additional information construction of a insertional mutant fad7i (SALK_147096C) inactivation mutant of FAD7, analysis of the fatty acid composition of the fad7i mutant shows compensatory responses at the TA level as a result of inactivation of the FAD7 gene, absence of AtFAD7 transcript in the mutant. Contruction of a fad7/fad8 double knockout mutant. Given the strong reduction (70%) in 18:3 content observed in the fad7/fad8 double mutant, in mutant fad7i after disruption of the AtFAD7 gene, FAD8 enzymatic activity is able to maintain, at least partially (43.7%), the amount of 18:3 and to a much lesser extent that of 16:3 (23.2%) at 22°C. Mutant genotypes and phenotypes, overview. Temperature-dependent expression levels. Disruption of the AtFAD7 gene in the insertion mutant does not result in significant changes in the transcript levels of FAD7 Arabidopsis thaliana

General Information

General Information Comment Organism
malfunction leaf lipid analysis of the Arabidopsis omega-3 desaturase fad7 mutant line at growth temperature of 22°C, overview. Disruption of the AtFAD7 gene in fad7i mutant results in a reduction of TAs with an 18:3 content of 29.6% and an even more reduced content of 16:3 down to 2%. Mutant fad7i maintains 74% of 18:3 production with respect to wild-type Col-0 while only 23% of 16:3 synthesis is maintained in the mutant Arabidopsis thaliana
physiological function plastidial omega-3 desaturase FAD7 is a major contributor to trienoic fatty acid biosynthesis in the leaves of Arabidopsis thaliana plants. Differences in the mechanism controlling AtFAD7 and AtFAD8 gene expression at different temperatures, the function of both plastidial omega-3 desaturases is coordinated in a non-redundant manner Arabidopsis thaliana
