The mode of inheritance of chloroplast and mitochondrial DNA (mtDNA) in rye x triticale intergeneric hybrids has been studied with the use of specific PCR markers for loci 18S/5S and 3'rbcL in organelle DNA. In rye x triticale BC1, mtDNA copies of two types, paternal and maternal, have been found; in BC2 plants, only paternal mtDNA and chloroplast DNA (cpDNA) have been detected. Mechanisms determining the inheritance and/or differential amplification of organelles of a specific type are discussed.
利用针对细胞器DNA中18S/5S和3'rbcL位点的特异性PCR标记，研究了黑麦与小黑麦属间杂种中叶绿体和线粒体DNA（mtDNA）的遗传模式。在黑麦×小黑麦BC1代中，发现了两种类型的mtDNA拷贝，即父本型和母本型；在BC2代植株中，仅检测到父本mtDNA和叶绿体DNA（cpDNA）。本文讨论了决定特定类型细胞器遗传和/或差异扩增的机制。
