クロマツとタイワンアカマツとの種間雑種における葉緑体およびミトコンドリア DNAの遺伝様式

近藤頑二(1)・津村義彦(2) ・河原孝行(3)

要旨:クロマツとタイワンアカマツとの種間雑種における葉緑体DNAおよびミトコンドリア DNAの遺伝様式を調

べた。雑種 15個体から全DNA を単離し、葉緑体DNAについては、制限酵素 EcoRIで切断後、タバコの葉緑体DNA

の断片pTB8 をプローブにしてサザンハイブリダイゼーションを行ったところ、 14個体はすべて父親であるタイワ

ンアカマツと同じバンドパターンを示したが、 1 f固体は明瞭なバンドを示さなかった。ミトコンドリアDNAについ

ては、制限酵素 ApaI で切断後、 PCR で増殖した coxI の遺伝子をプローブにしてサザンハイブリダイゼーションを

行ったところ、 14個体はすべて母親であるクロマツと同じバンドパターンを示したが、 1 個体は明瞭なバンドが出

なかった。以上のことから、この雑種においては、葉緑体DNA は父性遺伝し、ミトコンドリア DNA は母性遺伝し

ていると考えられた。また、 PCR で増殖したクロマツの coxI 遺伝子の一部の塩基配列を明らかにした。
