Extended Data Fig. 8: Root phenotypes and the ratio of root to shoot biomass of NIL-RNR10HJX74-DNR1HJX74, NIL-RNR10IRAT261, NIL-DNR1IRAP9, and NIL-RNR10IRAT261-DNR1IRAP9.

a, Root systems of NIL-RNR10HJX74-DNR1HJX74, NIL-RNR10IRAT261, NIL-DNR1IRAP9, and NIL-RNR10IRAT261-DNR1IRAP9 plants. Scale bar, 10 cm. b, The ratio [(LN-HN)/HN] of total length of visible roots. c, The absolute value of total length of visible roots. d, The ratio [(LN-HN)/HN] of total area of visible roots. e, The absolute value of total area of visible roots. f, 15NO3− uptake rates. g, The ratio [(LN-HN)/HN] of root to shoot biomass ratio. h, The absolute value of ratio of root to shoot biomass. b-h, Different letters denote significant differences (P < 0.05) from a Duncan’s multiple range test. Exact P values are listed in Supplemental Information Table 11. Data are mean ± s.e.m. (n = 3 biologically independent samples).
