rsr1-1 is early flowering and has an altered root morphology. (A) Under short-day conditions rsr1-1 plants started flowering much earlier than the parental line Pat(B33)-Gus. (B) Under long-day conditions, rsr1-1 plants formed fewer primary rosette leaves than Pat(B33)-Gus. In (A,B) the values presented are the mean ± SD of ≥15 plants. (C) In sterile culture on MS-medium with 60 mM Suc, rsr1-1 mutants maintained the early flowering phenotype and produced roots nearly twice as long as those of Pat(B33)-Gus. Under the same conditions, root hairs were shorter in rsr1-1 (D) than in Pat(B33)-Gus (E) and slightly irregular in shape.
