Linear plasmids of microbes represent a heterogenous group of extrachromosomal genetic elements initially assumed to be rare and peculiar. However, we now know that they are fairly frequently occurring plasmids in bacterial and eukaryotic species. Viral strategies to avoid shortening of the linear molecules during replication imply a common ancestry. Linear plasmids may be beneficial, neutral or detrimental for the respective host; functions include production of protein toxins, specific catabolic capabilities, antibiotic resistance, pathogenicity factors, and senescence induction.

In this first decade of the 21st century, more than 854 million people in the world are starving, while industrial nations are debating about obesity, generating energy from food plants, and a myriad of other topics many African and south Asian nations could only fathom. In this great discord, there have arisen many interdisciplinary discussions about problems in the field of applied Ethics, with regards to food, that are crossing a considerably wide spectrum of disciplines, such as: obesity, traceability, agro-food biotechnology, dairy industry, transgenic plants, novel food, bio fuels,...
