图3 三种可能存在的基因组大小分布模式。红色箭头代表环境因素施加的选择压力, 箭头越大代表选择压力越强。DS: 基因组小的劣势; AS: 基因组小的优势; AL: 基因组大的优势; DL: 基因组大的劣势。

Fig. 3 Three potential distribution patterns of genome size in angiosperms. The red arrows indicate the selection pressure exerted by environmental factors, with larger arrows representing stronger pressures. DS, Disadvantages of smaller genome size; AS, Advantages of smaller genome size; AL, Advantages of larger genome size; DL, Disadvantages of larger genome size.
