Update on Biochemistry of Plant Volatiles Biochemistry of Plant Volatiles

Plants have a penchant for perfuming the atmosphere around them. Since antiquity it has been known that both floral and vegetative parts of many species emit substances with distinctive smells. The discovery of the gaseous hormone ethylene 70 years ago brought the realization that at least some of the compounds emitted may have physiological significance without any distinctive smell to humans....

Plant volatiles

Plant volatiles are the metabolites that plants release into the air. The quantities released are not trivial. Almost one-fifth of the atmospheric CO2 fixed by land plants is released back into the air each day as volatiles. Plants are champion synthetic chemists; they take advantage of their anabolic prowess to produce volatiles, which they use to protect themselves against biotic and abiotic ...

Petits textes pour grandes masses de données

When controlled, omnipresence of data can leverage a potential of services never reached before. We propose an user driven approach to take advantage of massive data streams. Our solution named Stream2Text rests on a personalized and continual refinement of data to generates texts (in natural language) that give in a tailored synthesis of relevant data. This textual stream enables monitoring by...

Condensés de textes par des méthodes numériques

Since information in electronic form is already a standard, and that the variety and the quantity of information become increasingly large, the methods of summarizing or automatic condensation of texts is a critical phase of the analysis of texts. This article describes Cortex a system based on numerical methods, which allows obtaining a condensation of a text, which is independent of the topic...
