SEQUENCE-ANALYSIS OF A 40-KB ARABIDOPSIS-THALIANA GENOMIC REGION LOCATED AT THE TOP OF CHROMOSOME-1

As a contribution to the European Scientists Sequencing Arabidopsis (B IOTECH ESSA) project, a contig of almost 40 kb has been sequenced at t he extreme top of chromosome 1, around the Arabidopsis thaliana gene c oding for a member of the 1-aminocyclopropane-1-carboxylate synthesis gene family. The region contains, besides the ACS1 gene itself, 10 put ative genes, all new for Arabidopsis. Among these are three genes enco ding kinases, a late embryogenesis-abundant protein, a MADS box-contai ning protein, a dehydrogenase, and a Myb-related transcription factor. In addition, six cDNAs have been sequenced that correspond to this re gion. (C) 1998 Elsevier Science B.V. All rights reserved.
