 ===Function===
 *''OsGI'',a ''GI'' ortholog, regulates flowering time in response to photoperiodic conditions. Mutations in this gene delay flowering in inductive SDs (short-days),whereas flowering is marginally induced under LDs(long-days).In comparison, over expression of ''OsGI'' in transgenic rice causes late flowering in both SDs and LDs.In addition, ''OsGI'' has function to regulate ''Hd1'', a gene that also shows circadian rhythm<ref name="ref1" />. ''Os-GI'' affects gene expression of approximately 75% of genes among 27,201 genes and is required for strong amplitudes and proper phase-setting of  global gene expression under natural field conditions<ref name="ref2" />.
-*The cDNA of ''OsGI'' firstly found in ''se5'' mutant that is completely photoperiod-insensitive, the expression patterns of rice and Arabidopsis ''GI'' gene are both photoperiodically regulated and are very similar under LD and SD conditions<ref name="ref3" />. [[File:Limeijia2.png‎|frame|'''Figure 1''' Possible roles of isolated genes in the photoperiodic regulation of flowering in rice, including ''OsGI'', may function to inhibit flowering under LD conditions.(from reference <ref name="ref3" />).]]''GI'' is required for phase-dependent ''CO''transcription through the interaction with FKF1, which leads to cycling DNA binding with one finger (CDF) degradation and consequent derepression of CO. In addition, it has been known that GI protein interacts with ZEITLUPE (ZTL) F-box protein to control the diurnal rhythm of TOC1 protein in regulation of the Arabidopsis circadian clock<ref name="ref4" />.

-*''Os-GI'' also has function to maintain bioactive GA level through the regulation of the GA-deactivating enzyme genes in rice, ''Os-GI'' represses major ''OsGA2ox'' genes in order to maintain a proper bioactive GA level, ''osgi-1'' plants showed a semi-dwarf phenotype with elevated ''OsGA2ox'' gene expression <ref name="ref4" /> .[[File:Limeijia1.png‎|frame|'''Figure 2''' WT rice and osgi-1 plants grown under natural field conditions and ''osgi-1'' plant exhibits Semi-dwarf phenotype(from reference <ref name="ref4" />).]]
