“…Nevertheless, neither RGD peptides nor eATP are the expected ligands for this L-LecRLK. Instead, cell wall-derived molecules or glycoproteins have been suggested to be the bona fide ligands based on in silico modelling of LecRKI.9 ED (Bellande et al, 2017). These data suggest that LecRKI.9 and/or other L-Lec-RLKs might be implicated in the perception of as-yet-unknown cell wall-derived DAMPs.…”

“…LysM domains are widespread in eukaryotic and prokaryotic proteins, and are typically implicated in the recognition of N-acetylglucosamine (GlcNAc)-containing glycans (Buist et al, 2008;Bellande et al, 2017). LysM-PRRs have been described in various plant species as receptors for MAMPs such as chitin and PGN, both in symbiotic and pathogenic interactions (Zipfel and Oldroyd, 2017).…”

“…Lectins are widespread carbohydrate-binding proteins that can bind mono-and oligosaccharides (Bellande et al, 2017). Plant Lec-RLKs comprise PRRs with lectin-type extracellular domains that have been divided into three subclasses: (i) G-(GNA-related or S-locus) lectins; (ii) C-(calcium-dependent) lectins; and (iii) L-(legume) lectins (Wang and Bouwmeester, 2017).…”

“…It is worth highlighting Dectin-1, the mammalian b-glucan receptor, which was the first mammalian non-Toll-like receptor discovered that is capable of coupling microbial recognition with transcriptional regulation of genes ( Figure 3; Brown and Gordon, 2001;Dambuza and Brown, 2015;Wang and Bouwmeester, 2017). In plants, Lec-RLKs have a prominent role in biotic stress responses (Bouwmeester et al, 2011;Desclos-Theveniau et al, 2012;Singh et al, 2012;Wang et al, 2012Wang et al, , 2014Gouhier-Darimont et al, 2013;Huang et al, 2013;Balague et al, 2017), in contrast to their minor role in developmental processes (Bellande et al, 2017). However, only two ligand-LecRLK pairs have been identified (Bellande et al, 2017;Wang and Bouwmeester, 2017): lipopolysaccharides (LPSs)-LORE and extracellular ATP (eATP)-DORN1.…”

Plant cell wall‐mediated immunity: cell wall changes trigger disease resistance responses

et al. 2018

Plants have evolved a repertoire of monitoring systems to sense plant morphogenesis and to face environmental changes and threats caused by different attackers. These systems integrate different signals into overreaching triggering pathways which coordinate developmental and defence-associated responses. The plant cell wall, a dynamic and complex structure surrounding every plant cell, has emerged recently as an essential component of plant monitoring systems, thus expanding its function as a passive defensive barrier. Plants have a dedicated mechanism for maintaining cell wall integrity (CWI) which comprises a diverse set of plasma membrane-resident sensors and pattern recognition receptors (PRRs). The PRRs perceive plant-derived ligands, such as peptides or wall glycans, known as damage-associated molecular patterns (DAMPs). These DAMPs function as 'danger' alert signals activating DAMP-triggered immunity (DTI), which shares signalling components and responses with the immune pathways triggered by non-self microbe-associated molecular patterns that mediate disease resistance. Alteration of CWI by impairment of the expression or activity of proteins involved in cell wall biosynthesis and/or remodelling, as occurs in some plant cell wall mutants, or by wall damage due to colonization by pathogens/pests, activates specific defensive and growth responses. Our current understanding of how these alterations of CWI are perceived by the wall monitoring systems is scarce and few plant sensors/PRRs and DAMPs have been characterized. The identification of these CWI sensors and PRR-DAMP pairs will help us to understand the immune functions of the wall monitoring system, and might allow the breeding of crop varieties and the design of agricultural strategies that would enhance crop disease resistance.

Plant resistance in different cell layers affects aphid probing and feeding behaviour during poor- and non-host interactions

Aphids are phloem-feeding insects that cause economic losses to crops globally.Whilst aphid interactions with susceptible plants and partially resistant genotypes have been well characterised with regards to aphid probing and feeding behaviour, the interactions with non-natural host species are not well understood. Using aphid choice assays with the broad host range pest Myzus persicae and the cereal pest Rhopalosiphum padi we show that about 10% of aphids settle on non-/poor-host species over a 24h time period. We used the Electrical Penetration Graph technique to assess aphid probing and feeding behaviour during the non-/poor-host interactions. In the Arabidopsis non-host interaction with the cereal pest R. padi aphids were unable to reach and feed from the phloem, with resistance likely residing in the mesophyll cell layer. In the barley poor-host interaction with M. persicae, resistance is likely phloem-based as aphids were able to reach the phloem but ingestion was reduced compared with the host interaction. Overall our data suggests that plant resistance to aphids in non-host and poor-host interactions with these aphid species likely resides in different plant cell layers. Future work will take into account specific cell layers where resistances are based to dissect the underlying mechanisms and gain a better understanding of how we may improve crop resistance to aphids.

Plant Lectins: Implications in Tolerance and Resistance

Lectins are ubiquitous classes of carbohydrate‐binding proteins. They serve a wide range of physiological functions in Phyto‐organisms. Among many biological significances, they play a crucial role in plant tolerance and resistance against environmental biotic and abiotic challenges. They are a component of the plant's innate immune system and defence mechanism. Lectin‐like receptor kinases (Lec‐RLK) are essential in stress sensing and saccharide signalling. Their expression can be modulated by various hormonal responses; they can also tweak downstream hormonal pathways or signal the expression of stress‐related genes. Other plant lectin families, localized in the vacuole, cytoplasm, and nucleus, could also revamp the response to different stress factors. They participate in the further downstream responses, including the clearance and turnover of accumulated undesired and misfolded nascent proteins triggered by stress, DNA protection, and chromatin modulation. Understanding the genetics, the evolution of gene mechanisms, and the functional roles of Lectins in molecular pathways affecting plant tolerance is essential to reduce the effects of global climate change on food security and the health and well‐being of humans. This review will assist in integrating existing knowledge, with a focus on understanding how plant lectins confer adaptation to challenging environmental conditions, ultimately to assist agricultural scientists in breeding plants with greater adaptive capacities.
