Abstract: The present invention relates to a mutated nucleic acid sequence of a delta-12 oleate desaturase enzyme (FAD2)—encoding nucleic acid from a Cruciferae plant, wherein said mutated nucleic acid sequence comprises the non-conservative mutation of at least one nucleotide of at least one codon representing an amino acid selected from the group consisting of: —the amino acid at position 259 of the amino acid sequence of said FAD2, —the amino acid at position 216 of the amino acid sequence of said FAD2, —the amino acid at position 90 of the amino acid sequence of said FAD2, —the amino acid at position 116 of the amino acid sequence of said FAD2, —the amino acid at position 276 of the amino acid sequence of said FAD2.

Abstract: The present invention comprises a method for testing the accuracy and the reliability of a thermal unit of a thermal cycler or of an enclosure of a PCR thermal cycler thermally controlled by pulsed air, said thermal unit and enclosure thermally controlled by pulsed air comprising a plurality of locations for reaction mixture tubes, said method comprising the following steps: a) arranging a set of temperature-measuring sensors in locations for reaction mixture tubes selected in said thermal unit and enclosure thermally controlled by pulsed air, said temperature-measuring sensors comprising: (i) a reaction tube suited to the type of thermal unit tested, (ii) a selected volume of liquid at least partially filling said reaction tube, (iii) a thermal probe at least partially submerged in said liquid, and (iv) at least one means for linking said thermal probe to a means for receiving a signal generated by said thermal probe, ?said locations in which said temperature-measuring sensors are arranged being distri
