A mutation in At-nMat1a, which encodes a nuclear gene having high similarity to group II intron maturase, causes impaired splicing of mitochondrial NAD4 transcript and altered carbon metabolism in Arabidopsis thaliana.

Abstract excerpt

To elucidate the mechanism of cellulose synthesis, we isolated a mutant of Arabidopsis (changed sensitivity to cellulose synthesis inhibitors 1, css1) that showed changed sensitivity to cellulose biosynthesis inhibitor. The analysis of phenotypes indicated that the css1 mutation influenced various fundamental metabolic pathways including amino acid metabolism, triacylglycerol degradation and polysaccharide...
