Abstract A cDNA clone (TAB2) encoding a nucleoside diphosphate (NDP) kinase has been isolated from a tomato (Lycopersicon esculentum Mill. cv. Ailsa Craig) cDNA library. The clone is 590 bp long and exhibits a high degree of sequence identity with spinach NDP kinases I and II, Pisum sativum NDP kinase I, Arabidopsis thaliana NDP kinase, Drosophila melanogaster NDP kinase, Dictyostelium discoideum NDP kinase and human Nm 23-H1 and Nm23-H2. Northern analysis has revealed that the mRNA encoded by TAB2 is up-regulated in both leaf and stem tissue in response to wounding. The increase is apparent within 1 h of wounding and is not further elevated by application of ethylene. Southern blot analysis indicates that TAB2 is a member of a small gene family.
