A restriction endonuclease fragment map of sugar beet chloroplast DNA (ctDNA) has been constructed with the enzymes SmaI, PstI and PvuII. The ctDNA was found to be contained in a circular molecule of 148.5 kbp. In common with many other higher plant ctDNAs, sugar beet ctDNA consists of two inverted repeat sequences of about 20.5 kbp separated by two single-copy regions of different sizes (about 23.2 and 84.3 kbp). Southern hybridization analyses indicated that the genes for rRNAs (23S+16S) and the large subunit of ribulose 1,5-bisphosphate carboxylase were located in the inverted repeats and the large single-copy regions, respectively.
已构建了甜菜叶绿体 DNA (ctDNA) 的 SmaI、PstI 和 PvuII 限制内切酶片段图谱。ctDNA 被发现包含在一个 148.5 kbp 的环状分子中。与许多其他高等植物 ctDNA 一样,甜菜 ctDNA 由大约 20.5 kbp 的两个反向重复序列组成,它们被两个大小不同的单拷贝区隔开(约 23.2 和 84.3 kbp)。Southern 杂交分析表明,rRNA(23S+16S)和核酮糖 1,5-二磷酸羧化酶大亚基的基因分别位于反向重复序列和大单拷贝区。
