Summary: The recognition of invasion patterns (IPs) is crucial for the establishment of defense reactions in plants against pathogens. While the perception of chitooligosaccharides (COS) in grapevine is poorly understood, it has been well described in the model plant Arabidopsis thaliana. By overexpressing the two putative AtLYK5 orthologs from grapevine in Arabidopsis, VvLYK5-1 was found to mediate the perception of chitin but not chitosan oligomers.

Summary: The study identified a novel EIX-like protein, VdEIX3, from V. dahliae, which induces immunity in Nicotiana benthamiana. NbEIX2, a leucine-rich repeat receptor-like protein, regulates the perception of VdEIX3 in N. benthamiana. These findings suggest potential applications of NbEIX2 in transgenic breeding for enhancing resistance to Verticillium wilt diseases.

Summary: Plant microbiome structure is influenced by plant health and productivity. The study found that MAMP-detecting PRRs have little effect on the structure of endophytic bacterial and fungal microbiomes in the field, suggesting that individual PRRs are not critical in shaping the plant microbiome.

Summary: A study found that the allotetraploid Solanaceae plant Nicotiana benthamiana has two closely related receptor-like proteins (RLPs), NbEIX2 and NbRXEG1, which regulate the recognition of VdEIX3 and PsXEG1. It was also discovered that NbRXEG1 participates in VdEIX3 recognition. Phylogenetic analyses showed that NbEIX2 and NbRXEG1 were obtained from different diploid ancestors by hybridization. This study provides a new model for understanding defense mechanisms in allopolyploid plants.

Summary: Research shows that MAMPs and DAMPs affect root growth and development, and PEP1 has been demonstrated to suppress root growth and promote root hair formation. PEP1 influences cell division in the vascular tissue and differentiation of xylem cells, with changes linked to symplastic blockage triggered by PEP1.

Summary: Human genetic control plays a significant role in Mycobacterium tuberculosis infection outcomes, with genetic variation affecting immunoreactivity and tuberculosis disease. Pattern recognition receptors (PRRs) help facilitate the interaction between humans and Mtb, although they are less critical for infection outcomes compared to effector molecules like IFN-gamma. Redundancy in the innate immune system may contribute to PRRs playing a more subtle role in limiting the pathogen.

Summary: This study investigates the association between the initial leaf polyphenolic composition and the susceptibility of grapevine to downy mildew. The research finds that the diverse genetic background of Croatian grapevine germplasm leads to different reactions to the infection of Plasmopara viticola. The initial constitutive polyphenolic composition of the leaves has a crucial influence on their susceptibility to the pathogen, which can be utilized in grapevine breeding programs.

Summary: Mechanical ventilation is commonly used in ICU patients, but may lead to ventilator-induced lung injury (VILI). The pathogenesis of VILI involves inflammatory mediators, damage-associated molecular patterns, and pattern recognition receptors. Therefore, blocking these signaling pathways may help reduce the progression of VILI.

Summary: The study found that there are biological differences between the inner and outer mesocarp tissues of grape berries, which affect the acceptance of consumers. The inner mesocarp of harder berries is softer than the outer tissue, and an increased abundance of cell wall monosaccharides was observed at harvest. Additionally, differences in homogalacturonan methylesterification and cell wall calcium were found between soft and hard berries.

Summary: Flavescence doree (FD) phytoplasma from 16SrV-C and -D subgroups cause severe damage to grapevines throughout Europe. European black alder and clematis serve as perennial plant reservoirs for 16SrV-C phytoplasma strains, and their host range has recently been extended to hazelnuts. The decline of hazelnut orchards in Slovenia is attributed to 16SrV phytoplasma infections, possibly transmitted by the non-autochthonous leafhopper Orientus ishidae.

Summary: The root system is crucial for plant development and response to stresses, but it is challenging to study due to limited visualization. This study evaluated different growing methods for grapevine cuttings and utilized various imaging techniques for root visualization and quantification. Neutron tomography was found to be effective in quantifying root volume, and an automated image analysis method was developed for identifying adventitious roots in rhizotrons.

Summary: The study revealed that pea is more susceptible to Aphanomyces euteiches infection compared to faba bean. Pea root exudates showed attraction towards the pathogen, while faba bean exudates exhibited a repellent effect. The research suggests that early belowground defense plays a critical role in host susceptibility to root rot, opening new perspectives for disease management.

Summary: Plant innate immunity is activated by lipidic secretome from opportunistic pathogen Pseudomonas aeruginosa, including rhamnolipids and hydroxy fatty acids, through distinct mechanisms. While hydroxy fatty acids are sensed by a specific receptor kinase in plants, rhamnolipids trigger an atypical immune response independently of this receptor. The immune response triggered by rhamnolipids is influenced by the sphingolipid composition of the plasma membrane.

Summary: In the past, grapevine trunk diseases (GTDs) were controlled by treatments with sodium arsenite, but due to its banning, effective methods for GTDs management are lacking. This study investigates the effect of sodium arsenite on woody tissues, revealing its impact on both plant metabolome and structural barriers. The findings suggest that sodium arsenite stimulates plant secondary metabolites in wood, enhancing its fungicide effect and influencing phytotoxin patterns. This study contributes to a better understanding of the mode of action of sodium arsenite, aiding the development of sustainable strategies for GTDs management.

Summary: Chitosan, known for its antimicrobial and antifungal properties, loses bioactivity when sprayed in open fields, possibly due to sunlight. This study investigated the effects of UV radiation on chitosan stability. Although minor differences were observed, no clear structural modifications of chitosan were detected. Interestingly, irradiated chitosan samples maintained their bioactivity, contradicting the assumption that sunlight decreases chitosan effectiveness in open field conditions.

Summary: A straightforward method for synthesizing carbohydrate templated isoxazolidines using microwave activation is described. The reaction involves the interaction of unprotected glycosylhydroxylamines with methyl acrylate, resulting in the formation of rhamno- and erythro-isoxazolidines. These compounds are recognized by plant cells, triggering a strong immune response and exhibiting high antifungal activity against Botrytis cinerea.

Summary: Esca is a complex grapevine trunk disease caused by wood-rotting fungi, with inconsistent foliar symptoms influenced by environmental, physiological, and genetic factors. Clonal and year-dependent metabolic responses to the disease were observed, showing different metabolite fingerprints and symptom expression between Chardonnay and Trousseau clones. Possible relationship with rainfall and higher susceptibility of certain clones were also identified.
