Newly isolated leaf dwelling symbiont of yam (Dioscorea bulbifera) can increase plant biomass when applied to tomato.


Johannes B. Herpell and colleagues from the Weckwerth group found that the Betaproteobacterium Paraburkholderia sp. strain Msb3 exhibits significant growth promotion when applied to agriculturally important plants such as tomato, increasing the total dry biomass by up to 40%. The strain was isolated from leaves of the potato yam, Dioscorea bulbifera, with witch it was shown to engage in a stable long term symbiotic relationship.

New Project "Water's gateway to heaven"


Ingeborg Lang is partner in 4-year WWTF project on 3D imaging and modeling of transient stomatal responses in plant leaves under dynamic environments.

Stomata cover less than 5 % of the leaf surface and yet, they facilitate the majority of gas exchange between the atmosphere and terrestrial vegetation. The opening of stomata is adjusted to provide carbon dioxide influx for photosynthesis and to limit water loss. Fluctuating environmental conditions infuence stomata responses and consecutively productivity and water use efficiency in crops and natural ecosystems.

In this project, we apply novel temporal 3D imaging for a better description and mechanistic understanding of stomatal movements. The combination of high resolution microCT, fluorescence microscopy and automated segmentation of images by novel computational methods allows to track stomatal movements from subcellular to whole leaf traits. We will answer long-standing questions on how to improve stomatal responses under changing environments to increase water-use efficiency and net productivity.

Combination of Fasting and Metformin Impairs Tumor Growth


Tumor growth can be prohibited with the right combination of fasting-induced hypoglycemia and metformin treatment. This was shown in a recent paper by Elgendy, Minucci and colleagues in collaboration with the Vienna Metabolomics Center.

In mice exposed to 24-h feeding/fasting cycles, metformin impaired tumor growth, but only when administered during fasting-induced hypoglycemia.

Synergistic anti-neoplastic effects of the metformin/hypoglycemia combination were mediated by glycogen synthase kinase 3β (GSK3β) activation downstream of PP2A, leading to a decline in the pro-survival protein MCL-1, and cell death. Mechanistically, specific activation of the PP2A-GSK3β axis was the sum of metformin-induced inhibition of CIP2A, a PP2A suppressor, and of upregulation of the PP2A regulatory subunit B56δ by low glucose, leading to an active PP2A-B56δ complex with high affinity toward GSK3β.

Open master thesis - research CAM photosynthesis in Costa Rica and Vienna


We are looking for a master student doing system-level investigation of CAM photosynthesis both in the Costa Rica rainforest and in our lab in Vienna.

Due to global climate change the different plant photosynthesis types C3, C4 and CAM will be of utmost importance in balancing net primary as well as global food production with all its subsequent consequences on the human society.

Typical C3 crop plants are wheat, rice and potato, C4 are maize and millet, and CAM are typical tropical crop plants such as ananas. For all of them genome sequences are available and enable a system-level analysis of the different types of photosynthesis.

The only so far known tree showing CAM-type photosynthesis is restricted to Clusia species. Knowledge here is very limited, especially the system-level understanding of this highly plastic plant able to switch from C3 to CAM. The student will work on different Clusia species in the field (research field station La Gamba) and with a large collection of different ecotypes in the lab.

For more information, please, contact wolfram.weckwerth@univie.ac.at

Pearl millet: genome sequence published


An international consortium with participation of MOSYS team members Palak Chaturvedi, Arindam Ghatak and Wolfram Weckwerth has published the genome sequence of drought- and heat-tolerant Pearl millet. The MOSYS team further developed a molecular-physiological model to explain drought and heat tolerance.

Pearl millet resists temperatures up to 42°C, unlike wheat, rice or corn. The resilient plant will be especially important in the era of global climate change. But how is this dryland cereal able to survive soaring temperatures and exceptional drought?

Wolfram Weckwerth explains: "Plant diversity and adaptation to different climatic conditions—especially important in the era of global climate change—is synonymous for the concept of natural and genetic diversity. Research tackling this natural genetic variation and the corresponding biodiversity provides one of the largest treasures of mankind.

Exactly this genetic variation of plant families, plant genera and even within one plant species is the key to cope with global climate change and dramatic consequences for agriculture.

For the purpose of sustainable research, breeding and protecting genetic diversity especially of crop plants many public non-profit research organization have formed under the umbrella of CGIAR and are active in research and building non-profit biobanks. ICRISAT, coordinator of the pearl millet genome sequencing studies, is the Indian pendant of the famous CIMMYT which started in the 60-70ies to distribute disease resistant and high yield wheat varieties under the poor farmers in the developing countries."

He further says, "the first steps to elucidate molecular mechanisms in any organism from plants to animals to microbes is to sequence and analyze their genome, proteome and metabolome. Subsequently, we draw hypotheses from these data by integration, modelling and functional interpretation.

Based on our studies we developed first molecular-physiological hypotheses to explain drought and heat tolerance of this plant. This will have a strong impact in understanding and improving plant productivity in changing climate in the next decades."

Benchtop Fractionisation Method for Subcellular Metabolomics


New fractionation technique for assigning metabolites to their subcellular localization developed by L. Fürtauer, W. Weckwerth and T. Nägele.

Although compartmentation is a key feature of eukaryotic cells, biological research is frequently limited by methods allowing for the comprehensive subcellular resolution of the metabolome. It has been widely accepted that such a resolution would be necessary in order to approximate cellular biochemistry and metabolic regulation, yet technical challenges still limit both the reproducible subcellular fractionation and the sample throughput being necessary for a statistically robust analysis. We present a method and a detailed protocol which is based on the non-aqueous fractionation technique enabling the assignment of metabolites to their subcellular localization.

ICRISAT and VIME partner in drought tolerance research for staple food crops using systems biology approaches


ICRISAT will partner the Vienna Metabolomics Center, University of Vienna, to study drought tolerance in chickpea and analyze the two-line hybrid system and epigenomics for hybrids in pigeonpea.

Agricultural and medical researchers and doctors from around the world came together from March 22 – 24, 2018, at ICRISAT to brainstorm on the connect with between microbiomes of the gut and the soil. This workshop on systems biology for human and plant nutrition aimed to elucidate the workings of microorganisms in the human body; the microbial connection between gut and brain/immune system/obesity as well as the factors influencing them (diet, genetics, environment). Experts from Ghana, India, Senegal, Mali and The Gambia presented their respective countries’ nutrition reports, highlighting the need for urgent interventions to improve nutrition. The role of plant/soil microbiomes – especially that of legumes in immune response and other physiological functions – was discussed in detail.

During the workshops, plans for joint research of ICRISAT and the Vienna Metabolomics Center were disclosed. The aim is to study drought tolerance in chickpea and analyze the two-line hybrid system and epigenomics for hybrids in pigeonpea. This study will use models to predict higher-order relationships between molecular phenotypes, interactions among each other and subsequent influence on complex traits.
