Soybean cyst nematode (SCN) disease caused by Heterodera glycines is one of the most devastating diseases in soybean ( Glycine max L.) and results significant yield losses annually worldwide. Breeding crops for resistance an eco-friendly approach to minimize these losses. In this study, SCN-resistant germplasm with excellent agronomic traits was obtained through cross-breeding between resistant sources local cultivars that were high-yielding but susceptible SCN China’s two major soybean-growing regions. Using single seed descent method, plants favorable selected then planted into rows raise seeds marker assays environmental-controlled bioassays. Finally, three lines from Northeast China Huang-Huai Valleys, all harboring races 1, 3, 5, selected. Their 100-seed weight ranged 18.91 g 21.6 g. The average oil contents high-oil-content (QingF6-67, QingF6-98, QingF6-99) 19.96% 22.74%. protein (HHF7-3-10, HHF7-6-6, HHF7-6-10) Valleys 42.3% 43.5%. These six lines, which have increased or contents, could be used as against advanced donor parents breeding programs.

Soybean cyst nematode (SCN, Heterodera glycine Ichinohe) is a major threat to global soybean yield. Resistance genes at the rhg1 locus from PI 88788 are majorly utilized in 95% of U.S. breeding programs. Continuous use this resistance source leads shift virulence SCN populations and overcomes host resistance. Therefore, it necessary identify alternative sources combat ever-changing pest. Previously, we identified an exotic line, 567516C, which carries novel qSCN10 (O) for demonstrating different responses compared known Rhg4 loci. Here, narrowed QTL region 142-kb (containing 20 genes). Based on gene expression, ontology, in-silico analysis, QTL-based haplotyping, two were functional characterization. Overexpression transcription factor TGA1-related Shugoshin C-terminus SCN-susceptible Williams 82 reduced number by 6.4-fold (84.6%) 5.3-fold (81.2%), respectively. GmTGA1-10 GmSCT-10 Tilling mutants showed high numbers. The associated with have significant potential reduce population. They also offer durable that independent Rhg4. A characterization study reveals presence tightly linked conferring broad-spectrum (SCN). These hold countering shifts virulence.

Japanese soybeans are traditionally bred to produce soy foods such as tofu, miso and boiled soybeans. Here, investigate their distinctive genomic features, including structural variations (SVs), we constructed 11 nanopore-based genome references for other soybean lines. Our assembly-based comparative method, designated 'Asm2sv', identified gene-level SVs comprehensively, enabling pangenome analysis of 462 worldwide cultivars varieties. Based on these, selective sweeps between US soybeans, one which was the pod-shattering resistance gene PDH1. Genome-wide association studies further several quantitative trait loci that accounted large-seed phenotypes lines, some were also close regions sweeps, Notably, specific combinations alleles, SVs, found increase seed size landraces. In addition differences in cultivation environments, distinct food processing usages might result changes genomes. Long-read assemblies seven Japanese, three North American primitive Glycine max highlight variation underlying morphology phenotypes.

Sorghum (Sorghum bicolor L.) is a globally important energy and food crop that becoming increasingly integral to security the environment. However, its production significantly hampered by various fungal phytopathogens affect yield quality. This review aimed provide comprehensive overview of major affecting sorghum, their impact, current management strategies, potential future directions. The diseases covered include anthracnose, grain mold complex, charcoal rot, downy mildew, rust, with an emphasis on pathogenesis, symptomatology, overall economic, social, environmental impacts. From initial use fungicides shift biocontrol, rotation, intercropping, modern tactics breeding resistant cultivars against mentioned are discussed. In addition, this explores disease management, particular focus role technology, including digital agriculture, predictive modeling, remote sensing, IoT devices, in early warning, detection, management. It also key policy recommendations support farmers advance research thus emphasizing need for increased investment research, strengthening extension services, facilitating access necessary inputs, implementing effective regulatory policies. concluded although pose significant challenges, combined effort innovative policies can mitigate these issues, enhance resilience sorghum facilitate global issues.
