Tobacco plants that are somatic mosaics for expression of a cytokinin-synthesizing gene have viviparous leaves. Such a formation of shoots in an abnormal position represents a significant deviation from the usual organization of the plant body where a central axis produces shoots only in the axils of lateral leaf appendages and according to a precise(More)
Plant sequences that act as transcriptional activation domains in yeast as well as in plants have been isolated by genetic selection in yeast. The selection was based on the reconstitution of a functional GAL4 transcriptional activator. Since the peptides show no homology with reported activation domains, they represent a new class of activating sequences.(More)
