Frankia is an actinobacterium that fixes nitrogen under both symbiotic and free-living conditions. We identified genes upregulated in free-living nitrogen-fixing cells by using suppression subtractive hybridization. They included genes with predicted functions related to nitrogen fixation, as well as with unknown function. Their upregulation was a novel finding in Frankia.
弗兰克氏菌是一种放线菌,能够在共生和自由生活条件下固定氮。我们通过抑制消减杂交技术鉴定了自由生活固氮细胞中上调的基因。它们包括具有预测固氮功能以及未知功能的基因。它们的上调在弗兰克氏菌中是一个新的发现。
