The experiment was carried out to study the effect of temperature on (Me-14C) choline uptake in cotton roots and its incorporation into phosphatidylcholine. The results suggest that (Me-14C) uptake and incorporation increased with increased germination time. Temperature above 35C had significant effect on (Me-14C) choline uptake and incorporation. Thus, as the temperature increased above 35C, the rate of synthesis of phosphatidylcholine decreased. At 50C, however, more than 80% of the phosphatidylcholine synthesis was inhibited.
