a
Codes “K01”, “H01” and “rOTU” represent “flowerbed sample with experimental code” , “agricultural field sample with experimental code” and “SSU rDNA-derived OTU”, respectively. Two-digit serial numbers were assigned in order of the number of nematodes in the rOTU.
b
Nematodes isolated from flowerbed and agricultural field soils were designated as SnTUT_k01_a two-digit serial number and SnTUT_h01_a two-digit serial number, respectively.
c
Feeding types were derived from those of nematode species with the highest sequence homologies by Blast search according to the references in Yeates et al. (1993) [41]. Numbers and letters in parentheses indicate feeding types in the reference.
d
Feeding type for H01rOTU02 was derived from the other reference [44].
