Abstract: A pair of degenerate p rimers were designed according to the conservative amino acid sequences to clone the ent-kaurene oxidase from strawberry, and obtained two different RT-PCR p roducts from the strawberry leaves and flowers respectively. These two segments have different nucleotide equences, and Southern blot detected 3 cop ies of target gene in the strawberry genome. So there are at least two different genes coding ent-kaurene oxidase to respond different development signals.
