We have isolated two nitrate reductase genes and their corresponding cDNAs from Arabidopsis thaliana. Sequences of the two cDNAs, when compared to a sequence of a barley cDNA clone, confirm their identity as nitrate reductase clones and show that they are closely related. The two genes have been mapped using restriction fragment length polymorphisms; gNR2 is close to the previously identified chl-3 locus and is probably identical to it, while gNR1 maps to a new locus (NIA1) on chromosome 1, near gl-2.
我们从拟南芥中分离出了两个硝酸还原酶基因及其相应的cDNA。将这两个cDNA的序列与一个大麦cDNA克隆的序列进行比较后,证实了它们作为硝酸还原酶克隆的身份,并表明它们密切相关。利用限制性片段长度多态性对这两个基因进行了定位;gNR2靠近先前鉴定的chl-3位点,可能与之相同,而gNR1定位于第1号染色体上靠近gl-2的一个新位点(NIA1)。
