Nitrite reductase mutants as an approach to understanding nitrate assimilation in Chlamydomonas reinhardtii.

Plant physiology - 1 Jan 2000

Navarro M T, Guerra E, Fernández E, Galván A

Abstract excerpt

We constructed mutant strains lacking the nitrite reductase (NR) gene in Chlamydomonas reinhardtii. Two types of NR mutants were obtained, which either have or lack the high-affinity nitrate transporter (Nrt2;1, Nrt2;2, and Nar2) genes. None of these mutants overexpressed nitrate assimilation gene transcripts nor NR activity in nitrogen-free medium, in contrast to NR mutants. This finding confirms the previous...
