WebAmong them is AtCKX6, a gene encoding a cytokinin oxidase involved in cytokinin breakdown (Werner et al. 2003), which is rapidly and transiently induced by auxin (Redman et al. 2004). Interestingly, the AtCKX6 gene is also down-regulated by NPA, indicating that AtCKX6 gene expression may depend on translocated auxin (Werner et al. 2006).
