Proposed model of the response of apple buds to 6-BA over the period of floral transition. Genes in red font indicate upregulation in 6-BA treated buds, while genes in green font indicate downregulation by 6-BA treated buds. Genes in grey font indicate that their expression level changed, but not significantly, in response to the 6-BA treatment. Cytokinin (CK) and sugar presented in a red background indicate that their levels increased in response to the 6-BA treatment. Gibberellins (GAs) and starch presented in a green background indicate that their levels decreased in response to the 6-BA treatment. → means promotion; means inhibition
