To address these challenges, we performed a systematic, genome‐wide mapping in a biparental population and a population of diverse hybrids. Leveraging both a triple testcross and immortalized F <jats:sub>2</jats:sub> designs, we examined the genetic basis of the heterosis of the wheat hybrid <jats:italic>Piko</jats:italic> × <jats:italic>Hermann</jats:italic> . We detected a major hQTL on chromosome 4B, primarily driven by epistasis. This region contains the <jats:italic>Green Revolution</jats:italic> gene <jats:italic>Rht‐B1</jats:italic> as the primary candidate gene. Then, we used a population of ~6000 wheat hybrids, derived from crosses between diverse Central European inbred lines, to perform a one‐dimensional scan for hQTL. This scan identified 174 hQTL for grain yield, 70 for heading date, and 166 for plant height. Further dissection of these hQTL revealed that epistatic interactions predominantly contribute to heterosis. We discovered an epistatic hub at the distal end of chromosome 4A coinciding with an alien introgression region from emmer wheat. A data‐driven, integrative analysis combining high‐resolution SNP data, sequence variant annotation, and hQTL signals from the population uncovered <jats:italic>TraesCS7B03G1341000</jats:italic> as the candidate gene underlying grain yield heterosis. Our findings deepen the understanding of the genetic architecture of heterosis in wheat by shifting from hQTL to candidate genes and provide insights into their application in hybrid wheat breeding.","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"136 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148858880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SPc assembles with dsRNA via electrostatic interactions, hydrogen bonding and Van der Waals forces, forming stable nanoscale complexes.

However, ATAC-seq does not precisely indicate active transcriptional activity. In contrast, Ketoxal-Assisted Single-stranded DNA sequencing (KAS-seq) has been widely deployed in capturing genome-wide single-stranded DNA (ssDNA) using N&lt;sub&gt;3&lt;/sub&gt;-kethoxal–assisted labelling in situ (Lyu et al. &lt;span&gt;2022&lt;/span&gt;), which facilitates fast and accurate analysis of transcription dynamics in mammals (Wu et al. &lt;span&gt;2020&lt;/span&gt;). Active chromatin state beyond promoters has been widely applied to predict enhancers in plants, while an active chromatin environment does not necessarily mean an active enhancer (Tippens et al. &lt;span&gt;2020&lt;/span&gt;). Since, Pol II is known to bind at certain enhancers (Kim et al. &lt;span&gt;2010&lt;/span&gt;), while KAS-seq maps a portion of possible enhancers containing Pol II–mediated transcription bubbles in ssDNA structures and provide a precise foot printing of transcriptional activity (Wu et al. &lt;span&gt;2020&lt;/span&gt;). Pol II–engaged enhancers, therefore, can be readily mapped through measuring KAS-seq as well. ATAC-seq serves to identify open chromatin regions that are devoid of nucleosomes, thereby rendering both promoter and enhancer regions accessible for TF binding. However, ATAC-seq signals do not reflect the activity of Pol II elongation, thus failing to identify the active enhancers and their activity. Therefore, the integration of ATAC-seq and KAS-seq probably provides a more accurate prediction of active single-stranded enhancers.&lt;/p&gt;&lt;p&gt;We therefore deployed the rice seedling photomorphogenesis system (Li et al. &lt;span&gt;2025&lt;/span&gt;) to explore application of KAS-seq techniques in rice. At first, we optimised the KAS-seq method using as little as 200 ng gDNA (low input) within rice nuclei (Figure 1a). The dot blot assay showed high compatibility of N&lt;sub&gt;3&lt;/sub&gt;-kethoxal–assisted labelling in rice nuclei (Figure 1b). The remaining labelled nuclei were collected for the KAS-seq experiment. We then assigned KAS-seq peaks to gene structure and found the peak distribution was quite different from that of ATAC-seq. Specifically, KAS-seq peaks in the promoter region dramatically reduced to 25% compared with ATAC-seq peaks, which was accompanied by a sharp increase of the peaks assigned to gene body regions (Figure 1c) consistent with the result observed in KAS-seq data derived from human cell (Wu et al. &lt;span&gt;2020&lt;/span&gt;). The metagene profile of KAS-seq reads showed a pronounced and sharp peak near the transcription start site (TSS) similar to that of ATAC-seq signals, while a strong, broad peak surrounding the transcription end site (TES) was observed in the KAS-seq reads opposite to the lowest peak intensity at TES in the ATAC-seq reads (Figure 1d).
