Table S1 Summary of species or species groups and their root attributes that were identified in an old field using the rbcL DNA barcode. We indicate the best match between the query sequence and the KSR reference database, based on base pair identity (%) and the match score, which reflects number of base pairs as well as identity. All best matches were statistically significant (E < 0.05). We also indicate species or species group designation used in this study.

Fig. S1 Mean (±SE) concentration of total nitrogen, phosphorus, potassium, and magnesium and pH as function of depth in four soil plots at Koffler Scientific Reserve (KSR), Ontario, Canada. Soil samples were collected from 0–10, 20–30, 40–50, 60–70, and 80–90 cm within one soil column per plot.
