TOE1-miRNA172 resistant lines, 35S:TOE1R and target mimicry lines for miRNA172 show resistance to root-nematode infection under short days. (a) In vitro grown analysis of 35S:TOE1R lines A12, D81, E82 and G73 (in light grey); and mimicry (MIM) lines 7 and 23 (dark grey). The percentage of galls per main root was significantly lower in all lines studied than ecotype Col-0 (black). At least 80 plants per line were analyzed. (b) Soil reproduction tests for 35S:TOE1R lines A12, D81 and G73; and MIM lines 7 and 23. The percentage of number of eggs per root weight was lower in all lines than in Col-0 (P < 0.05). At least 30 plants per line were analyzed. Asterisks, significant differences (T-Student; P < 0.05). Three independent experiments were performed for each treatment. Values are means ± SE.
