Breeding resistant crops is key to achieving this goal, which is an effort requiring collaboration among stakeholders, scientists, breeders, farmers, and policymakers. During a disease outbreak, epidemiologists survey the occurrence of a disease after which pathologists investigate mechanisms to stop an infection. Policymakers then implement strategies with farmers and breeders to overcome the outbreak. Information flow from the field to the lab and back to the field involves several processing hubs that require different information inputs. Failure to communicate the necessary information results in the transfer of meaningless data. Here, we discuss gaps in information acquisition and transfer between the field and laboratory. Using rice bacterial blight disease as an example, we discuss pathogen biology and disease resistance to point out the importance of reporting pathogen strains that caused an outbreak to optimize the deployment of resistant crop varieties. We examine differences between infection in the field and assays performed in the laboratory to draw awareness of possible misinformation concerning plant resistance or susceptibility. We discuss key data considered useful for reporting disease outbreaks, sampling bias, and suggestions for improving data quality. We also touch on the knowledge gap in the state-of-the-art literature regarding disease dispersal and transmission. We use a recent case study to exemplify the gaps mentioned. We conclude by highlighting potential actions that may contribute to food security and to closing the yield gap. [Formula: see text] Copyright © 2025 The Author(s).

Resistance to Fusarium head blight (FHB) in wheat is well studied and documented. However, resistance to Gibberella ear rot (GER) in maize is less understood, despite several similarities to FHB. In this review, we synthesize existing literature on the colonization strategies, toxin accumulation, genetic architecture, and potential mechanisms of resistance to GER in maize and compare it with what is known regarding FHB in wheat. There are several similarities in the infection and colonization strategies of F. graminearum in maize and wheat. We describe multiple types of GER resistance in maize and identify distinct genetic regions for each resistance type. We discuss the potential of phenylpropanoids for biochemical resistance to F. graminearum. Phenylpropanoids are well characterized, and there are many similarities in their functional roles for resistance between wheat and maize. These insights can be utilized to improve maize germplasm for GER resistance and are also useful for FHB resistance breeding and management. [Formula: see text] Copyright © 2025 The Author(s).

Tolerance is a promising trait for crop breeding, but its genetic basis has rarely been studied and remains poorly understood. Here, we reveal the genetic basis of leaf tolerance to the fungal pathogen Zymoseptoria tritici that causes the globally important septoria tritici blotch (STB) disease on wheat. Leaf tolerance to Z. tritici is a quantitative trait that was recently discovered in wheat by using automated image analyses that quantified the symptomatic leaf area and counted the number of pycnidia found on the same leaf. A genome-wide association study identified four chromosome intervals associated with tolerance and a separate chromosome interval associated with resistance. Within these intervals, we identified candidate genes, including wall-associated kinases similar to Stb6, the first cloned STB resistance gene. Our analysis revealed a strong negative genetic correlation between tolerance and resistance to STB, indicative of a trade-off. Such a trade-off between tolerance and resistance would hinder breeding simultaneously for both traits, but our findings suggest a way forward using marker-assisted breeding. We expect that the methods described here can be used to characterize tolerance to other fungal diseases that produce visible fruiting bodies, such as speckled leaf blotch on barley, potentially unveiling conserved tolerance mechanisms shared among plant species.

Genomic approaches, including long-read sequencing, genome assembly, and haplotype phasing technologies, have revealed critical insights into mating systems, genetic diversity, virulence evolution, and host adaptation. Population genomics studies have uncovered diverse reproductive strategies across different cereal rust species and geographic regions, highlighting the interplay between sexual recombination and asexual reproduction. Transcriptomics have begun to unravel the gene expression networks driving sexual reproduction, and complementary omics approaches such as proteomics and metabolomics offer potential insights into the underlying molecular processes. Despite this progress, many aspects of cereal rust sexual reproduction remain elusive. Integrating multiple omics approaches with advanced cell biology techniques can help address these knowledge gaps, particularly in understanding sexual reproduction and its role in pathogen evolution. This comprehensive approach will be crucial for developing more targeted and resilient crop protection strategies, ultimately contributing to global food security.

