NITROPRIMING

Omics studies of the priming phenomenon Along evolution plants have developed defensive strategies to survive the attackers. Plants that have been exposed to a contact with necrotizing pathogens, insects or appropriated treatments can mount rapidly a stronger defence once a 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 of the priming phenomenon from several points of view. In a 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 by mutation is negative regulatory genes such as NRT2. In addition, we have recently set up a promising research line focused in citrus innate immunity against arthropods.
