Special Issue Information

Dear Colleagues,

The World population's diet is mainly based on crop production. Fungi are one of the most important microorganisms affecting the quantity and quality of such crops. Increasing worldwide concern about food production and safety has enhanced interest in fungal–plant interactions and mycotoxin production in food products. Furthermore, given their economic importance, an increasing number of studies on fungal pathogens that interact with fruit trees and commercial ornamental plants have been seen as of late.

For this reason, this Special Issue, entitled “Pathogenic Fungal–Plant Interactions”, seeks the submission of manuscripts exploring advancements in and providing reviews of pathogenic fungi that interact with cultivable plants, with a view to integrating production and food safety. Topics of interest include, but are not limited to, the following: physiological and molecular interactions (cultivable and model plants), detection of fungal pathogens, control strategies, disease management, interactions of plant–fungal pathogens with the environment, mycotoxins, and plant resistance.

Cereal crops are affected by one of the most devastating diseases worldwide, known as Fusarium head blight (FHB), with Fusarium graminearum being the most isolated causal pathogen. Another species associated with this disease is Fusarium poae. This species has been considered a relatively weak pathogen compared to F. graminearum, but its importance has increased due to its occurrence in cereal grains worldwide. Considering the advantages of using B. distachyon as a plant model and the importance of F. poae in crops, our study aimed to evaluate the potential use of Brachypodium as a plant model to evaluate the compatible interaction with F. poae. Twelve Brachypodium spp. accessions from different countries were inoculated with a selected F. poae set of isolates. Disease severity, conidial quantification, fungal DNA biomass, and nivalenol quantification were assessed. The results showed a compatible interaction between Brachypodium accessions and Fusarium poae, which allowed the use of the model plant for future plant–pathogen interaction studies. Full article

Carbohydrate-binding modules (CBMs) are essential virulence factors in phytopathogens, particularly the extensively studied members from the CBM50 gene family, which are known as lysin motif (LysM) effectors and which play crucial roles in plant–pathogen interactions. However, the function of CBM50 in Tilletia horrida has yet to be fully studied. In this study, we identified seven CBM50 genes from the T. horrida genome through complete sequence analysis and functional annotation. Their phylogenetic relationships, conserved motifs, promoter elements, and expression profile were further analyzed. The phylogenetic analysis indicated that these seven ThCBM50 genes were divided into three groups, and close associations were observed among proteins with similar protein motifs. The promoter cis-acting elements analysis revealed that these ThCBM50 proteins may be involved in the regulation of the phytohormones, stress response, and meristem expression of the host plant during T. horrida infection. The transcriptome data indicated that four ThCBM50 genes were upregulated during T. horrida infection. We further found that ThCBM50_1 caused cell death in the leaves of Nicotiana benthamiana, and its signal peptide (SP) had a secreting function. These results offer important clues that highlight the features of T. horrida CBM50 family proteins and set the stage for further investigation into their roles in the interactions between T. horrida and rice.
