Recently developed machine learning methods, such as deep learning and gradient boosting, are transforming the real world. These methods could advance QTL mapping methodologies because of their high capability for capturing complex relationships among features. One problem with applying such complex models to QTL mapping is the evaluation of feature importance. In this study, XGBoost, a popular gradient tree boosting algorithm, was applied for QTL mapping in biparental populations with Shapley additive explanations (SHAPs). SHAP is a local (i.e., instance-wise) importance index with the desired properties as feature importance indices. The SHAP-assisted XGBoost (SHAP-XGB) was compared with conventional methods, including composite interval mapping (CIM), multiple interval mapping (MIM), inclusive CIM (ICIM), and BayesC, using simulations and rice heading date data. SHAP-XGB performed comparably to CIM, MIM, ICIM, and BayesC in mapping main QTL effects and was superior to MIM, ICIM, and BayesC in mapping QTL interaction effects. As SHAP can evaluate local importance, interactions between markers can be visualized by plotting SHAP interaction values for each instance (plant/line). These results illustrated the strength of SHAP-XGB in detecting and interpreting epistatic QTLs and suggest the possibility that SHAP-XGB complements conventional methods.","PeriodicalId":9258,"journal":{"name":"Breeding Science","volume":"75 5","pages":"378-391"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13129572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147811469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined analysis with transcriptome data revealed that the hyperspectral profile had potential to predict the degree of expression of developmentally regulated genes. In addition, principal component analysis of hyperspectral imaging data made it possible to detect growth-stage dependent dynamics and to distinguish differences between subspecies as well as field conditions by selecting an adequate pretreatment method. Furthermore, we obtained hyperspectral data for brown rice grains of recombinant inbred lines derived from a cultivar with high temperature tolerance during the ripening stage and with a good grain appearance. We then performed quantitative trait locus analysis using the extracted principal component scores and trait values related to grain appearance to explore the possibility of using spectral analysis for genetic studies.","PeriodicalId":9258,"journal":{"name":"Breeding Science","volume":"75 5","pages":"349-357"},"PeriodicalIF":2.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13129574/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147811511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given their larger scale compared to single nucleotide polymorphisms and small insertions and deletions, SVs are expected to be associated with various traits in several crops and fruit species. They can also be used to identify plant cultivars. However, it is challenging to detect SVs using short-read next-generation sequencing (NGS), which, until recently, has been the mainstream method, due to its short read length compared to SVs. In recent years, long-read NGS, which generates reads exceeding the length of SVs, has made SV detection more feasible. To take advantage of this, we developed LAYLA (Large indel AnalYzer for muLti-sAmple), a pipeline program designed to comprehensively detect and visualize SVs across multiple samples using long-read data. Here, we applied LAYLA to 13 citrus founder cultivars used in Japanese breeding and Citrus unshiu Marc. We identified SVs at 59,983 positions in the reference genome. This analysis revealed both common and cultivar-specific SVs. Furthermore, we designed primers targeting nine selected SVs and conducted experimental validation, confirming the presence of SVs detected by LAYLA.

We found no correlations between LBS and the other three. These were classified into three clusters: A, B1 and B2, based on these trait variations. Cluster A consists mainly of lowland Japonica and Indica Groups, exhibiting the lowest LBS and RDW that were intermediate between B1 and B2. Clusters B1 and B2 included both Japonica and Indica Groups' varieties, as well as the 18 upland NERICAs. B1 displayed the highest RDW and a LBS that was intermediate between A and B2. Conversely, B2 had the highest LBS and the lowest RDW. Both the Indica and Japonica Groups displayed extensive variation in tolerance to iron toxicity. Moreover, LBS and RDW are controlled by different genetic mechanisms. In our association analysis using NERICAs, we identified two quantitative trait loci (QTLs): one for LBS on chromosome 9, which is a novel discovery, and another for Control-DW, which enhances tolerance through O. glaberrima alleles.","PeriodicalId":9258,"journal":{"name":"Breeding Science","volume":"75 4","pages":"292-302"},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051631/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this initial study, we assessed the feasibility of GP in 156 F1 accessions derived from 20 parents within 132 inbred C. annuum accessions. Capsaicinoid content (capsaicin, dihydrocapsaicin, and their total) was quantified using high-performance liquid chromatography. Inheritance analysis revealed that nearly half of the F1 accessions exhibited high-parent heterosis (F1 > higher parent), particularly in crosses between lower-pungency parents. We then performed GP for F1 accessions using 3,149 single nucleotide polymorphisms from inbred accessions. Among 11 models tested, GBLUP-GAUSS tended to show high accuracy, with predicted values showing a significant positive correlation (r = 0.770, P < 0.01) with observed capsaicinoid content (μg·gDW-1), although the involvement of heterosis in reducing accuracy was observed.

Through the phenotypic screening of the population based on the seed cesium concentration, 10 candidate low-cesium-accumulating mutant lines were selected. Five of these exhibited significantly reduced seed radiocesium concentrations compared with the original variety, and one had accumulated an excessive amount of sodium. Since plant intracellular sodium ion homeostasis is regulated by the salt overly sensitive (SOS) pathway, sequence analysis of GmSOS1, which encodes an Na+/H+ antiporter in this pathway, revealed that the high-sodium-accumulating line contains a mutation in this gene. Additionally, two more gmsos1 mutant lines were isolated from the mutant population. In the field trial, the three independent gmsos1 mutant lines possessed lower seed cesium concentrations than the wild type.

Many genes involved in salt stress have been identified, but this knowledge has not led to development of a salt-tolerant crop that are practically useful. Despite hundreds of transgenic plants have been tested, there are few examples that demonstrated yield performance that are practically applicable to salt-affected fields. It is therefore important to figure out which genes should be targeted for artificial manipulation. However, given there are >500 of genes involved, it is almost impossible to test all the possible combinations of genes and expression profiles even in model plants. In contrast, wild plants inhabiting coastal environments have acquired salt tolerance, often by enhancing the mechanisms that are also conserved in model plants. Elucidating the mechanisms and underlying genes in such wild plants should provide a clear guidance to the combinations of appropriate genes. The genus Vigna represents such wild plants because of its great diversity. Recent studies have revealed that multiple Vigna species have independently evolved salt tolerance in various ways. Some of the species are studied in detail, highlighting the significance of combining and pyramiding multiple mechanisms for improving salt tolerance of a plant.","PeriodicalId":9258,"journal":{"name":"Breeding Science","volume":"75 4","pages":"245-254"},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051636/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
