SPS - Saclay Plant Sciences

Idex Paris-Saclay Prematuration call: very good results for the SPS teams!

Université Paris-Saclay

The Idex Paris-Saclay Prematuration call aims to support the emergence of projects with high socio-economic potential (https://www.universite-paris-saclay.fr/en/node/11531).

 

The project leaders, assisted by the Paris-Saclay University and the Paris-Saclay Technology Transfer Acceleration Company (SATT), make the most of the time and funds allocated to their project in order to 1) produce a study of its economic and legal potential and, if relevant, a valorization strategy, 2) develop the proof of concept and finally 3) propose a team for the project maturation and development.

Out of the 159 projects selected since the Idex Paris-Saclay Prematuration call was created, 10 projects are led by SPS members, of which 4 are funded via the LabEx, which has contributed financially to the last two calls.

Development of a synthetic strigolactone formulated to control tomato branching (ANASTRIFOR)

Coordination: François-Didier Boyer

Project selected in 2013

The aim of this project is to develop an effective formulation for applying a strigolactone analogue in order to control tomato ramification for a better productivity. Formulations, doses and timing of applications will be validated on pea, for which the proposing team has a high expertise and for which the active principle has shown a great efficiency, and will be transferred to tomato.

 

Heat stress on wheat and modification of the redox proteome: to the creation of new tools for plant breeding (EchauBlé)

Coordination: Emmanuelle Issakidis-Bourguet

Project selected in 2013

Temperature strongly affects the yield and composition of small grain cereals. With global warming, heat stress has been occuring on wheat in a worrying way for a decade in France. We propose to explore the implication of redox modifications of the wheat proteome in the response to heat stress, with the aim of creating new tools for plant breeding.

 

Development of a micro-press for extraction and analysis of plant oils (MICROPRESSE)

Coordination: Jean-Denis Faure

Project selected in 2013

The aim of the microPress project is to develop the pressing of small quantities of oil seeds (rapeseed, camelina) thanks to an original press concept based on the extraction of oil by centrifugation. This technology will overcome the shortcomings of current systems and eventually have sufficient flow to simultaneously analyze a large number of seed lines and / or batches. This tool, which has already been validated by a feasibility study, will be operationally implemented and a market study will be carried out among stakeholders in the oil and protein crops sector with the aim of monitoring and evaluating the quality / quantity of oil from lots of seeds, plants.

 

Dying To Resist (MPR)

Coordination: Moussa Benhamed

Project selected in 2014

The induction of localized cell death is one of the most notable resistance mechanisms that allows plant to fight virus infection by confining tham in a few hundred cells around their entry point. Buiding on our recent results on programmed cell death (PCD), we propose to improve the plant resistance to virus by counteracting a viral strategy inhibiting PCD both in the model plant Arabidopsis thaliana and crops such as tomato and melon.

 

Identification of chemical promoters of caulogenesis (PHARMA-CAULOGENÈSE)

Coordination: Pierre Hilson

Project selected in 2014

The objective of the project is to identify molecules that promote organogenesis in plant tissues cultivated in vitro, which is a key step for breeding, micropropagation and genetic transformation of major crops. The compounds that were tested are known inhibitors of mitochondrial functions. We have shown that certain compounds improve the regeneration rate in tissues of the model species Arabidopsis thaliana. Outside the project framework, these results were confirmed in agricultural species in collaboration with other research groups.

 

BOost Simultaneously Seed vigor and conservation (BOSS)

Coordination: Loïc Rajjou

Project selected in 2016

The agricultural success of an area heavily depends on the quality of seed production and seed performance in the field. Seed priming is widely used by seed technologists to enhance seed vigor, in terms of germination potential, and to increase stress tolerance to penalizing environment, but affects seed storability and longevity. The BOSS project proposes a new method of seed priming, based on knowledge of the physiology of germination, to improve the seed vigor and longevity of primed seeds.

 

Obtaining plants with high-energy, high-growth and high resistance to environmental stress (EnergyCrop)

Coordination: Bertrand Gakière

Project selected in 2016

We have developed in the model plant Arabidopsis thaliana a method for obtaining fast growing plants, having a greater biomass, a 50% increased seed yield, increased resistance to environmental stress and better germination capacity. This method relies on overproducing a key-enzymatic step for the production of an energy metabolite essential for plant metabolism. The project is to validate this process in plants of agronomic interest.

 

Therapeutic potential of peptide inhibitors of N-myristoyltransferase (MyrAge)

Coordination: Thierry Meinnel

Project selected in 2016

Depending on the cell context considered, NMT specific inhibition displays anti-infectious or anticancer properties. Large scale approaches have allowed us to identify a series of potent inhibitors of NMT. This project is to validate the concept that the series has indeed a strong therapeutic potential. The proposed study combines in vitro and in cellulo approaches in order to fully characterize the series and its physiological

targets, initiate a pharmacological analysis and to finally file a patent.

 

Heat stress in wheat and modification of the redox proteome: for the creation of new crop selection tools (EchauBlé 2)

Coordination: Emmanuelle Issakidis-Bourguet

Project selected in 2017

Temperature strongly impacts crop production yield and composition of small grain cereals. With global warming, exposure to high temperatures has become a major concern for French wheat breeders. Here, we propose to validate the implication of redox proteome modifications in wheat response to heat stress, with the goal to create new tools toward development of “climate-smart” wheat varieties.

 

Improvement of protein concentration in plants (APPLE)

Coordination: Fabien Chardon

Project selected in 2017

In order to file a patent to increase the protein concentration of plants, the APPLE project aims to provide the proof of concept in a cultivated species of a biotechnological solution discovered in a model species that modifies the nitrogen pools promoting the nitrogen use efficiency of nitrogen utilization and the protein production in the seeds.
