Pathogen invasion at one site in a plant triggers defensive reactions throughout the rest of the plant. This systemic acquired resistance (SAR) is mediated by salicylic acid and the regulatory protein NPR1 and involves the activation of a suite of pathogenesis-related genes. Wang et al.

Optimal plant defense should incorporate any mechanisms that influence the feeding behavior of potential pests. From a diverse collection of examples suggesting that the defense of a plant may be improved in the company of specific neighbors, we discuss a framework of operational mechanisms that begin to clarify some aspects of the recognized influence

In order to resist herbivore attack, plants use direct defenses, such as toxins and digestibility reducers, as well as indirect defenses that affect components of the plants' community (such as natural enemies and diseases). Plant defenses can be expressed constitutively or produced in response to an attacking pathogen or herbivore ...

Surface lipids and plant defenses
Plant Physiology and Biochemistry, 2009The major function of the plant epidermis is to form the cuticle, a functional permeability barrier of the cell wall which prevents excessive water loss and the entry of harmful substances and pathogens into the host. This type of cell wall modification is mainly composed of a polyester matrix, cutin, and soluble waxes embedded in the matrix and ...

Plants respond to pathogen attack by recognizing molecular signals from the invaders and instigating their own cellular responses to limit damage. Shen et al . now show that two of the plant’s defense systems themselves interact at the level of gene transcription.

Systemic signaling during plant defense
Current Opinion in Plant Biology, 2013Systemic acquired resistance (SAR) is a type of pathogen-induced broad-spectrum resistance in plants. During SAR, primary infection-induced rapid generation and transportation of mobile signal(s) 'prepare' the rest of the plant for subsequent infections. Several, seemingly unrelated, mobile chemical inducers of SAR have been identified, at least two of

Plant Defense and Antimicrobial Peptides
Protein & Peptide Letters, 2005Plants are constantly exposed to a large array of pathogenic organisms and the survival in these conditions demands quick defense responses which include the synthesis of defense peptides and proteins with antimicrobial properties. The main groups of antimicrobial peptides found in plants are thionins, defensins and lipid transfer proteins.

Plant immunity and plant defense
This chapter summarizes the current knowledge on how plants defend against pathogen invasion and proliferation by structural and biochemical defense measures. To this end, it recapitulates the genetic basis of plant immunity and susceptibility to diseases.Hückelhoven, Ralph, Schouten, Alexander

Plants are compelled to withstand stresses of all kinds, be it biotic, abiotic or anthropogenic as a consequence of their immobility. The initial infection process involving adhesion/recognition events between plants and fungal pathogens is essential for the establishment of pathogenesis.

Plant–microbe interactions: plants modulating their defenses
Trends in Plant SciencePlant immunity is mediated by multiple factors, including microbial interactions and gene expression. Keppler et al. identified a set of microbe-responsive genes (general non-self response genes) whose expression or products affect bacterial strain abundance and enhance immunity. We explore how these genes shape alternative plant defense strategies for
