Isolation and characterization of Nicotiana plumbaginifolia nitrate reductase-deficient mutants: genetic and biochemical analysis of the NIA complementation group

Abstract

Two hundred and eleven nitrate reductase-deficient mutants (NR−) were isolated from mutagenized Nicotiana plumbaginifolia protoplast cultures by chlorate selection and regenerated into plant. More than 40% of these clones were classified as cnx and presumed to be affected in the biosynthesis of the molybdenum cofactor, the remaining clones being classified… (More)
