Supplementary Figure S2: BnaGLN1 genes localisation on LG using mono- and polysomic additional lines. Amplification of specific DNA fragment for each BnaGLN1 gene was performed on mono- and polysomic additional lines selected among the descendants from a cross between Brassica napus Darmor-bzh and Brassica rapa C1.3. Each line is carrying the full A genome (mixture from B. napus and B. rapa) and one or several C chromosomes originating from Brassica napus Darmor-bzh.

BnaGLN1 genes relative expression level was monitored in primary veins of six leaf ranks harvested on vegetative plants grown under low (white bars) or high (black bars) nitrate conditions. Leaf ranks represented as number 1 (bottom and older leaf) to 6 (top and younger leaf) showed differential senescence symptoms. Mean and standard deviation of four plant repeats are shown.
