Description: | Seed dormancy controls the start of a plant's life cycle by preventing germination of a viable seed in an unfavorable season. The molecular mechanisms controlling seed dormancy are not well understood. DELAY OF GERMINATION 1 (DOG1) has been identified as a major Quantitative Trait Locus (QTL) for seed dormancy in a Recombinant Inbred Line (RIL) population between the lowly dormant accession Landsberg erecta (Ler) and the high dormant accession Cape Verde Islands (Cvi) (Alonso Blanco et al., 2003). DOG1 is a key regulator of seed dormancy because dog1 mutants are completely non-dormant and do not show any obvious pleiotropic phenotypes, apart from a reduced seed longevity (Bentsink et al., 2006). We compared the transcriptome of dog1-1 mutant with that of its wild-type background NIL DOG1_Cvi on siliques at mid-maturation phase when DOG1 is highly expressed. This analysis shows the influence of DOG1 on gene expression related to dormancy induction during seed maturation. |
