Restriction fragment length polymorphisms between Larix leptolepis and Larix decidua were identified in heterologous hybridization experiments, using wheat mitochondrial DNA probes specific for atp9, coxI, nad3/rps12, and orf25. Analysis of eight individuals of each reciprocal hybrid of these two species revealed that mitochondrial DNA was maternally inherited. Furthermore, sequences homologous to wheat orf25 were also identified in Larix gmelini, Larix siberica, Larix olgensis, and Larix laricina, as well as Ginkgo biloba, Picea mariana, Picea glauca and Pinus contorta.
在异源杂交实验中，使用针对 atp9、coxI、nad3/rps12 和 orf25 的小麦线粒体 DNA 探针，鉴定了落叶松和落叶松之间的限制性片段长度多态性。对这两个物种的每个正反杂交个体的 8 个个体进行分析，结果表明线粒体 DNA 是母系遗传的。此外，在欧洲赤松、北美云杉、兴安落叶松和长白落叶松以及银杏、黑云杉、白云杉和扭叶松中，也鉴定到了与小麦 orf25 同源的序列。
