Abstract
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 DAH P synthase isoforms. The deduced amino acid sequences are 79% identica l. A comparison of the known Solanaceae DAHP synthases indicates two d istinct conserved isoforms. The steady-state levels of transcripts of the two tomato genes differ in all organs analysed.
