Altogether, these information corroborated that natural variation inside the coding sequence of YUC8 and YUCCAdependent root auxin accumulation determines the extent with the root foraging response to mild N deficiency.Auxin tunes LR foraging downstream of BR signaling. Our preceding operate showed that BR biosynthesis and signaling are involved in regulating root elongation below low N24,25. We then explored a possible interdependence and hierarchy in auxin- and BR-dependent coordination of LR elongation in response to LN. For that reason, we generated a bsk3 yuc8 double mutant, which showed substantially shorter LRs than the wild variety under LN but no additive effect in comparison to the single mutants bsk3 and yucNATURE COMMUNICATIONS | (2021)12:5437 | doi/10.1038/s41467-021-25250-x | www.nature.com/naturecommunicationsNATURE COMMUNICATIONS | doi/10.1038/s41467-021-25250-xARTICLEFig. three Allelic variants of YUC8 cause variation in LR length at low N. a Association of 17 polymorphic sites (MAF 0.05) within the coding area of singleexon gene YUC8 in 139 re-sequenced accessions with typical LR length below higher N (HN, 11.4 mM N; red) or low N (LN, 0.55 mM N; cyan). The x-axis shows the nucleotide position of each variant. The y-axis shows the -log10 (P-value) for the association test working with a generalized linear model (GLM), having a significance level at = 0.05 indicated having a dashed red line. The six polymorphisms chosen for further analysis have been projected onto a schematic representation of a YUC8 gene structure represented by a light blue arrow. b Typical LR length of all-natural accessions representing two key YUC8 haplotypes (n = 126 and 10 accessions for haplotype A and haplotype B, respectively).
