Provided are trnasgenic plants comprising cells transformed or transfected with a recombinant DNA construct containing a coding sequence which encodes phytochrome A, which when expressed, causes the stimulation of phytochrome A and confers upon said plant the ability to undergo proximity-conctitional dwarfing Also provided are a recombinant DNA construct containing a coding sequence encoding phytochrome A, which when expressed, is effective in conferring the trait of proximity-conditional dwarfing on plants comprising cells transformed ar tansfected with this construct, a method for conferring proximity-conditional dwarfing upon plants, transgenic plants produced by this method, and seeds obtained by growing such plants. |
