Rust diseases, caused by fungal pathogens pose a substantial threat to global wheat production including India. The 2NvS translocation carrying Lr37-Sr38-Yr17 from Aegilops ventricosa has been pivotal in developing disease-resistant wheat, hosting essential resistance genes against various diseases. Recent research suggests its potential effectiveness the globally emerging of blast. Initially, conventional backcross breeding efforts were attempted integrate this gene cluster into ten adapted Indian bread cultivars. Extensive phenotyping populations at seedling and adult stages led creation rust-resistant BC7F8 near isogenic lines (NILs) with desirable traits. However, approach proved time-consuming relied on disease pressure, ultimately resulting these no longer being cultivation. Subsequently, marker-assisted employing VENTRIUP/LN2 molecular marker was employed confirm presence facilitate transfer modern varieties, notably HD 2733, PBW 343, DBW39, 2967 HW 2045 particularly targeting North Eastern Plain Zone combat blast using previously developed as donor BC3F6 generation. integration via method limited represents significant stride rust breeding, offering promising bolster food security fostering development varieties.

Besides directly affecting yield, mycotoxin residing in kernel greatly threatens health humans and livestock. Xinong 979 (XN979) a widely cultivated elite with high yield FHB resistance. However, its resistance mechanism remains unclear. In this study, we studied expression genes involved plant defense XN979 comparative transcriptomics. We found that consists two lines defense. The first line defense, which constitutive, knitted via enhanced basal lignin jasmonic acid (JA) biosynthesis genes. second induced upon F. graminearum infection, contributed limited suppression photosynthesis struggle biotic stress-responding Meanwhile, effective leads to an inhibition gene expression, especially early infection stage. formation may coincide breeding strategies, such as selecting grain lodging traits.

This paper discusses the mechanisms by which fungi manipulate plant physiology and suppress defense responses producing effectors that can target various host proteins. Effector-triggered immunity effector-triggered susceptibility are pivotal elements in complex molecular dialogue underlying plant-pathogen interactions. Pathogen-produced effector molecules possess ability to mimic pathogen-associated patterns or hinder binding of pattern recognition receptors. Effectors directly nucleotide-binding domain, leucine-rich repeat receptors, downstream signaling components defense. Interactions between these receptor-like kinases plants critical this process. Biotrophic adeptly exploit networks key hormones, including salicylic acid, jasmonic abscisic ethylene, establish a compatible interaction with their hosts. Overall, highlights importance understanding interplay fungal develop effective strategies for disease management.

Abstract Nucleotide-binding site leucine-rich repeat (NLR) disease-resistance genes typically confer resistance against races of a single pathogen. We report that Lr/Yr548, an NLR gene from Aegilops sharonensis and longissima, confers specific Puccinia triticina (Pt) P. striiformis tritici (Pst) cause leaf stripe rust, respectively. Lr/Yr548 prevented disease development in wheat introgression as well transgenic lines.

Wheat leaf rust ( Puccinia triticina ) is one of the most significant fungal diseases wheat, causing substantial yield losses worldwide. Infestation currently being reduced by fungicide treatments and mostly vertical resistance. However, these measures often break down when virulence pattern changes, resulting in a breakdown resistances. In contrast, prehaustorial resistance (phr) that occurs einkorn–wheat interaction race-independent, characterized an early defense response plants during phase infestation. Einkorn Triticum monococcum closely related to urartu as progenitor wheat generally shows high level against wheat. Hence, einkorn can serve valuable source improve pathogen future lines. particular, accession PI272560 known exhibit hypersensitive effector triggered immune reaction, preventing infection P. .

Yr30, an adult plant (APR) gene with broad-spectrum effectiveness, was located in putatively pleiotropic locus or QTL harbors genes Sr2, Lr27, Pm70, Sb3 and Pbc1. Although has been widely deployed worldwide achieve durable for over centenary little known about genetic relationship causal because effects are small inconstant different backgrounds environments. In this study, we identified residual heterozygous line (RHL), YM91, derived from Yaco"S"/Mingxian169 F5:6 RIL population, where Yr30 present alone, as dominant clearly distinguishable. Through selection plants large mapping population developed. Yr30 was fine-mapped 0.52-cM interval between KASP markers AX-109525141 YM3B-7 corresponding physical distance 610 kb on chromosome 3BS.
