We have isolated seven allelic recessive Arabidopsis mutants, designated auperroot (sur 1.1 to sur 1.7), displaying several abnormalities reminiscent of auxin effects. These characteristics include small and epinastic cotyledons, an elongated hypocotyl in which the connection between the stele and cortical and epidermal cells disintegrates, the development of excess adventitious and lateral roots, a reduced number of leaves, and the absence of an inflorescence. When gerninated in the dark, sur 1 mutants dis not develop the apical hook characteristic of etiolated seedlings. We were able to phenocopy the Sur 1-phenotype by supplying auxin to wild-type seedlings, to propagate sur 1 explants on phytohormone-deficient medium, and to regenerate shoots from these explants by the addition of cytokinins alone to the culture medium. |
