The role of GAs in promoting seed germination is well known and experiments with seeds from different species have suggested the requirement of de novo synthesis of GAs upon imbibition for germination. There are also strong indications that the enhancement of GA synthesis is part of the mechanism through which environmental signals (i.e.

Different lines of evidence suggest that vp1 participates in preharvest sprouting (PHS) resistance in cereals, but the genetic relationship is not yet established. Thus, the aim of this study was to investigate if there is a connection between vp1 and the formerly documented quantitative trait loci for PHS in Sorghum bicolor.
