Mapping of a locus required for resistance under high nitrogen. The Nipponbare X Kasalath CSSL mapping population was scored for NIS to the GUY11 isolate (see Methods). A. The CSSL5, CSSL19 lines and two recombinant lines (19-42-2 and 19-42-4) identify chromosome 1 as carrying a Kasalath locus conferring susceptibility under high nitrogen treatment. The portions of the chromosome in black, white and dashed respectively correspond to Kasalath, Nipponbare and heterozygous as established by microsatellites markers (RM markers indicated on the left of the figure). Possible regulators of disease resistance and nitrogen metabolism are indicated for the NIS1 locus on the right of the figure. B. Plants from the 19–42 family segregating at the NIS1 locus were grown under low (0 N) or high nitrogen (1 N) and genotyped with several markers flanking the NIS1 locus. The genotype at NIS1 is indicated. Quantitative phenotype of these group of plants with similar genotype (the number of individual plants is indicated) was established after inoculation with the GUY11 isolate. Statistical differences are shown by *** (p value < 0.001; Wilcoxon test).
