Transcriptome changes associated with relief of sly1-2 seed dormancy through after-ripening or overexpression of the gibberellin-receptor GID1b

ABSTRACT: Seed dormancy is the inability for seeds to germinate even under favorable conditions. In the Arabidopsis Landsberg erecta (Ler) ecotype, 2 weeks of dry storage, called after-ripening, is sufficient to relieve seed dormancy. Such seed is referred to as after-ripened (AR) and has a high rate of germination when imbibed. While widespread transcriptome changes have been previously observed with seed dormancy loss, this experiment was designed to characterize transcriptional changes associated with the increased seed dormancy and dormancy loss of the gibberellin (GA) hormone-insensitive sleepy1-2 (sly1-2) mutant. The SLY1 gene encodes the F-box subunit of an SCF E3 ubiquitin ligase needed for GA-triggered proteolysis of DELLA repressors of seed germinatio
