Abstract: To better understand the molecular mechanisms controlling development of sexual characters in Cycas edentata, we attempted to clone genes expressed differentially in male or female reproductive organs. We report a novel gene, named Fortune-1 (Ft-1), with enhanced expression in male reproductive organs. The 593-base-pair Ft-1 cDNA is predicted to encode a 77-amino-acid protein, and exists as a single copy gene in the C. edentata genome. Ft-1 expression is enhanced in male cones, including the cone axis, microsporophylls and microsporangia, but is reduced in ovules and undetectable in megasporophylls. Ft-1 is also weakly detectable in leaves. In roots and stems of C. edentata, Ft-1 transcripts are undetectable. The secondary structure prediction and homology search of Ft-1 protein show that it has a helix-loop-helix motif, and is without any homologue in the database. © 2002 Elsevier Science Ireland Ltd.
