Bio/Research

The overall goal in the Cameron lab is to elucidate and understand the signal transduction pathways that lead to, and the processes responsible for, induced resistance in plants to microbial infection, including Systemic Acquired Resistance (SAR) and Age-related Resistance (ARR), using molecular genetics, plant pathology, physiology, biochemistry, genomics and cell biology. ARR is a form of resistance that develops in mature Arabidopsis thalianaplants in response to Pseudomonas syringae pv. tomato (Pst) infection. Unlike ARR, SAR is elicited in response to certain necrotizing infections in one part of a plant resulting in production of a long distance signal and subsequent resistance to virulent infections in distant tissues. Studies in our lab demonstrate that salicylic acid (SA) accumulation in the plant cell wall is important for the ARR response and that SA may be acting as an anti-microbial agent against Pst. SA is no longer thought to be the long distance signaling molecule in SAR. Work in our lab using dir1-1, a SAR-defective mutant, indicates that DIR1, a putative lipid transfer protein, is involved in long distant signaling to establish SAR in distant tissues.
