Furthermore, the results from monitoring the infection process of GFP-TR4 in roots and corms indicated that the GFP-TR4 mycelium in plants inoculated with YNF2217+TR4 was lower than that in the treatment of only inoculated with TR4 on day 1, day 7, day 14, and day 45 after TR4 inoculation. This evidence concerns the gene NR2C2 and infection.
