Chromosomal locations of QTLs for shape and size variation in Leaf4, Leaf7, petal, Leaf4-Petal, Leaf7-Petal and life history traits in MAGIC lines. The chromosomal location of identified QTLs is shown on the five Arabidopsis chromosomes. Each QTL is indicated by a line segment, with the extent of the line indicating the 95% confidence region and the peak SNP shown by a long vertical line in the QTL region. QTLs for different traits are shown in different colours: the QTLs for Leaf4 allometry are shown in dark green and named LF4 (LF4_1, Leaf4.PC1; LF4_2, Leaf4.PC2); the QTLs for Leaf7 allometry are shown in blue and named LF7 (LF7_1, Leaf7.PC1; LF7_2, Leaf7.PC2; LF7_3, Leaf7.PC3); the QTLs for petal allometry are shown in red and named PE (PE_1, Petal.PC1; PE_2, Petal.PC2); the QTLs for Leaf4-Petal shape and size covariation are shown in light green and named L4PE (L4PE_1, Leaf4-Petal.PC1; L4PE_2, Leaf4-Petal.PC2; L4PE_3, Leaf4-Petal.PC3; L4PE_4, Leaf4-Petal.PC4); the QTLs for Leaf7-Petal shape and size covariation are shown in orange and named L7PE (L7PE_3, Leaf7-Petal.PC3; L7PE_4, Leaf7-Petal.PC4); the QTLs for life-history traits are all shown in the dark (BN, branch number; DB, days to bolting; DF, days to flower; RN, rosette leaf number; SH, stem height)
