Table 3. Effect of mycorrhizal colonization on metabolite abundance in leaves of wild-type (WT) and spr2 mutant tomato plants.

Metabolite quantitation was determined in leaves of control and mycorrhizal plants of both genotypes, sampled after a 45 dpi mycorrhizal colonization period¹.

Notes:

¹The targeted metabolite analysis was performed by GC–MS.

²The ratios were determined using the mean peak areas of each compound.

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

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