Abstract

Agrobacterium tumefaciens is a gram-negative bacterium with the unique capacity to induce neoplasmic transformations in dicotyledonous plants. Recently, both the mechanism and the biological significance of this transformation have been elucidated. Agrobacterium tumefaciens strains contain a large extrachromosomal DNA plasmid (the Ti-plasmid). This Ti-plasmid is responsible for the oncogenic properties of Agrobacterium strains. A particular segment of the Ti-plasmid, containing information determining the tumorous growth pattern and the synthesis of so-called 'opines', e.g. octopine (N-alpha-(D-1-carboxyethyl)-L-arginine) and nopaline (N-alpha-(1,3-dicarboxypropyl)-L-argine), is transferred and stably maintained and expressed in the transformed plant cells. This phenomenon can be understood as a 'genetic colonization' of the plant cells by bacterial plasmid DNA so that the transformed plant cells will produce and secrete into the medium amino acid derivatives (the opines) that Ti-plasmid carrying agrobacteria can selectively use as carbon and nitrogen sources.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
