Abstract
We got genomic AFL clones (AFL1, AFL2 and AFL1a)from apple. AFL genes has been reported as orthologue of arabidopsis LEAFY. AFL1a has 0.8 kb insetional sequence at first intron of AFL1. The insertion has 9 bp direct repeat at the 5' and 3' end. each apple cultivar shows random distribution of AFL genes and their inheritance pattern was also random. Some cultivar has another homologues of AFL above mentioned. These results suggest that apple AFL genes work for the flower formation flexibly. Wild species and relatives of apple also have several AFL homologues, the multi AFL genes are not specific to cultivated apple and are common feature among this genus. The AFL1a gene is checked whether this gene cause flower induction by creating transgenic arabidopsis.
