GWAS and network analysis of tiller height across a panel of wheat accessions. a Manhattan plots showing the SNP marker-trait associations for the length of the peduncle, the second internode, the third internode, and the fourth internodes. Orange dots indicate SNPs above the significance threshold (− Log10[P-value] = 5.0). b Association networks across different traits in wheat. The nodes represent plant architecture traits and their associated loci. Longest tiller length, LTL; shortest tiller length, STL; length difference between longest and shortest tiller; longest tiller-shortest tiller length LSTL; main shoot length, MSL; peduncle length, PL; second internode length, SIL; third internode length, TIL; fourth internode length, FIL. The eight traits are indicated by different colors. The edges between the loci from different traits are linked by their LD. Only the edges with an average LD ≥ 0.5 are displayed. The orange solid circles indicate the four loci that are specifically associated with the length of the two internodes. The overlapping loci covering Rht-D1, TaPIN1-6D, Ppd-D1, and TaTB1-4D are indicated by the orange dashed circles. c Distribution of XP-CLR scores (Chinese landraces versus cultivars) for 21 wheat chromosomes. The selected regions and candidate genes detected based on their p ratio are shown. The genome-wide threshold was defined by the top 5% of values
