    • Abstract


      A recessive EMS-induced mutation inherited in Mendelian fashion caused monocotyledonous embryo formation and seed germination on high salt medium inCatharanthus roseus. Availability during embryo development of exogenously supplied cytokinin kinetin suppressed the mutant phenotype. These observations suggest that, inC. roseus, (i) insufficiency in endogenous kinetin may lead to monocotyledonous embryo patterning and (ii) dicotyledonous embryo formation requires a critical amount of kinetin in certain cells of early embryos.
