RACK1A transcription was also induced by a fungal elicitor and by abscisic acid, jasmonate, and auxin.

Loss-of-function mutations in RACK1A confer defects in multiple developmental processes including seed germination, leaf production, and flowering. rack1a mutants displayed reduced sensitivity to gibberellin and brassinosteroid in seed germination, hypersensitivity to abscisic acid in seed germination and early seedling development, and hyposensitivity to auxin in adventitious and lateral root formation.

However, the phytohormone abscisic acid promoted the expression level of RACK after imbibition in the wild type as compared with d1 mutant.
These seven proteins included a receptor for activated C-kinase (RACK) and six rice embryo globulin-2 proteins (REG2).
