Light and substrate regulation of nitrate reductase (NR) expression were
compared in wild type and mutant lines of Nicotiana plumbaginifolia.
Mutants affected in the NR structural gene (nia) or in the biosynthesis of
the NR molybdenum cofactor (cnx) were examined. nia mutants expressing a
defective apoenzyme, as well as cnx mutants, overexpressed NR mRNA, whereas
nia mutants devoid of detectable NR protein had reduced or undetectable NR
mRNA levels. Diurnal fluctuations of NR mRNA were specifically abolished in
nia and cnx mutants, suggesting that the integrity of NR catalytic activity
is required for the expression of diurnal oscillations. Unlike some fungal
mutants, the nia and cnx mutants examined retained nitrate inducibility of
NR expression. The possibility of autogenous control of NR expression in
higher plants is discussed.
