Summary The wheat Lr34res allele, coding for an ATP ‐binding cassette transporter, confers durable resistance against multiple fungal pathogens. Lr34sus differing from by two critical nucleotide polymorphisms, is found in susceptible cultivars. functionally transferrable as a transgene into all major cereals, including rice, barley, maize, and sorghum. Here, we used transcriptomics, physiology, genetics, vitro vivo transport assays to study the molecular function of Lr34 . We report that...
Summary The wheat gene Lr34 confers durable and partial field resistance against the obligate biotrophic, pathogenic rust fungi powdery mildew in adult plants. resistant allele evolved after domestication through two gain‐of‐function mutations an ATP ‐binding cassette transporter gene. An ‐like fungal disease with a similar broad‐spectrum specificity durability has not been described other cereals. Here, we transformed into japonica rice cultivar Nipponbare. Transgenic plants expressing...
Summary Maize (corn) is one of the most widely grown cereal crops globally. Fungal diseases maize cause significant economic damage by reducing yields and increasing input costs for disease management. The sustainable control through release planting cultivars with durable resistance. wheat gene Lr34 provides partial field resistance against multiple fungal wheat, including three rust pathogens powdery mildew. Because its unique qualities, became a cornerstone in many programmes. encoded...
Summary The wheat gene Lr34 encodes an ABCG‐type transporter which provides durable resistance against multiple pathogens. is functional as a transgene in barley, but its mode of action has remained largely unknown both and barley. Here we studied expression uninfected barley lines transgenic for . Genes from defense pathways contributing to basal inducible disease were constitutively active seedlings mature leaves. In addition, the hormones jasmonic acid salicylic induced high levels,...
Plant diseases are a serious threat to crop production. The informed use of naturally occurring disease resistance in plant breeding can greatly contribute sustainably reduce yield losses caused by pathogens. Ta-Lr34res gene encodes an ABC transporter protein and confers partial, durable, broad spectrum against several fungal pathogens wheat. Transgenic barley lines expressing showed enhanced powdery mildew leaf rust barley. While is only active at adult stage wheat, was found be highly...
Plant pathogens with a broad host range are able to infect plant lineages that diverged over 100 million years ago. They exert similar and recurring constraints on the evolution of unrelated populations. Plants generally respond quantitative disease resistance (QDR), form immunity relying complex genetic determinants. In most cases, molecular determinants QDR how they evolve is unknown. Here we identify in Arabidopsis thaliana gene mediating against Sclerotinia sclerotiorum, agent white mold...
Abstract Quantitative disease resistance (QDR) is a conserved form of plant immunity that limits infections caused by broad range pathogens. QDR has complex genetic determinism. The extent to which molecular components the response vary across species remains elusive. fungal pathogen Sclerotinia sclerotiorum, causal agent white mold diseases on hundreds species, triggers in host populations. To document diversity local responses S. sclerotiorum at level, we analyzed complete transcriptomes...
Abstract Despite large omics datasets, the establishment of a reliable gene annotation is still challenging for eukaryotic genomes. Here, we used reference genome major fungal wheat pathogen Zymoseptoria tritici (isolate IPO323) as case study to develop methods improve prediction. Four previous IPO323 annotations identified 10,933 13,260 models, but only one third these coding sequences (CDS) have identical structures. To resolve discrepancies and generated full-length transcripts using...
The 'breaker' element ( GcB ) of the gametocidal locus derived from Aegilops sharonensis has been mapped to a region proximal block sub-telomeric heterochromatin on chromosome 4S (sh) L. production alien addition lines allows transfer useful genetic variation into elite wheat varieties related wild species. However, some relatives wheat, particularly those within Sitopsis section genus Aegilops, possess chromosomes that are transmitted preferentially offspring when generated. Species group S...
Durable resistance against fungal pathogens is highly valuable for disease management in agriculture. For its sustainable use, and to avoid pathogen adaptation, it important understand the underlying molecular mechanisms. Many studies on durable plants have focused exclusively host plant, whereas possible reactions adaptations of exposed this type not been well researched. The wheat Lr34 gene, encoding a putative ABC ‐transporter, provides broad‐spectrum multiple functional as transgene all...
ABSTRACT Acclimation enables plants to adapt immediate environmental fluctuations, supporting biodiversity and ecosystem services. However, global changes are altering conditions for plant disease outbreaks, increasing the risk of infections by pathogenic fungi oomycetes, often undermining immune responses. Understanding molecular basis acclimation is crucial predicting climate change impacts on ecosystems improving crop resilience. Here, we investigated how Arabidopsis thaliana quantitative...
