Simultaneous Inhibition of Linolenic Acid Synthesis in Winter Wheat Roots and Frost Hardening by BASF 13-338, a Derivative of Pyridazinone.
Treatment of 12-day-old winter wheat (Triticum aestivum) plants with BASF 13-338 {4-chloro-5 (dimethylamino)-2-phenyl-3(2H)-pyridazinone} 36 hours before frost hardening simultaneously and completely inhibits accumulation of linolenic acid in the roots during the hardening period and the acquisition of frost resistance. Increased unsaturation of fatty acids is therefore probably an important pa...
متن کاملDifferential Effects of a Substituted Pyridazinone, BASF 13-338, on Pathways of Monogalactosyldiacylglycerol Synthesis in Arabidopsis.
We have examined the effects of the substituted pyridazinone herbicide, 4-chloro-5-(dimethylamino)-2-phenyl-3(2H)pyridazinone (BASF 13-338, Sandoz 9785), on the desaturation of linoleic acid (18:2) on different molecular species of monogalactosyldiacylglycerol (MGDG) and phosphatidylcholine (PC) in leaf tissue of Arabidopsis thaliana (L.) Heynh. Specific changes in lipid composition allowed ide...
متن کاملEffect of Temperature and BASF 13 338 on the Lipid Composition and Respiration of Wheat Roots.
The fatty acid composition of wheat seedling roots changed in response to temperature. As temperature declined, the level of linolenic acid increased and the level of linoleic acid decreased. The distribution of phospholipid classes was not influenced by temperature. Phosphatidyl choline and phosphatidyl ethanolamine were the predominant phospholipids isolated and comprised 85% of the total lip...
متن کاملStimulation of Phospholipid Biosynthesis during Frost Hardening of Winter Wheat.
Lipids were labeled with (33)P during frost hardening of two varieties of winter wheat (Triticum aestivum), hardy Kharkov and much less hardy Champlein. The main labeled compounds were phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylglycerol. With time of incorporation the proportion of the radioactivity incorporated into the lipids increased in phosphatidyl...
