Doctoral Researcher Position (Ref.No. ILRS_01/2015)
Opportunistic mutualistic bacterial associations of Nicotiana attenuata

Plants are embedded in the enormous amount of microbial life that lives in the soil in which they grow, and we have been able to show that a native plant recruits particular bacterial taxa from the soil to help solve various physiological challenges they face and thereby establish opportunistic mutualisms. This project will build on this work and can follow a number of different research paths, as long as the research illuminates in some way the fitness consequences of the bacterial association for the plant.

The native annual tobacco ( Nicotiana attenuata ) germinates after fires in the Great Basin Desert to grow in the primordial agricultural niche of a post-fire environment and copes annually with an unpredictable community of herbivores and pathogens. N. attenuata has been developed as an ecological model plant for more than two decades during which hundreds of transgenic plant-lines have been released on a field station in Utah, USA to identify and functionally test genes relevant for survival in nature [for example, see, 1]. A collection of plant-associated bacteria from N. attenuata with plant growth promoting effects have been identified [2], and one in particular has been studied in detail, and shown to increase the availability of reduced sulfur for their host plant [3], and increase survival of ethylene deficient plants in nature [4]. We have characterized a fungal pathogen outbreak in a native population [5], components of which likely proliferated into a wilt disease in our field plantations and more recent work has shown that consortia of 5-6 of the native bacteria can be used as biocontrol agents that protect plants from this fungal wilt disease. Hence, inoculation of N. attenuata with a small core-set of the root-associated bacterial community was sufficient to rescue field grown plants from a wilt disease which emerged by continuous cropping. The inoculated bacteria had antagonistic effects against the pathogen and dramatically reduced plant mortality. The main goal of this project is to unravel the (multiple) possible mechanisms likely involved in this fungal biocontrol mutualism using the ecological, molecular and metabolomics toolboxes established in the department of Molecular Ecology of the Max Planck Institute for Chemical Ecology.
