Oxidative stress parameters measured in Miscanthus xA

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.
Table 5.
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.
