“…For instance, the anthocyanin delphinidin present in seed coats of peas is exuded during germination and has a fungistatic activity against conidial germination of F. solani , but this activity is nulled by a sufficient exudation of carbohydrates at the same time (Kraft, ). Li et al () assessed the effect of root exudates of peanut cultivars on different pathogenic fungi and generally observed a stimulation of fungal growth at intermediate concentrations of exudates. However, the stimulation decreased with higher concentrations of exudates, suggesting that the root exudates contained antimicrobial substances along sugars and amino acids.…”

Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple pathogens in field situations. Novel tools allow to decipher plant-microbiome interactions in unprecedented detail and provide insights into resistance mechanisms that consider both simultaneous attacks of various pathogens and the interplay with beneficial microbes. Although it has become clear that plant-associated microbes play a key role in plant health, a systematic picture of how and to what extent plants can shape their own detrimental or beneficial microbiome remains to be drawn. There is increasing evidence for the existence of genetic variation in the regulation of plant-microbe interactions that can be exploited by plant breeders. We propose to consider the entire plant holobiont in resistance breeding strategies in order to unravel hidden parts of complex defence mechanisms. This review summarizes (a) the current knowledge of resistance against soil-borne pathogens in grain legumes, (b) evidence for genetic variation for rhizosphere-related traits, (c) the role of root exudation in microbe-mediated disease resistance and elaborates (d) how these traits can be incorporated in resistance breeding programmes.

“…Plant–microbe contact can be roughly classified into two types, compatible and incompatible interactions, leading to the critical agronomic phenotypes of susceptibility and resistance to certain diseases, respectively. The incompatible interaction is extensively exploited by crop breeders to raise resistant cultivars for crop production in agriculture (Li et al 2013). …”

Chitin is the second abundant polysaccharide in the world after cellulose. It is a vital structural component of the fungal cell wall but not for plants. In plants, fungi are recognised through the perception of conserved microbe-associated molecular patterns (MAMPs) to induce MAMP-triggered immunity (MTI). Chitin polymers and their modified form, chitosan, induce host defence responses in both monocotyledons and dicotyledons. The plants’ response to chitin, chitosan, and derived oligosaccharides depends on the acetylation degree of these compounds which indicates possible biocontrol regulation of plant immune system. There has also been a considerable amount of recent research aimed at elucidating the roles of chitin hydrolases in fungi and plants as chitinase production in plants is not considered solely as an antifungal resistance mechanism. We discuss the importance of chitin forms and chitinases in the plant–fungal interactions and their role in persistent and possible biocontrol.Abbreviations ET, ethylene; GAP, GTPase-activating protein; GEF, GDP/GTP exchange factor; JA, jasmonic acid; LysM, lysin motif; MAMP, microbe-associated molecular pattern; MTI, MAMP-triggered immunity; NBS, nucleotide-binding site; NBS-LRR, nucleotide-binding site leucine-rich repeats; PM, powdery mildew; PR, pathogenesis-related; RBOH, respiratory burst oxidase homolog; RLK, receptor-like kinase; RLP, receptor-like protein; SA, salicylic acid; TF, transcription factor.

“…Wang et al (2009) found that RPW8.2, an atypical R protein showing homology to the CC domain of an ancient clade of CNLRs (Xiao et al 2001;Collier et al 2011) is specifically targeted to the EHM where it activates host defenses including enhanced formation of the haustorial encasement and accumulation of H 2 O 2 in the host-pathogen interface. Subsequent large-scale mutational analyses revealed two basic residue-enriched short motifs in RPW8.2 to be essential for EHM-specific localization (Wang et al 2013), implying that an EHM-oriented polar secretory pathway is engaged for delivering vesicles carrying RPW8.2 to the EHM (Figure 1 ). Interestingly, a recent study showed that VAMP721/722-specified vesicles are also responsible for sending RPW8.2 to the EHM (Kim et al 2014).…”

“…The cell surface‐localized pattern‐recognition receptors (PRRs) recognize pathogen/microbe‐associated molecular patterns (P/MAMP) as non‐self molecules shared by a class of microbes and subsequently activate immune responses termed P/MAMP triggered immunity (PTI or MTI) (Chisholm et al ; Jones and Dangl ; Boller and Felix ). PTI acts as basal defense to protect plants from the invasion of most potential pathogenic microbes and major defense responses in PTI includes ion fluxes increase, mitogen‐activated protein kinases (MAPKs or MPKs) signaling cascades activation, reactive oxygen species (ROS) production, defense‐related gene activation and callose deposition (Li et al ). Adapted pathogens subvert PTI by their effectors delivered into host cells, thereby establishing parasitism.…”

Plants have evolved a sophisticated immune system to fight against pathogenic microbes. Upon detection of pathogen invasion by immune receptors, the immune system is turned on, resulting in production of antimicrobial molecules including pathogenesis-related (PR) proteins. Conceivably, an efficient immune response depends on the capacity of the plant cell's protein/membrane trafficking network to deploy the right defense-associated molecules in the right place at the right time. Recent research in this area shows that while the abundance of cell surface immune receptors is regulated by endocytosis, many intracellular immune receptors, when activated, are partitioned between the cytoplasm and the nucleus for induction of defense genes and activation of programmed cell death, respectively. Vesicle transport is an essential process for secretion of PR proteins to the apoplastic space and targeting of defense-related proteins to the plasma membrane or other endomembrane compartments. In this review, we discuss the various aspects of protein trafficking during plant immunity, with a focus on the immunity proteins on the move and the major components of the trafficking machineries engaged.