There are over 20 mapped loci in wheat that confer strong (gene-for-gene) resistance against this pathogen, but the corresponding genes in Z. tritici that confer virulence against distinct R genes remain largely unknown. In this study, we developed a rapid forward genetics methodology to identify genes that enable Z. tritici to gain virulence on previously resistant wheat varieties. We used the known gene-for-gene interaction between Stb6 and AvrStb6 as a proof of concept that this method could quickly recover single candidate virulence genes. We subjected the avirulent Z. tritici strain IPO323, which carries the recognized AvrStb6 allele, to ultraviolet (UV) mutagenesis and generated a library of over 66,000 surviving spores. We screened these survivors on leaves of the resistant wheat variety Cadenza in mixtures (soups) ranging from 100 to 500 survivors per soup. We identified five soups with a gain-of-virulence (GoV) phenotype relative to the IPO323 parental strain and re-sequenced 18 individual isolates, including four control isolates and two isolates lacking virulence, when screened individually. Of the 12 confirmed GoV isolates, one had a single nucleotide polymorphism (SNP) in the AvrStb6 coding region. The other 11 GoV isolates exhibited large (approximately 70 kb) deletions at the end of chromosome 5, including the AvrStb6 locus. Our findings demonstrate the efficiency of this forward genetic approach in elucidating the genetic basis of qualitative resistance to Z. tritici and the potential to rapidly identify other, currently unknown, Avr genes in this pathogen.

In barley, the impact of flagellin on inducible defense responses has not been fully described. Here, we report that the flagellin-derived flg22 peptide induces callose, reactive oxygen species (ROS) bursts, and differential expression of 2,603 genes in barley. Cultivated barley genotypes produce different amplitudes of flg22-induced ROS bursts, indicating genetic variation for microbe-associated molecular pattern responses. Association mapping revealed a region on chromosome 7 underlying variation in flg22-induced ROS bursts, which contains 12 flg22-induced genes. Genotypes with higher flg22 responses had higher induced resistance to Xanthomonas translucens pv. translucens (Xtt), the causal organism of bacterial leaf streak. The flg22 region of Xtt flagellin evades detection in both barley and Arabidopsis, and a single amino acid change can restore immunogenicity of the peptide. Together, this work underlines the effectiveness of the flagellin-triggered defenses in promoting barley resistance to Xtt, which evades recognition of the flg22 region in its host.

The wheat pathogen Zymoseptoria tritici is ubiquitous across most wheat production regions distributed across diverse climate zones. We explored the genetic architecture of thermal adaptation using a global collection of 411 Z. tritici strains that were phenotyped across a wide range of temperatures and then included in a genome-wide association study. Our analyses provided evidence for local thermal adaptation in Z. tritici populations worldwide, with a significant positive correlation between bioclimatic variables and optimal growth temperatures. We also found a high variability in thermal performance among Z. tritici strains from the same field populations, reflecting the high evolutionary potential of this pathogen at the field scale. We identified 69 genes putatively involved in thermal adaptation, including one high-confidence candidate potentially involved in cold adaptation. These results highlight the complex polygenic nature of thermal adaptation in Z. tritici and suggest that this pathogen is likely to adapt well when confronted with climate change.

NLRs include both conserved and rapidly evolving members; however, their evolutionary trajectory in crops remains understudied. Availability of crop pan-genomes enables analysis of the recent events in the evolution of this highly complex gene family within domesticated species. Here, we investigated the NLR complement of 26 nested association mapping (NAM) founder lines of maize. We found that maize has just four main subfamilies containing rapidly evolving highly variable NLR (hvNLR) receptors. Curiously, three of these phylogenetically distinct hvNLR lineages are located in adjacent clusters on chromosome 10. Members of the same hvNLR clade show variable expression and methylation across lines and tissues, which is consistent with their rapid evolution. By combining sequence diversity analysis and AlphaFold2 computational structure prediction, we predicted ligand-binding sites in the hvNLRs. We also observed novel insertion domains in the LRR regions of two hvNLR subfamilies that likely contribute to target recognition. To make this analysis accessible, we created NLRCladeFinder, a Google Colaboratory notebook, that accepts any newly identified NLR sequence, places it in the evolutionary context of the maize pan-NLRome, and provides an updated clade alignment, phylogenetic tree, and sequence diversity information for the gene of interest.
