr1 and OsDrAp1.

(A) OsDr1 was compared with Dr1 from wheat (wDr1), Arabidopsis (aDr1; Kuromori and Yamamoto, 1994), soybean (sDr1), yeast (yDr1; Kim et al., 1997), human (hDr1; Inostroza et al., 1992), and Drosophila (dDr1; Willy et al., 2000).

(B) OsDrAp1 was compared with DrAp1 from maize (mDrAp1), yeast (yDrAp1; Kim et al., 1997), human (hDrAp1; Goppelt et al., 1996), and Drosophila (dDrAp1; Willy et al., 2000).

H-Fold, histone-fold domain; QE, glutamine- and glutamate-rich domain; QA, glutamine- and alanine-rich domain; QP, glutamine- and proline-rich domain; aa, amino acids; B, basic amino acid stretch; RG, arginine-glycine repeat; A1 and A2, acidic amino acid–rich domain 1 and 2, respectively; P, proline-rich domain.

(C) and (D) DNA gel blot analysis of the organization of OsDr1 (C) and OsDrAp1 (D) in the rice genome.

(E) RNA gel blot analysis of the expression of OsDr1 and OsDrAp1 in rice. R, root; S, sheath and stem; L, leaf; C, suspension cells.
