Abstract
The morphogenesis of animals is known to be controlled by homeotic genes, some of which encode proteins that contain a conserved domain: the homeobox.
Recently, it revealed that these homeobox containing genes exist also in plants.
To elucidate the mechanisms of morphogenesis of plants, we introduced the rice homeobox containing gene OSH1 under the control of three different promoters into tobacco and kiwifruit.
Transgenic tobacco introduced with OSH1 showed altered leaf phenotype, wrinkled, slender or tiny leaves, and became dwarf.
And it also showed morphological change in flowers with pale color and dissected margin.
Transgenic kiwifruit introduced with OSH1 also showed morphological changes with dissected leaf margin and showed dwarfism.
The correlation of gene expression and morphological change will be discussed.
