Abstract
Many floral homeotic genes are expressed early in floral development and exhibit floral-specific expression, making them excellent candidates for use in engineering reproductively sterile plants. We have cloned and partially characterized Populus trichocarpa cDNAs and genes homologous to the Arabidopsis/Antirrhinum genes LEAFY (LFY)/ FLORICAULA (FLO), APETALA3 (AP3)/DEFICIENS (DEF), and AGAMOUS (AG)I PLENA (PLE). The P. trichocarpa LFY homolog, PtFL, shares 75% amino acid identity with LFY. PtD shows 81% amino acid similarity with DEF, and PtAG shows 85% homology withAG. PtFL is expressed in immature inflorescences on which floral primordia are developing. PtD is expressed strongly in stamen primordia from the onset of organogenesis, and is expressed at low levels in carpel primordia.
