Table 4. Effect of mycorrhizal colonization on fatty acid abundance in roots of wild-type (WT) and spr2 mutant tomato plants.

Fatty acids were quantified in roots of control and mycorrhizal plants of both genotypes, sampled after a 45 dpi mycorrhizal colonization period¹.

Notes:

¹FA analysis was performed by GC–MS.

²% Abundance determined using the mean peak areas of each FA.

³Numbers in bold in a green background indicate a significantly higher ratio.

⁴Numbers in bold in a orange background indicate a significantly lower ratio.
