Antipodal transcriptional changes in Arabidopsis and Aethionema of key hormone regulatory genes. Summary of light-regulated changes in transcript levels in seeds, based on published data for Arabidopsis (after Stawska and Oracz 2015) and with the data for Aethionema presented in this study. Blue boxes indicate proteins whose stability is regulated by light. Black boxes indicate genes whose expression is light-regulated. Changes in expression upon light exposure are indicated by black (Arabidopsis), purple (Aethionema, both accessions), and orange (Aethionema, CYP accession only) arrows. The role of other photoreceptors in Aethionema seed germination is not yet known. As indicated by question marks, the stability of PIL5 and DELLA proteins is unknown in Aethionema.
