Biotic stresses include the infestation of crops by an array pathogenic microbes like bacteria, viruses, fungi, nematodes, and insect pests. Pathogenic have always threatened crop plants their produce. With growing global population changing environmental conditions, there is a need for that can tolerate stress. Over years, significant progress has been made in elucidating functional role major transcription factors (TFs) families plant disease resistance. Among TFs, APETALA2/ethylene response factor (AP2/ERF) family members emerged as pivotal regulators growth, development, responses to stresses. AP2/ERF are key resistance, integrating pathogen signals mediate salicylic acid (SA), jasmonic (JA), ethylene (ET) pathways, activate defense genes, enhance reactive oxygen species (ROS) production, modulate cell wall defenses effective immune responses. They influence modulating hypersensitive reactions serving virulence targets effectors. By enhancing responses, TFs contribute developing genetically improved with increased resistance biotrophic necrotrophic pathogens, thereby reducing losses improving yield stability under pressure. This review offers comprehensive overview current understanding microbial pathogens acting downstream mitogen-activated protein kinase (MAPK) cascades.

ABSTRACT Blast caused by Pyricularia oryzae (synonym Magnaporthe ) is a major fungal disease affecting productivity and quality in rice‐growing areas globally. A genome‐wide association study (GWAS) was performed using the blast score(s) whole‐genome sequence data pertaining to subset of 280 diverse accessions IRRI 3 K Rice Genome panel. Continuous variation observed, with 8.9% total resistant, 39.6% moderately 37.2% susceptible 14.2% susceptible, average severity ratings 0 3, > 5, 5 7 9, respectively, indicating polygenic inheritance trait. We identified potential different subpopulations resistance reaction (IRGC 127151 [subtrop], 127738 [ind2], 132245 [aro] 127130 [aus]), having lowest < 2. GWAS revealed significant 22 quantitative trait nucleotides (QTNs)—20 main effect two interaction effect—linked that led identification 43 plant defence‐related candidate genes. The haplo‐pheno analysis genes (LOC_Os02g06470, LOC_Os02g06510, LOC_Os07g34370, LOC_Os08g29760, LOC_Os10g07470 LOC_Os12g34290) associated superior haplotypes were play critical role defence mechanisms. resistant sources hold promise for stacking into an elite genetic background haplotype‐based breeding approach development cultivars wide range pathotypes.

Ethylene response factors (ERFs) are transcription that essential in modulating drought stress responses plants such as Arabidopsis and rice. However, the functional role of ERF wheat remains unclear. We identified 33 genes under using transcriptomic analysis categorized them into eight subfamilies (I–VIII). Among them, 12 drought-responsive candidate were upregulated, TaERF13-2B was selected for further analysis. overexpression resulted significantly reduced survival rates conditions with decreased expression stress-responsive antioxidant enzyme genes, indicating gene elevated sensitivity transgenic . In wheat, increased malondialdehyde accumulation, chlorophyll proline levels, activity. Furthermore, antioxidant-related suppressed, suggesting negatively regulates to stress. The interactions between TaCIPK9 confirmed yeast two-hybrid bimolecular fluorescence complementation. Overall, these discoveries deepen our insights family contribute elucidation wheat.

Abstract Fire blight of pear is caused by Erwinia amylovora, which can cause devastating damage to trees and other pome fruit worldwide. has resulted in a reduction the production Korla fragrant pears Xinjiang, China, as well decrease their quality taste, causing severe economic losses. To this end, comparative transcriptome analysis common (KFP, susceptible) bud mutation line (1910, resistant) at three inoculation periods was conducted. Clustering principal component (PCA) RNA-seq data revealed that differences between lines were greater than those within lines. A total 7271 DEGs identified line, while 11,937 KFP. Between KFP resistant material identified, significantly enriched pathways photosynthesis, jasmonic acid metabolic process, flavonoid biosynthesis, starch sucrose metabolism. 8 clusters for all (17,354) via k-means, KEGG pathway annotations performed each individual cluster. In addition, 1027 differentially expressed transcription factors (TFs) clustered into five clusters, TFs with largest fold change cluster identified. gene coexpression network further constructed through weighted correlation (WGCNA), 15 key genes determine fire resistance These research results provide theoretical basis deeper understanding molecular mechanism new genetic resources study blight.

Abstract Plant cells undergo extensive transcriptional reprogramming following pathogen infection, with these patterns becoming more complex when pathogens, such as hemibiotrophs, exhibit different lifestyles. These changes are often orchestrated by MYB, WRKY and AP2/ERF transcription factors (TFs), which modulate both growth defence‐related gene expression. Transcriptional analysis of genes in avocado ( Persea americana ) infected Phytophthora cinnamomi indicated differential immune response activation comparing a partially resistant susceptible rootstock. This study identified 226 MYB , 82 174 TF‐encoding avocado, using genome‐wide approach. Phylogenetic revealed substantial sequence conservation within TF groups underscoring their functional significance. RNA‐sequencing rootstock P. was indicative an switch occurring either after 24 6 h post‐inoculation, respectively. Different clusters co‐expressed were observed at times, suggesting the necrotroph‐related responses varying intervals between two rootstocks. aids our understanding role TFs therein, elucidating disparities

Abstract Host-virus interactions determine infection outcomes, with cellular heterogeneity playing a critical role in the dynamic interplay between host immune responses and viral evasion strategies. While animal plant viruses use different mechanisms for cell entry, tropism is essential pathogenesis across both kingdoms. To examine this overarching hypothesis, we studied sweet potato virus disease, most devastating disease affecting (Ipomoea batatas), which involves synergistic co-infection by aphid-transmitted feathery mottle whitefly-transmitted leaf curl virus. By integrating single-cell RNA-Seq profiling phenotypic assessments, mapped specificity to particular type within plant. As result, we: 1) generated comprehensive atlas of leaves, documenting transcriptional response 38,526 cells during co-infection; 2) traced virus-infected examining genomic reads each cell; 3) identified tissue mesophyll, suggesting that selectively targeting highly active machinery common theme viruses; finally 4) characterized VIPE1, an AP2/ERF family transcription factor contributes resistance potato. These findings highlight differential susceptibility at levels, underscoring importance understanding specific molecular features developing targeted strategies managing viruses.
