Allopolyploidy activates transposable elements (TEs) and causes genomic shock. Plant genomes can regulate gene expression by changing the epigenetic modification of TEs, but the mechanism for TEs to capture genes remains to be explored. Helitron TEs used the “peel-and-paste” mechanism to achieve gene capture. We identified 3,156 capture events and 326 donor genes of Helitron TEs in Brassica napus (AnAnCnCn). The donor genes captured by TEs were related to the number, length and location of their exons. The gene-capturing TEs carrying donor gene fragments were evenly distributed on the genome, and more than half of them were involved in the construction of pseudogenes, becoming the reserve force for polyploid evolution. Gene fragment copies enhanced information storage, providing opportunities for gene mutation and the formation of new genes. Simultaneously, the siRNAs targeting TEs may act on the donor genes due to siRNA crosstalk, and the gene methylation levels increased and the expression levels decreased. The genome sought a balance between sacrificing donor gene expression and silencing TEs, allowing TEs to hide in the genome. In addition, epigenetic modifications may temporarily relax the control of gene capture during allopolyploidization. Our study identified and characterized gene capture events in B. napus, analyzed the effects of DNA methylation and siRNA on gene capture events, and explored the regulation mechanism of gene expression by TEs epigenetic modification during allopolyploidization, which will contribute to understanding the formation and evolution mechanism of allopolyploidy.","PeriodicalId":13179,"journal":{"name":"Horticulture Research","volume":"18 1","pages":""},"PeriodicalIF":8.7,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the regulatory mechanisms underlying unicellular trichome development are well understood, those governing multicellular trichome formation remain largely unexplored. In this study, we reveal a new regulatory pathway involving the Hair3 (H3) and H4 genes, which encode C2H2 zinc finger proteins that participate in multicellular trichome development in tomato (Solanum lycopersicum). Using CRISPR-Cas9 to generate single- and double-knockout lines, we found that h3 and h4 single-mutant plants did not show altered trichome characteristics compared to wild-type plants. However, h3/h4 double-knockout plants displayed decreased densities of types I, VI, and VII trichomes, increased densities of types III and V trichomes, and reduced leaf and stem lengths of type I trichomes, revealing that H3 and H4 redundantly regulate trichome development. Notably, protein interaction assays demonstrated that H3 and H4 formed both homo- and hetero-dimers, supporting their cooperative role. Transcriptome and gene expression analyses identified H3 and H4 as key regulators of several genes involved in trichome development, including Woolly (Wo) and its downstream targets, such as Wox3b, MX1, H, and HD8. Protein-promoter assays showed that H3 and H4 did not directly bind to the Wo promoter but rather interacted with Wo, thereby enhancing the expression of Wo and Wox3b. These findings establish H3 and H4 as key regulators of trichome development and provide novel insights into the mechanisms controlling multicellular trichome development in tomato plants.","PeriodicalId":13179,"journal":{"name":"Horticulture Research","volume":"16 4 1","pages":""},"PeriodicalIF":8.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most triploid plants are with low fertility. Therefore, triploid offspring karyotypes’ variation pattern and phenotypic response remain poorly understood. Here, we employed three diploids with diverse genetic distances as male parents to cross-pollinate the female fertile triploid loquat Q24 to construct three experimental populations. The chromosome numbers of 93.82% of hybrid plants were 34~46 in three hybrid populations. All 168 aneuploids with 160 karyotypes and a small percentage of euploids were detected among 178 hybrids by the improved molecular karyotype analysis method. Further analysis revealed that when being transmitted to offspring, chromosome 5 of Q24 as disomy was with the highest frequency (&gt; 50%), while chromosome 12 was with the lowest frequency (≤ 30%). The frequency of Q24’s chromosomes being transmitted to offspring as disomy was influenced by the gene function on the chromosomes and the number of inter-chromosome collinear gene links. Whole genome resequencing showed that the Q24 alleles exhibited segregation distortions in the offspring aneuploid population. Transgenic experiments demonstrated that the EjRUN1 gene, which was on one segregation distortion region of Q24, promoted the seed viability of triploid Arabidopsis. Furthermore, chromosome