Data were taken from aLiu L. et al. (2023) and bLiu et al. (2017a).†Summed features are groups of two or three fatty acids that cannot be separated by GLC using the MIDI system. Summed feature 2 comprised C12:0 aldehyde and unknown 10.9283, summed feature 3 comprised C16:1ω7c and C16:1ω6c, and summed feature 8 comprised C18:1 ω7c and/or C18:1 ω6c. The major fatty acids (>10%) are maked bold.
