3.4. Effects of TE soil contamination and AMF inoculation on fatty Neuropeptide Y composition of Miscanthus
The fatty acid composition of Miscanthus is shown in Table 5. The FA contents were similar in plant roots grown in contaminated or in non-contaminated soil. C18:2 was the predominant FA in roots and represented approximately 45% of the total amount of FA. In the roots of non-inoculated plants cultivated in the contaminated soil, an increase in C18:2 and a decrease of C16:0 and of the ratio between saturated and unsaturated FAs were detected in comparison to the value determined for the roots of inoculated plants.
AMF inoculation induces an increase in C16:0 in the roots of plants cultivated in non-contaminated soil. Under these conditions, an increase in the saturated/unsaturated FA ratio was also observed.
In leaves, five FAs were detected: C16:0, C18:0, C18:1, C18:2 and C18:3 (Table 5). The last of these FAs, known as linolenic acid, was predominant, representing more than 70% of the total FA composition.
