Seven other RSA traits were modified in both IL99 and Ruta reflecting the common response to LN (Figure 3a–g ) but showed a highly significant change in IL99 ( p < 0.00001) and lower significance in Ruta, including maximum number of roots*, number of root tips, total root length*, network area*, volume, surface area, and holes* (i.e., traits marked with* were advantageous in IL99 over Ruta under the LN treatment (Figure 3a–g ).
