MODULATORS OF THE DEVELOPMENT OF MYCHORRIZAL FUNGI WITH ARBUSCULES, AND USES THEREOF

摘要

The invention relates to the identification of compounds, i.e. strigolactones, which are able to stimulate the growth and/or development of mychorrizal fungi with arbuscules (MA fungus). Said compounds are, for example, natural strigolactones such as strigol, alectrol, sorgolactone, orobanchol, or the synthetic analogs GR7, GR24, Nijmegen-1, demethylsorgolactone. The invention opens up new pathways for the development of a type of agriculture which is more respectful of the environment, particularly in that it enables the implementation, on a large or small scale, of advanced mychorrization techniques designed to increase the production of fungic inoculum, the use of MA fungi in soils or cultivation media and to intensify symbiotic interaction between said micro-organisms and cultivated plants.
