    The Plant Primary Cell Wall is critical to plant cell growth, differentiation, and response to biotic and abiotic stress. It should be remembered that the appearance of any induced change to the “basal” biology of higher plants is ultimately manifested within the plant Primary cell wall matrix. This section of my research involves alterations to the primary cell wall following the abiotic (chemical) induction of systemic acquired resistance (SAR). This is the activation of plant defenses in unaffected areas of the plant, which gradually spreads throughout the entire plant, resulting in a long-lasting unspecific immunization against viruses, bacteria and fungi. A typical induced resistance results in the ligninification of plant material, the expression of many types of proteins, the activation and induction of anodic peroxidase isozymes, and the chemical alteration of the structural carbohydrates of the plant primary cell wall.

    Project Outline

    We are going to investigate many different aspect of the induction of SAR in tomato seedlings by the application of Salicylic acid (SA) onto cotyledons and study the alterations produced in the real leaves. Our main goal is to determine the timing of events which lead to the induction of SAR.
