PLANT HORMONE MUTANTS OF ARABIDOPSIS THALIANA JAVED I. MIRZA Abstract: Mutant lines of Arabidopsis thaliana resistant to either spermine (a polyamine), naphthalene acetic acid (an auxin), or benzyl adenine (a cytokinin) were isolated by screening for growth of seedlings in the presence of growth inhibitory concentrations of the respective growth regulator. In addition to growth regulator resistance, mutant lines displayed distinct developmental phenotypes including alterations of the stature, seed dormancy, hypocotyls, roots, leaves, flowers and pods. Genetic evidence indicated that the mutant phenotype in 19 mutant lines was due to single recessive nuclear mutations. Institute of Biology, Bahauddin Zakariya University, Multan, Pakistan. |
