The plant vp1 gene encodes a transcription factor originally identified in maize that participates in the control of the transition from embryogenesis to seed germination. 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. This gene was mapped in sorghum using two well-studied inbred lines displaying contrasting PHS phenotypes. Linkage analysis revealed that the S. bicolor vp1 (Sbvp1) locus is linked to markers located on chromosomes 3 and 8 in maize. Analysis indicated that this gene is not correlated with PHS at a statistically significant level. Structural analysis of the Sbvp1 gene from both inbred lines showed a high degree of overall conservation (low polymorphism), even in the promoter region. These findings, taken together with the previously observed correlation between the pattern of expression of this gene and PHS performance, suggest that Sbvp1 might act downstream in the signalling pathway that leads to seed germination, or even be differentially regulated as a consequence rather than as a cause of the phenotypic behaviour.Key words: viviparous-1, Sbvp1, dormancy, quantitative trait loci (QTL), pre-harvest sprouting, genetic mapping.
