Abstract
We report the cloning of a cDNA for MEK1, an Arabidopsis thaliana gene encoding a homologue of MAP kinase kinase (MEK). The predicted protein sequence shows 41% identity over 270 amino acids to vertebrate MEK proteins, and contains conserved features characteristic of MEK. Analysis of transcript levels show that expression of the gene is regulated by developmental processes (etiolation/de-etiolation) and by wounding. However in contrast to the rapid wound induction of MAP kinase transcripts in other plant species, MEK1 transcripts first accumulated 6-12 h after wounding.