number, dosage, and male parent genotype affected the aneuploid phenotype. These findings advance the understanding of genome genetic characteristics of triploid loquat, and provide a reference for germplasm innovation of loquat rapidly through triploid sexual reproduction.","PeriodicalId":13179,"journal":{"name":"Horticulture Research","volume":"104 1","pages":""},"PeriodicalIF":8.7,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different light qualities play differing roles in the rose floral transition, but the molecular mechanisms underlying their effects are not fully understood. Here we observed that red light suppresses rose flowering and increases the expression of Sensitivity to Red Light Reduced 1 (RcSRR1) compared with white light. Virus-induced gene silencing (VIGS) of RcSRR1 led to early flowering under white light and especially under red light, suggesting that this gene is a flowering repressor with a predominant function under red light. We determined that RcSRR1 interacts with the COP9 Signalosome Subunit 5B (RcCSN5B), while RcCSN5B, RcCOP1 and RcCO physically interact with each other. Furthermore, the RcCSN5B-induced deneddylation of Cullin4-RING E3 Ubiquitin Ligase (RcCRL4) in rose was reduced by the addition of RcSRR1, suggesting that the interaction between RcSRR1 and RcCSN5B relieves the deneddylation of the RcCRL4-COP1/SPA complex to enhance RcCO proteolysis, which subsequently suppresses the transcriptional activation of RcFT and ultimately flowering. Far-red Light Related Sequence Like 1 (RcFRSL3) was shown to specifically bind to the G-box motif of the RcSRR1 promoter to repress its transcription, removing its inhibition of RcFT expression and inducing flowering. Red light inhibited RcFRSL3 expression, thereby promoting the expression of RcSRR1 to inhibit flowering. Taken together, these results provide a previously uncharacterized mechanism by which the RcFRSL3–RcSRR1–RcCSN5B module targets RcCO stability to regulate flowering under different light conditions in rose plants.","PeriodicalId":13179,"journal":{"name":"Horticulture Research","volume":"74 1","pages":""},"PeriodicalIF":8.7,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The genetic basis of cold tolerance in pomegranates has remained elusive, largely due to the lack of high-quality genome assemblies for cold-tolerant varieties and comprehensive population-scale genomic studies. In this study, we addressed these challenges by assembling a high-quality chromosome-level reference genome for 'Sanbai', a pomegranate variety renowned for its freezing resistance, achieving an impressive contig N50 of 15.93 Mb. This robust assembly, enhanced by long-read sequencing of 38 pomegranate accessions, facilitated the identification of 14,239 polymorphic structural variants, revealing their critical roles in genomic diversity and population differentiation related to cold tolerance. Of particular significance was the discovery of a ~5.4-Mb inversion on chromosome 1, which emerged as an important factor affecting cold tolerance in pomegranate. Moreover, through the integration of bulked segregant analysis, differential selection analysis, and genetic transformation techniques, we identified and validated the interaction between the PgNAC12 transcription factor and PgCBF1, disclosing their pivotal roles in response to cold stress.

PbCYP78A6 has been shown to play a role in gibberellin (GA)-induced parthenocarpy in pears. However, the transcriptional response mechanism of PbCYP78A6 to GA remains unclear. In this study, using a yeast one-hybrid assay combined with co-expression analysis, PbMYB56 was initially identified as a transcription regulator of PbCYP78A6, which was further confirmed by electrophoretic mobility shift assay (EMSA) and dual-luciferase reporter assays. The biofunction of PbMYB56 was further verified using transient transgene tests, stable transgenic pear callus and tomato. PbMYB56 overexpression resulted in reduced cell death and higher fluorescence intensity after fluoresce diacetate (FDA) staining, as well as delayed fruit-drop by increasing PbCYP78A6 expression in un-pollinated pear fruitlets and callus. In contrast, silencing PbMYB56 caused cell death and early fruit-drop with decreased PbCYP78A6 expression. Moreover, after emasculation, heterologous overexpression of PbMYB56 induced parthenocarpy and enlarged seed size in pollinated tomato fruits. Silencing SlMYB56, a homolog of PbMYB56 in tomatoes, resulted in smaller fruit and seed size, and these traits were restored by co-overexpression with PbCYP78A6. Furthermore, we investigated the protein interaction between PbMYB56 and PbDELLA, which is crucial component of the GA signaling pathway. This interaction inhibited PbMYB56-induced transcriptional activation of PbCYP78A6.
