title: [Spontaneous and induced nitrosomethylurea reversion of plastomic chlorophyll mutants of the sunflower Helianthus annuus L].
abstract: Spontaneous and induced revertants obtained from plastome chlorophyll mutants of sunflower were subjected to genetic analysis. The mechanism of reversion (nuclear suppression, plastid suppression, true reversion, or mitochondrial suppression) of the plastid mutation was shown to affect the degree of restoration of morphological and physiological traits of sunflower plants.
