Peanut is a valuable source of iron for human nutrition. Improving iron content in peanut seeds can enhance both yield potential and nutritional value. In this study, the seed iron content of the 401 peanut germplasm accessions was estimated and substantial variation among these accessions was observed, ranging from 9.02 to 50.60 mg/kg. The seed iron content of <em>valencia</em> type accessions was significantly higher than that of <em>Peruvian</em>, <em>Virginia</em>, and <em>Irregular</em> types. Landraces showed the highest average iron content, followed by advanced cultivars, breeding lines and interspecific hybrid cultivars. Accessions with red seed coat exhibited significantly higher iron content compared with those with pink seed coat. Correlation analysis revealed that the seed iron content significantly negatively correlated with hundred seed weight (HSW), resveratrol and oleic acid. Eight accessions with high iron content were identified with an average iron content of 32.46 mg/kg, including two elite genotypes that Zh.h4280 showed high resveratrol levels (1057.34 μg/kg) and Zh.h1976 exhibited large seeds (HSW over 90g). Association analysis identified four markers, one of which, AHGS2053 stably explained with 5.75%–5.84% phenotypic variation. Accessions containing the favorable allele AHGS2053-250bp exhibited significantly higher iron content compared to those with alternative alleles.

This review synthesizes the integration of genomic selection (GS), genome editing, and epigenetic regulation to operationalize a precision breeding strategy in major oilseed crops. We document how GS, utilizing high-density SNP arrays and sequencing data, has reduced breeding cycles by up to 50% in soybean, enabling rapid selection for complex traits like seed protein content. We highlight the precision of CRISPR-Cas systems in executing design goals, such as creating commercial-grade high-oleic soybeans (>80% oleic acid) by knocking out <em>FAD2</em> genes. Similarly, editing glucosinolate biosynthesis genes in rapeseed has directly improved meal quality. Furthermore, we explore the emerging role of epigenetic regulation as a tunable layer in trait optimization, where DNA methylation patterns in sunflower are linked to drought stress memory and flowering time. Finally, we present an integrated molecular framework, which synergizes these technologies to develop ideotypes with optimized architectures and composition. Despite challenges in phenotyping and global regulation, the strategic implementation of this molecular toolkit is pioneering a new era of precision breeding for the sustainable intensification of oilseed production.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"11 1","pages":"Pages 28-37"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147539237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the nodulation efficiency of <em>Bradyrhizobium</em> and <em>Sinorhizobium</em> strains under different soil conditions and evaluated their impacts on the rhizocompartment bacterial community. We found that inoculation with <em>Bradyrhizobium diazoefficiens</em> UASD 110 increased the number of soybean nodules in acidic soil, while <em>Sinorhizobium fredii</em> CCBAU 45436 was more effective in alkaline soil. However, inoculation with neither strain significantly affected nodulation in neutral soil. Then, we demonstrated that UASD 110 was more competitive in nodulation than CCBAU 45436, which was related to its higher abundance in the rhizosphere. Furthermore, we showed that while single inoculation with UASD 110 or CCBAU 45436 failed to alter the bacterial diversity, these two strains differentially influenced the rhizosphere microbial composition. Finally, we identified the main rhizosphere microorganisms that were affected by these two strains. Our findings revealed that the nodulation capacity of rhizobia and their colonization of rhizosphere and nodules are soil-type dependent, yet their impact on the rhizobacterial community exhibited consistent patterns.

However, the efficacy or mechanism of flaxseed plant milk (FPM), a functional beverage derived from flaxseed, in alleviating constipation has not yet been clearly established. In this study, network pharmacology was combined with <em>in viv</em>o experiments to evaluate the anti-constipation activity of FPM on water restriction-induced constipation mouse model. Compared with the model group, administration of FPM (100 mg/kg and 200 mg/kg) significantly shortened the time to first black stool excretion, increased number of fecal pellets and water content of fecal pellets, and improved Small Intestinal Transit Rate (<em>p <</em> 0.05). Histological analysis revealed that FPM (200 mg/kg) preserved colonic epithelial integrity, reduced lamina propria damage, and restored goblet cell populations. Serum biochemical assays showed that FPM decreased vasoactive intestinal peptide (VIP) levels and increased 5-hydroxytryptamine (5-HT) concentrations. Network pharmacology identified 214 overlapping targets between flaxseed bioactive compounds and constipation-related genes, with key hub targets including TP53, CASP3, TNF, and IL6. KEGG pathway enrichment suggested that the PI3K/AKT signaling pathway may serve as a central regulatory axis. Western blot further confirmed that p-PI3K and p-AKT protein levels in the colon were reduced in constipated mice, whereas FPM administration markedly restored their expression, indicating activation of the PI3K/AKT pathway. Overall, these findings demonstrate that FPM alleviates constipation by improving stool characteristics, enhancing intestinal motility, and maintaining mucosal integrity, potentially via modulation of the PI3K/AKT pathway.
