Dry seed transcriptome differences associated with relief of sly1-2 seed dormancy through after-ripening or overexpression of the gibberellin-receptor GID1b

ABSTRACT: Plant embryos can survive years in a desiccated, quiescent state within seeds. In many species, seeds are dormant and unable to germinate at maturity. They acquire the capacity to germinate through a period of dry storage called after-ripening (AR), a biological process that occurs at 5-15% moisture when most metabolic processes cease. Because stored transcripts will be among the first proteins translated upon water uptake, they likely impact germination potential. Transcriptome changes associated with the increased seed dormancy of the GA-insensitive sly1-2 mutant, and with dormancy loss through sly1-2 after-ripening or constitutive overexpression of the GA receptor (GID1b) were characterized in dry seeds. This experiment used the same seed batches as a previous experim
