摘要:采用SSAP分子標(biāo)記技術(shù)對(duì)田間自然產(chǎn)生的紅富士蘋(píng)果(Malus domestica)新芽變材料及其對(duì)照進(jìn)行了遺傳鑒定。結(jié)果表明,一個(gè)376 bp DNA片段為芽變材料特異性片段,其序列與蘋(píng)果查爾酮合成酶(CHS)基因啟動(dòng)子同源性達(dá)90%,表明芽變材料是遺傳物質(zhì)發(fā)生改變的穩(wěn)定變異,為進(jìn)一步研究芽變材料發(fā)生性狀變異的分子機(jī)理奠定基礎(chǔ)。

Abstract: Fuji apple bud mutation and the wild type were analyzed by SSAP. The results showed that a DNA fragment of 376 bp in length was specific fragment of Fuji apple bud mutation, and it was up to 90% homology with the promoter of chalcone synthase(CHS) gene. It indicated that Fuji bud mutation was stable mutation of the genetic material changes, and laid a basis for further research on the molecular mechanism of bud mutation.
Key words: apple(Malus domestica); bud mutation; SSAP; analysis
