The rice (Oryza sativa L. var. Labelle) chloroplast (cp) gene encoding cytochrome f has been isolated and sequenced. The coding region of this rice gene displays 95.1%, 85.3% and 85.2% nucleotide sequence homology with that of wheat, pea and spinach, respectively. To examine the cpDNA sequence variation in rice, cpDNA from Labelle and its parents, Belle Patna and Dawn was compared. Using the cytochrome f gene as the probe for hybridization, we found several differences in the size and number of restriction fragments in the cp genome of three rice varieties. An additional restriction fragment found in the Belle Patna cp suggests that this cp genome is either heterogeneous or contains two copies of cytochrome f gene per cpDNA.
已分离并测序了编码细胞色素f的水稻（Oryza sativa L. var. Labelle）叶绿体（cp）基因。该水稻基因的编码区与小麦、豌豆和菠菜的编码区核苷酸序列同源性分别为95.1%、85.3%和85.2%。为研究水稻叶绿体DNA（cpDNA）序列变异，比较了Labelle及其亲本Belle Patna和Dawn的cpDNA。以细胞色素f基因为杂交探针，我们发现三个水稻品种cp基因组中限制性片段的大小和数量存在若干差异。在Belle Patna cp中发现的一个额外限制性片段表明，该cp基因组要么是异质的，要么每个cpDNA含有两个细胞色素f基因拷贝。
