Tomato (Lycopersicon esculentum L. cv. UC82b) was found to contain two distinct 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase genes that are differentially expressed. The corresponding cDNAs were isolated and characterized. Both genes code for putative plastidic DAHP synthase isoforms. The deduced amino acid sequences are 79% identical. A comparison of the known Solanaceae DAHP synthases indicates two distinct conserved isoforms. The steady-state levels of transcripts of the two tomato genes differ in all organs analysed.
番茄（Lycopersicon esculentum L. cv. UC82b）被发现含有两个不同的且差异表达的3-脱氧-D-阿拉伯庚酮糖酸-7-磷酸（DAHP）合酶基因。相应的cDNA被分离并进行了表征。这两个基因都编码假定的质体DAHP合酶同工型。推导的氨基酸序列有79%的同一性。对已知茄科DAHP合酶的比较表明存在两种不同的保守同工型。在所有分析的器官中，这两个番茄基因转录本的稳态水平有所不同。
