PAX2GRAPHML: a python library for large-scale regulation network analysis using BioPAX

PAX2GRAPHML is an open-source Python library that allows to easily manipulate BioPAX source files as regulated reaction graphs described in.graphml format.

The concept of regulated reactions, which allows connecting regulatory, signaling and metabolic levels, has been used. Biochemical reactions and regulatory interactions are homogeneously described by regulated reactions involving substrates, products, activators and inhibitors as elements.
PAX2GRAPHML is highly flexible and makes it possible to generate graphs of regulated reactions from a single BioPAX source or by combining and filtering BioPAX sources.

 Supported by the graph exchange format .graphml, the largescale graphs produced from one or more data sources can be further analyzed with PAX2GRAPHML or standard Python and R graph libraries.

Xylella fastidiosa: new research avenues

Since the discovery of the first outbreak of Xylella fastidiosa in Corsica in 2015, INRA has focused its research on the development of technologies to accelerate detection and identification of the bacteria in France. Scientific progress concerning the vector insects and their interactions with the environment mark another phase in research. Models and detection tools are sent to the French authorities in charge of crisis management – the DGAL (French Directorate General for Food Safety) and ANSES (The French Agency for Food, Environmental and Occupational Health & Safety) – to improve preventive actions and adapt the prophylactic analyses and measures.

Weeds: To love or not to love?

The pretty cornflowers, poppies and thistles that brighten up fields can be a real headache for both farmers and our health. For 25 years, Bruno Chauvel has worked to understand how these weeds grow and how to control them as the use of synthetic herbicides falls.
