The methylation of cytosine bases with DNA molecules (DNA methylation) is a heritable epigenetic modification that has been previously demonstrated to regulate the expression of a number of genes without permanent changes to their DNA sequence.

 

Dr. Joseph R. Ecker

Joseph R. Ecker, a professor in the Plant Biology Laboratory, is one of the nation’s leading authorities on the molecular biology and genetics of plants. Ecker was a principal investigator in the multinational project that sequenced the genome of Arabidopsis thaliana,  a modest weed that has become a model organism for the study of plant genetics. This wild mustard variety is the first plant to have its genome sequenced, an achievement expected to have widespread implications for agriculture and perhaps human medicine as well.

Ecker is also widely regarded as one of the foremost experts on how the gaseous hormone ethylene regulates a variety of basic plant processes. For agriculture, ethylene gas is a vital chemical messenger important for such processes as fruit ripening and how plants respond to pathogenic organisms.
