additional information
-
 evolution pattern of fatty acids and triacylglycerols contents is similar to that of PEPc activity, suggesting that PEPc may be involved in fatty acid and triacylglycerol biosynthesis during seed maturation Brassica napus
additional information
-
 hybridol variety: PEPc activity does not exceed 5 micromol/h per gram of fresh weight during the first stages of maturation. It then highly increases to reach more than 30 micromol/h per gram of fresh weight Brassica napus
additional information
-
 pactol variety: evolution of PEPc activity shows a classical curve, i.e. an increase during the most active phase of lipid accumulation in maturating seeds, followed by a rapid decrease until the end of seed maturation Brassica napus
