The photosystem I complex from Nicotiana tabacum, which has an alloploid genome, contains subunits of 17.5 and 18.5 kilodaltons whose N-terminal amino acid sequences are highly homologous. Comparative analysis of photosystem I subunits among N. tabacum and its ancestral plants, N. tomentosiformis and N. sylvestris, revealed that the 17.5 kilodalton subunit of N. tabacum derives from N. sylvestris, and the 18.5 kilodalton subunit from N. tomentosiformis.
具有异源多倍体基因组的烟草光系统I复合体包含17.5千道尔顿和18.5千道尔顿的亚基，其N端氨基酸序列高度同源。对烟草及其祖先植物绒毛状烟草和林烟草的光系统I亚基进行比较分析发现，烟草的17.5千道尔顿亚基来源于林烟草，18.5千道尔顿亚基来源于绒毛状烟草。
