Abstract excerpt
Seed dormancy (SD) is the primary genetic determinant of pre-harvest sprouting (PHS) resistance. However, the molecular mechanisms underlying SD remain incompletely understood. Here, we identified a wheat cytochrome P450 gene, TaCYP94-A1, that is expressed at significantly higher levels in weak-dormancy varieties than in strong-dormancy varieties. TaCYP94-A1 expression increased during SD release and decreased...
