J.  aA mutation altering auxin homeostasis and plant morphology in Arabidopsis.h[electronic resource]  c1995  aMany aspects of plant development are associated with changing concentrations of the phytohormone auxin. Several stages of root formation exhibit extreme sensitivities to exogenous auxin and are correlated with shifts in endogenous auxin concetrations. In an effort to elucidate mechanisms regulating development of adventitious roots, an ethyl methanesulfonate-mutagenized M2 population of Arabidopsis was screened for mutants altered in this process. A recessive nuclear mutant, rooty (rty), displayed extreme proliferation of roots, inhibition of shoot growth, and other alterations suggesting elevated responses to auxin or ethylene. Wild-type Arabidopsis seedlings grown on auxin-containinig media phenocopied rty, seedlings were partially rescued on cytokinin.  amutation  aplant growth  aplant morphology  aMutação  aPlanta  aCrescimento de planta  aMorfologia1 aSTIMART, D.
