Análisis de metabolitos de tomate alterados en la ruta del ácido jasmónico durante la simbiosis micorrízica con Rhizophagus irregularis. by Dabdoub González, Nicole

“…ABSTRACT: In the following project the impact on metabolic fluxes in roots is assessed, as well as the growth and nutrition effects originated during the mycorrhizal symbiosis between Rizophagus irregularis and tomato plants (Solanum lycopersicum cv Castelmart) with altered jasmonic acid (JA) levels through mass spectrometry analysis and metabolic profiling. Three genetic backgrounds were used: wild-type (WT), transgenic line (PS) with overproduction of JA and mutants (spr2) with JA deficiency. …”
