From: Beyond nitrate transport: AtNRT2.4 responds to local and systemic nitrogen signaling in Arabidopsis

AtNRT2.4 enhances anthocyanin synthesis and accumulation in the leaves of A. thaliana under low nitrate conditions. a Leaf phenotypes of diverse A. thaliana lines following short-term N starvation and nitrate resupply. Scale bar = 1 cm. b-e Expression levels of anthocyanin biosynthesis and accumulation-related genes AtDFR, AtANS, AtTT8, and AtPAP2 in whole A. thaliana plants following short-term N starvation and nitrate resupply. Data represents mean ± SE (n = 4). The letters above the horizontal lines are based on Tukey's HSD test (p < 0.05), with LN and NN groups comparisons
