Fig. 6From: Genome-wide identification and expression analysis of the NRT genes in Ginkgo biloba under nitrate treatment reveal the potential roles during calluses browningExpression of GbNRTs during callus browning under nitrate treatments at 17 DAC and 26 DAC. Twenty-three GbNRTs (14 IB GbNRTs (A) and 9 PB GbNRTs (B) were selected for RT-qPCR, each performed with three biological replicates. Data are presented as means ± SD and were normalized by the reference gene GbUBQ. LN treatments are represented by green boxes, while HN treatments are depicted by yellow boxes. Statistical analysis was performed using one-way ANOVA for each treatment (* p < 0.05, ** p < 0.01)Back to article page
