图2. 提高C3植物氮素利用率(NUE)的途径(改自Nowicka et al., 2018)
向上(绿色)和向下(红色)箭头分别表示需提高和限制的目标路径和酶活性。Rubisco: 核酮糖-1,5-二磷酸羧化酶/加氧酶; 2-PG: 磷酸乙醇酸; CCM: CO2浓缩机制

Figure 2. Strategies for improving nitrogen use efficiency (NUE) of C3 plants (modified from Nowicka et al., 2018)
Pathways/enzymes for activation are marked in upwards arrows (green), while those for repression are marked in downwards arrow (red). Rubisco: Ribulose bisphosphate carboxylase oxygenase; 2-PG: 2-phosphoglycolate; CCM: CO2 concentrating mechanism
