Published: March 6, 2025

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.

Integrated Metabolomic and Transcriptomic Analysis Reveals the Pharmacological Effects and Differential Mechanisms of Isoflavone Biosynthesis in Four Species of Glycyrrhiza

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(6), P. 2539 - 2539

Published: March 12, 2025

Licorice (Glycyrrhiza L.) is a globally popular medicinal and edible plant, with nearly 30 species distributed across all continents. The usable part primarily the root. To understand metabolic differences among different Glycyrrhiza species, we selected four performed comprehensive analyses of their roots. Metabolomic profiling was conducted using UPLC-MS/MS GC-MS, while transcriptomic analysis carried out RNA-sequencing. A total 2716 metabolites were identified, including flavonoids (527 types) terpenoids (251 types), various other components. Subsequently, network pharmacology employed to explore value potential pharmacological ingredients these metabolites. Joint metabolomic data revealed significant in differentially accumulated (DAMs) expressed genes (DEGs) pairwise comparisons species. These enriched isoflavone pathway. Further investigation into regulatory mechanisms biosynthesis identified key involved biosynthesis. Finally, made reasonable predictions suitable habitats for aiming provide new insights development utilization licorice resources. results this study can serve as basis in-depth research on regulation licorice.

Mapping of Phytophthora sojae resistance in soybean genotypes PI 399079 and PI 408132

Crop Science, Journal Year: 2025, Volume and Issue: 65(2)

Published: March 1, 2025

Abstract Numerous novel sources of resistance to Phytophthora sojae , which causes root and stem rot soybean ( Glycine max [L.] Merr), have been identified, but not all loci mapped few cloned. Two plant introductions (PIs), PI 399079 408132, were identified as Rps ‐gene mediated through inoculations with numerous isolates individually a combination three P. . Resistance was in F 7 9 recombinant inbred line (RIL) populations derived from crosses the susceptible cultivar Williams two PIs. controlled by genes depending on isolate(s). Thus, quantitative trait locus mapping used four disease (QDRL) 408132 RIL populations, respectively. Each conferred different isolates. QDRL chromosome 7, one is second may be an allele Rps11 previously 594527. These results indicate that there are new alleles known these

Registration of ‘R19C‐1012’: A high‐yielding soybean cultivar with improved flooding tolerance at early vegetative stages

Journal of Plant Registrations, Journal Year: 2025, Volume and Issue: 19(2)

Published: April 27, 2025

Abstract ‘R19C‐1012’ (Reg. no. CV‐564, PI 707837) is a high‐yielding, conventional maturity group Mid‐IV (Relative 4.6) soybean [ Glycine max (L.) Merr.] cultivar with improved flooding tolerance at V2–V4 vegetative growth stages. It was developed and released by the University of Arkansas System–Division Agriculture Research & Extension Center in 2024. R19C‐1012 has an indeterminate habit, purple flowers, gray pubescence, brown pods, seed imperfect black hilum. From 2019 to 2023, evaluated across 40 irrigated environments, average grain yield 4302 kg ha −1 , representing 93% 99% relative Xtend non‐Xtend checks, respectively. Under conditions stages, outperformed checks advantage +158%.
