Crown rot in wheat: pathogen biology, host responses, and management strategies - Stress Biology Crown rot (CR), caused by Fusarium pseudograminearum and related species, is a soil-borne disease threatening global wheat (Triticum aestivum) production, with yield losses exceeding 50% under severe infections. The rapid spread of CR in China, driven by straw retention policies and warming climates, highlights the need for interdisciplinary solutions. This review systematically integrates advances in CR research and addresses pathogen biology, host resistance, and sustainable management. Research on pathogen biology has clarified the distribution of major Fusarium species, the infection process, toxin profiles, mating types, and virulence factors. Host resistance to CR is quantitatively controlled, and through quantitative trait locus (QTL) mapping and omics-based approaches, several genes encoding transcription factors, receptor-like kinases and enzymes, signaling pathways and secondary metabolites involved in resistance have been identified. Advances in control strategies, including chemical and biological methods, as well as the application of nanotechnology, have shown promising results. The review also highlights future research directions, such as investigating the molecular mechanisms of pathogen-host interactions, identifying effectors and susceptibility genes for CR in wheat, and integrating multi-omics studies with high-resolution genetic maps to pinpoint CR resistance genes. These efforts are crucial for improving our understanding of the disease and developing effective management strategies.

Bacillus vallismortis LRB-5: a promising biocontrol agent for mitigating apple replant disease through pathogen suppression and growth promotion - Stress Biology Apple replant disease (ARD) poses a serious threat to apple cultivation, primarily caused by the accumulation of Fusarium species. Bacillus species have demonstrated significant potential as microbial agents, with capabilities in promoting plant growth, suppressing soil-borne pathogens, and improving soil quality. Here in this study, strain LRB-5 was isolated from a healthy apple root system and identified as Bacillus vallismortis based on physiological and biochemical characterization and molecular sequencing analysis. It exhibited broad-spectrum antifungal activity against various Fusarium species, including F. oxysporum, F. moniliforme, F. proliferatum, and F. solani, with inhibition rates exceeding 65%. LRB-5 extracellular metabolites significantly inhibited Fusarium mycelial growth and spore germination. Greenhouse experiments demonstrated that LRB-5 reduced ARD disease severity by more than 50%. The volatile organic compounds produced by LRB-5 exhibited both antimicrobial activity and growth-promoting properties. Further assays revealed LRB-5 can secrete various cell wall-degrading enzymes and possesses plant growth-promoting capabilities. Pot experiments showed LRB-5 had excellent colonization ability in the rhizosphere of Malus hupehensis Rehd. seedlings, significantly increasing seedling biomass, soil bacterial and actinomycete populations, and the activity of root protective enzymes. Moreover, LRB-5 significantly enhanced the activity of soil enzymes while reducing the contents of phlorizin, benzoic acid, and p-hydroxybenzoic acid in the rhizosphere soil. Terminal restriction fragment length polymorphism and quantitative real-time PCR analyses revealed that LRB-5 improved bacterial carbon utilization, increased microbial diversity indices, reduced the abundance of Fusarium spp., and altered the structure of soil microbial communities. Collectively, these rusults suggest that LRB-5 effectively alleviated ARD by protecting apple roots from Fusarium infection and phenolic acid toxicity, optimizing soil microbial communities, and promoting plant growth. Future research should explore the combined application of LRB-5 with other control measures, thereby promoting its practical implementation.

Evolutionary characteristics, expression patterns of wheat receptor-like kinases and functional analysis of TaCrRLK1L16 - Stress Biology Reverse genetics research in complex hexaploid wheat often encounters challenges in determining the priority of gene functional characterization. This study aims to systematically analyze the wheat (Triticum aestivum) receptor-like kinase (TaRLK) gene family and develop an effective strategy to identify key candidate genes for further investigation. We identified 3,424 TaRLKs using bioinformatics methods and analyzed the diverse and conserved evolutionary relationships of RLKs among Arabidopsis, rice and wheat. Based on publicly available and our laboratory’s transcriptome data, we comprehensively analyzed the transcriptional expression patterns of TaRLKs in response to various stresses, particularly Puccinia striiformis f. sp. tritici (Pst). The TaCrRLK1L16, which is upregulated during Pst infection and triggered cell death in Nicotiana benthamiana, has been identified as a key candidate gene for further functional characterization. Furthermore, our results suggested that the transgenic wheat overexpressing TaCrRLK1L16 significantly enhanced resistance to Pst. This study will provide valuable insights into understanding the evolutionary characteristics and expression patterns of TaRLKs while offering a novel strategy for determining the priority of key candidate TaRLKs.
