Marziani] Abstract : MADS box genes are implicated in different steps of plant development. Some of them are expressed in vegetative organs. Most of them, however, are expressed in flower tissues and are involved in different phases of flower development. Here we describe the isolation and characterization of an Asparagus officinalis MADS box gene, AOM1. The deduced AOM1 protein shows the highest degree of similarity with FBP2 of Petunia hybrida and AGL9 (SEP3), AGL2 (SEP1) and AGL4 (SEP2) of Arabidopsis thaliana. In situ hybridization analyses, however, show that the expression profile of AOM1 is different from that of these genes: AOM1 is expressed not only in flower organs but also in inflorescence and flower meristems. These data indicate a possible function of AOM1 during flower development as well as in earlier stages of the flowering process. Asparagus officinalis is a dioecious species which bears male and female flowers on different individuals. AOM1, which is expressed very early during the process of flowering and has a similar expression profile in male and female flowers, does not seems to be involved in asparagus sex differentiation.
