The Arabidopsis fad7-1 mutant is deficient in the activity of plastid ω-3 desaturase as a direct consequence of being devoid of FAD7 mRNA. Comparison of the genomic sequence from the fad7-1 mutant line (JB101) with the wild-type sequence revealed that the only single-base pair transition occurred within the FAD7 gene-coding region. Transgenic study and northern analysis both indicated that the absence of FAD7 mRNA in the fad7-1 mutant was not caused by any disability regarding transcriptional regulation, but by the destabilization of the mRNA.
