The mutant <i>je0166</i> was sensitive to exogenous gibberellin, but its sensitivity was lower than that of its wild type. Genetic analysis on plant height and gene mapping located the target region to a 4.07 cM interval on chr. 4AL.

We also found large fragment inversions in the genetic map of the mutant. The novel allele diversifies natural allelic variations and could be utilized in future wheat improvement.

In arid regions, varieties possessing longer coleoptile can evade harsh conditions by deep sowing, paving the way for improved yield. However, the study of genes involved in coleoptile development is insufficient. In this study, a high-density 660 K SNP array was used for genome-wide association study (GWAS) on coleoptile length in 150 wheat varieties. The findings revealed the detection of 353 significantly associated SNPs across all environments. The integration of linkage disequilibrium analysis and haplotype analysis mined 23 core QTLs capable responsible for the stable regulating coleoptile length in wheat. In wheat varieties characterized by extended coleoptile length, 6,600, 11,524, and 6,059 genes were found to be differentially expressed at three distinct developmental stages within the coleoptile, respectively. Through GWAS, gene expression levels, and functional annotation, we concluded the identification of two candidate genes (<i>TraesCS2B02G423500</i>, <i>TraesCS2B02G449200</i>) regulating wheat coleoptile length. By employing WGCNA and protein interactions prediction, discovered that the 19 genes were found to interact with candidate genes and participate in plant hormone metabolism and signaling, cell elongation or proliferation, which collectively contributing to coleoptile elongation. Additionally, two KASP markers were developed which can be used in breeding. These results offer a basis for understanding the genetic regulatory network responsible for wheat coleoptile length formation. The QTLs and candidate genes identified in this study can be further utilized for genetic improvement of wheat coleoptile length.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s11032-024-01520-6.</p>","PeriodicalId":18769,"journal":{"name":"Molecular Breeding","volume":"44 11","pages":"78"},"PeriodicalIF":2.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11561208/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142648274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distant hybridization is a powerful method for plant breeding and genetic improvement, whereas the genetic basis in interspecific F<sub>1</sub> progeny of chrysanthemums needs to be better understood for breeding purposes. In this study, the leaf and floral traits of the 273 reciprocal interspecific F<sub>1</sub> hybrids of diploid <i>C. dichrum</i> (YSJ) and <i>C. nankingense</i> (JHN) were analyzed along with their SNP-derived genetic structure to elucidate the influence of differences in genetic background between the parents on the hybrid performance. We then performed a genome-wide association analysis (GWAS) to reveal the investigated traits' genomic loci and candidate genes. Considerable phenotypic variation (8.81% ~ 55.78%) and heterosis with transgressive segregation in both directions were observed in the reciprocal progenies. We observed a higher level of phenotypic variation in JHN × YSJ rather than in YSJ × JHN. Also, a significant reciprocal effect was observed for most examined traits. Based on the SNP data, we separated the hybrid progenies into three groups (I, II, and III), albeit imperfectly dependent on the cross directions, except for some reciprocal hybrids clustering into group II. Group I from YSJ × JHN and Group III from YSJ × JHN differed with contrasting <i>F</i> <sub><i>ST</i></sub> and π ratios, indicating the genetic changes in the reciprocal populations. The outcome of GWAS via the IIIVmrMLM method detected 339 significant quantitative trait nucleotides (QTNs) and 40 suggestive QTNs, and the phenotypic variation explained by a single QTN ranged from 0.26% to 7.42%. Within 100 kb upstream and downstream of the important QTNs, we discovered 49 known genes and 39 new candidate genes for the investigated leaf and floral traits.

Yet, owing to its multifaceted nature, crispness remains a formidable challenge in artificial enhancement efforts. To expedite the early and precise evaluation of apple crispness, this study centered on a hybrid population derived from 'Fuji' and 'Pink Lady' cultivars, showcasing segregating crispness traits. We conducted measurements of flesh water content, cellular anatomical morphology, and employed a texture analyzer to assess mechanical properties of the offspring flesh. Integrating these three dimensions, we conducted a comprehensive analysis of quantitative characteristics of apple crispness, juxtaposed with sensory evaluation. Utilizing BSA-seq technology, we scrutinized extreme phenotypic individuals, revealing QTL loci intricately linked to the aforementioned dimensions, and subsequently developed Key Allele-Specific PCR (KASP) markers. These markers underwent validation in hybrid populations of 'Hanfu' x 'Pink Lady' and 'Hanfu' x 'Honey Crisp'. Our findings underscored significant correlations between mechanical properties, water content, and cell size with crispness. Higher mechanical properties and water content, alongside smaller cell size, correlated with firmer flesh texture; moderate mechanical properties, and elevated water content and cell size, with crisper texture; whereas lower mechanical properties, water content, and cell size implied softer flesh.The study yielded KASP markers effectively reflecting flesh mechanical properties (SNP_24399345), water content (SNP_8667563), and cell size (SNP_15566229). Comprehensive analysis of these markers identified CC-CC-TT as an effective identifier of soft flesh individuals; while GG-TC-TT and GG-CC-TT combinations better represented individuals with harder flesh. The Crunchy subclass could be discerned by combinations of GG-TC-TC, GG-TC-CC, GG-TT-TC, and GG-TT-CC.
