Update on crosstalk between salicylic acid and jasmonate in defense signaling: a proteomic approach

Abstract: The natural protection of plants against microbial invaders and chewing insects is
based on both pre-existing and inducible defence systems that provide protection against a broad range of potential pathogens. Activation of plant defense mechanisms is associated with ecological fitness costs, so plants need regulatory mechanisms to effectively and efficiently adapt to changes in their complex environment. Crosstalk between hormonal signaling pathways may have evolved to allow plants to fine-tune the induction of their defense in response to different plant pathogens. In this paper we report on a proteomic approach to unravel the crosstalk between salicylic acid and jasmonate in the onset of resistance in Arabidopsis.
