Location of induced mutations and reversions in the chloroplast genome of Helianthus annuus

Location of induced mutations and reversions in the chloroplast genome of Helianthus annuus A chloroplast DNA mutation site associated with the ‘chlorina’ phenotype was identified in mutant lines en:chlorina-7 of Helianthus annuus. Following nitroso-methyl urea (NMU)-retreatment of the en:chlorina-7 mutant maternally inherited revertants in terms of leaf colour and plant vigour were obtained. Thorough restriction analysis revealed rearrangements in revertant (r-en:chlorina) cpDNA. The restoration of the original cpDNA pattern correlated with the correction of chlorophyll deficiency in green revertants. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Plant Growth Regulation Springer Journals

Abstract

A chloroplast DNA mutation site associated with the ‘chlorina’ phenotype was identified in mutant lines en:chlorina-7 of Helianthus annuus. Following nitroso-methyl urea (NMU)-retreatment of the en:chlorina-7 mutant maternally inherited revertants in terms of leaf colour and plant vigour were obtained. Thorough restriction analysis revealed rearrangements in revertant (r-en:chlorina) cpDNA. The restoration of the original cpDNA pattern correlated with the correction of chlorophyll deficiency in green revertants.
