Polymorphism of DNA sequences of cryptochrome genes is not associated with the photoperiodic flowering of wild soybean along a latitudinal cline
Both cultivated soybean and its wild relative Glycine soja exhibit strong photoperiodic sensitivity at different latitudes. Recent studies have demonstrated that the blue light-absorbing cryptochrome gene, CRY1a,...
