Effects of inhibitors for signaling components on the expression of the genes for nitrate reductase and nitrite reductase in excised barley leaves

Abstract

Abstract Nitrate-induced accumulation of mRNAs for nitrate reductase and nitrite reductase was strongly inhibited by treatment with inhibitors of Ca2+ channels, protein phosphatases, and tyrosine protein kinases in excised barley leaves. It was shown that these components may be involved in the nitrate-response signaling pathways for the expression of nitrate and nitrite reductase genes in barley leaves.
