1.14.13.81 additional information identification of a xantha-l mutant, defective in a gene of Mg-protoporphyrin monomethyl ester cyclase, the mutant does not show the gun mutant phenotype, that is defective in the chloroplast-to-nucleus signal transduction and expresses Lhc even when chloroplast development is inhibited by the herbicide norflurazon, the xantha-181 mutant can synthesize Mg-protoporphyrin IX and Mg-protoporphyrin IX monomethyl ester, phenotype, overview Hordeum vulgare
