The regulation of the expression of the A. nidulans niiA and niaD genes (encoding nitrite reductase and nitrate reductase activities, respectively) was investigated by Northern blotting. It was demonstrated that expression of the niiA and niaD genes is controlled at the level of mRNA accumulation an

## Summary The effect of constitutive expression of nitrate reductase (NR) on the regulation pattern of nitrite and nitrate transporters (NT) has been analysed in __Chlamydomonas reinhardtii__. Strain Tx11‐8, bearing the chimeric __Nia1__ gene for NR under the control of the __cabll‐1__ gene promot
In leaves of Phaseolus vulgaris L. ev. Prelude, the light-induced increase in activity of NADH-nitrate oxidoreductase (E.C.1.6.6.2; NAR) and reduced benzylviologennitrite oxidoreductase (E.C.1.6.6.4; NIle) starts at a certain stage in the development of the chloroplasts. In leaves with completely de
