Annotated Information
Function
The d1 mutant, which is deficient for the heterotrimeric G-protein α subunit (G α ) gene of rice, shows dwarfi sm and sets small round seeds. Heterotrimeric G proteins, which are composed of α (G α ),β (G β ) and γ (G γ ) subunits, play a variety of roles in a wide range of physiological responses by transducing extracellular information to intracellular components. Heterotrimeric G proteins act as signal transducer between a receptor (G-protein-coupled receptors, GPCRs) and downstream effectors. G-protein signaling starts with a conformational change of the GPCR upon ligand perception.The GPCR is a guanine-nucleotide-exchange factor (GEF) and its activation by the ligand promotes the exchange of GDP for GTP in the associated G α subunit. Subsequently, this complex dissociates into a G α -GTP monomer and a G β γ dimer to regulate downstream effectors. Mammals have multiples of each of the > 20 G α , 5 G β and 11 G γgenes
Expression
The G α protein was expressed in all the organs . Previously, the expression of the Arabidopsis G α(GPA1) was investigated by immunohistochemistry using anti-Arabidopsis G α antibody ( Weiss et al. 1993 ) and it was shown that G α is present throughout all development stages and in all organs examined such as roots, fl oral stems, rosette leaves, cauline leaves, fl owers and seed pods, with the exception of mature seeds. The accumulation of G α in Arabidopsis was higher in immature than in mature organs. The fact that the rice and Arabidopsis G α s were accumulated in the developing organs, fi tted well the possibility that plant G α s are involved in the regulation of cell proliferation. The expression pattern of rice G α suggests that this is also the case in rice. It was shown by immunochemical analysis that in Arabidopsis, G α accumulates highly in the root meristems, the shoot apical meristems and the fl oral meristems. The differences in expression in the meristem region between rice and Arabidopsis may refl ect speciesspecifi c expression patterns. The expression of the promoter of the Arabidopsis G α gene (GPA1) has also been investigated using histochemical analysis of transgenic plants expressing the GPA1::GUS reporter gene.
