CPSC lecture by Renate Müller

Professor Renate Müller, Section for Crop Sciences, PLEN, University of Copenhagen will give a CPSC Lecture on November 10 at 15.00-16.00. Everybody is welcome.


Naturally transformed plants – using nature’s toolbox
Compactness is a desirable trait in ornamental plant breeding and preferred by producers, distributors and consumers. In ornamental plant production growth is regulated by application of chemical growth retardants, several of which are harmful to both the environment and human health. Natural transformation using the soil born bacterium Agrobacterium rhizogenes can be the future’s bio-friendly alternative to chemical growth regulators.

Professer Renate Müller, PLEN, KU

This biotechnological method does neither rely on the use of recombinant DNA technology nor depend on undesired antibiotic resistance markers. Hairy roots function as the primary indicator of transformation success. In Denmark the authorities have confirmed that plant products developed using natural transformation by unmodified strains of A. rhizogenes are not considered as genetically modified (GM) plants.

Naturally transformed plants exhibit various interesting phenotypes. The transferred rol-genes cause increased rooting, decreased plant height, short internodes, reduced apical dominance and changes in flower characteristics. Several of these traits improve ornamental plant quality and may also benefit traits of agricultural field crops. Noteworthy, several plants containing rol-genes contain higher contents of secondary metabolites compared to wildtype plants. Naturally transformed plants result in promising traits in several plants and appear to be useful new biotechnological tool in the breeder’s toolbox.
