Deadnettles belong to the genus Lamium which includes several species of flowering plants in the family Lamiaceae. They are all herbaceous plants native to Europe, Asia, and northern Africa. This book discusses the applications of biochemical and molecular markers for assessing the genetic diversity and phylogenetic relationships of Lamium germplasm in order to provide developed technologies for crop improvement. This book is of interest to plant geneticists, plant breeders, researchers, and scientists.
