:
By contrast, in rice ( Oryza sativa ), a model short-day plant, two independent floral pathways Heading date 1 ( Hd1, a CO orthologue ) -dependent and Early heading date 1 (Ehd1) dependent pathways-control Hd3a ( an FT orthologue ) and flowering time
Itoh et al., Nat Genet 2010
:
Hd3a expression is induced by Ehd1 ( Early heading date 1 ) expression when blue light coincides with the morning phase set by OsGIGANTEA ( OsGI ) -dependent circadian clocks
