Description:
A mobile endogenous transposable element, Tag1, has been identified in the plant Arabidopsis thaliana. Tag1 was found in the nitrate transporter gene, CHL1, of a chlorate-resistant mutant present in a population of plants containing an active maize Ac transposon. Tag1 excises from the chl1 gene producing chlorate-sensitive revertants with Tag1 or Tag1-related elements at different loci. Tag1 and related elements are present in the Landsberg but not Columbia or Wassilewskija ecotypes of Arabidopsis. Thus, Tag1 provides a tool for the insertional mutagenesis of plant genes essential for biological processes of agronomic importance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsay, Y F -- Frank, M J -- Page, T -- Dean, C -- Crawford, N M -- 5T32CA09345-12/CA/NCI NIH HHS/ -- GM 40672/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 16;260(5106):342-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla 92093-0116.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8385803" target="_blank"〉PubMed〈/a〉
