Roles of Plant-Specific Inserts in Plant Defense
Trends in Plant Science, 2020Ubiquitously expressed in plants, the plant-specific insert (PSI) of typical plant aspartic proteases (tpAPs) has been associated with plant development, stress response, and defense processes against invading pathogens. Despite sharing high sequence identity, structural studies revealed possible different mechanisms of action among species.

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 ...

Plant peptides in defense and signaling
Peptides, 2014This review focuses on plant peptides involved in defense against pathogen infection and those involved in the regulation of growth and development. Defense peptides, defensins, cyclotides and anti-microbial peptides are compared and contrasted. Signaling peptides are classified according to their major sites of activity. Finally, a network approach to

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

Belowground Herbivory and Plant Defenses
Annual Review of Ecology, Evolution, and Systematics, 2009Belowground-feeding herbivores may be very destructive to plants. Roots are known to produce various defense compounds to protect themselves against these herbivores, both with direct and indirect—inducible—defense compounds. Recent literature reviews reveal no overall pattern for root-shoot defense allocation.

Macroevolution of plant defense strategies
Trends in Ecology & Evolution, 2007Theories of plant defense expression are typically based on the concepts of tradeoffs among traits and of phylogenetic conservatism within clades. Here, I review recent developments in phylogenetic approaches to understanding the evolution of plant defense strategies and plant-herbivore coevolutionary interactions.

Induced Chemical Defense in Plants
Angewandte Chemie International Edition, 1998Surprising parallels exist between the chemical defense mechanisms of plants and animals. The biosynthesis of defensive substances in plants can be induced by microbial or herbivoral attack. Recent results demonstrate that the chemical defense of plants is mediated by lipid-based signaling systems.

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

General Mechanisms of Plant Defense and Plant Toxins
2016Long before the appearance of flowering plants, early plants were infected by pathogenic microorganisms and challenged by herbivorous animals. Consequently, plants and animals evolved defenses and counter-defenses from the very beginning. Therefore, to cope with a huge diversity of unfavorable biotic conditions, plants developed several different ...
