Omics studies of the priming phenomenon

Follow us in twitter : @pibgroupIR

Along with evolution plants have developed defensive strategies to survive the attackers. Plants that have been exposed to contact with necrotizing pathogens, insects or appropriated treatments can mount rapidly a stronger defence once the second wave of stress is presented. This is known as plant memory and also as priming, which is based in an adaptation of the plant that reacts faster and stronger against a given pathogen or stress, generating an effective defence. Our current research is mostly focused on omics studies (mainly metabolomics) of the priming phenomenon from several points of view. In the first place, we try to understand whether plants exposed different priming stimuli activated a shared molecular fingerprint or, on the opposite, each priming inducer has its own characteristic mechanisms. In this approach we study the mechanisms behind β-aminobutyric acid (BABA)-induced resistance, mycorrhizae-induced resistance (MIR) and constitutive priming released.
In addition, we have recently set up a promising research line focused on citrus innate immunity against arthropods.
