Low environmental phosphate (Pi) levels typically result in reductions in both plant yield and quality. Currently, limited reports have been published on the response of WRKY transcription factors to low Pi exposure among woody plants that grow within the acidic soils of mountains. Herein, the <ce:italic>CoWRKY53</ce:italic> gene in <ce:italic>Camellia oleifera</ce:italic> was recognized, and its relevance under low Pi conditions was explored. The <ce:italic>CoWRKY53</ce:italic> gene was highly induced in root under low Pi stress. Specifically, CoWRKY53 is a nuclear protein through tobacco subcellular localization experiment, and it functions as a transcriptional activator. Moreover, it was demonstrated that overexpression of <ce:italic>CoWRKY53</ce:italic> in <ce:italic>Arabidopsis</ce:italic> and poplars enhanced the biomass, acid phosphatase activity, and Pi concentration of these plants by altering the architecture of their root systems (RSA). Additionally, <ce:italic>CoWRKY53</ce:italic> is directly associated with the W-box element of the <ce:italic>CoPHO1;H3</ce:italic> promoter by yeast hybridization to promote its transcription in order to positively modulate low Pi tolerance. <ce:italic>CoPHO1;H3</ce:italic> is known to complement <ce:italic>Arabidopsis</ce:italic> mutants. Thus, overexpression of <ce:italic>CoPHO1;H3</ce:italic> in <ce:italic>Arabidopsis</ce:italic> also promoted resistance to low Pi exposure. Together, these results suggest that <ce:italic>CoWRKY53</ce:italic> positively regulates <ce:italic>CoPHO1;H3</ce:italic> to increase low Pi tolerance in plants. These results provide an important theoretical basis for further breeding of elite germplasm resources with strong low phosphate tolerance.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"76 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059353","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}

Malic acid (MA), an organic acid naturally found in various fruits and plants, serves as a key regulator in the rooting process. However, the role of MA in AR formation has not been investigated in apples. Thus, this study investigates the effects of MA treatments on the AR morphology and the underlying physiological and molecular mechanisms in <ce:italic>MdWOX11</ce:italic>-OE transgenic and GL3 (wild type, WT) microshoots. Preliminary experiments revealed that control microshoots exhibited higher AR numbers compared to MA-treated microshoots, with a medium level of MA treatment markedly improving AR length. <ce:italic>MdWOX11</ce:italic>-OE microshoots outperformed WT microshoots in both AR quantity and length, especially at the medium MA level, indicating a greater response to MA. Morphological observations over time showed a significant increase in AR primordia in <ce:italic>MdWOX11</ce:italic>-OE microshoots by day 8, correlated with increased mitotic activity in cambial cells. Endogenous hormone analysis showed higher indole-3-acetic acid (IAA) levels and lower methyl jasmonate (JA-me) in <ce:italic>MdWOX11</ce:italic>-OE microshoots, suggesting hormonal influences on AR formation. A total of 4104 differentially expressed genes (DEGs) were identified through RNA sequencing, with significant enrichment of plant hormone signaling and stress-responsive pathways. Key auxin- and cytokinin-related DEGs revealed distinct expression patterns, illuminating the regulatory networks involved in AR formation. Moreover, DEGs related to the brassinosteroid (BR), gibberellin (GA), jasmonic acid (JA), abscisic acid (ABA), and ethylene (ET) signaling pathways were systematically analyzed, indicating complex regulatory networks. The identification of DEGs associated with starch and sucrose metabolism underscores the metabolic adjustments following adventitious rooting. These results suggest important insights into the molecular mechanisms regulating AR formation in response to MA treatment, highlighting the interplay between hormone signaling and genetic factors in improving adventitious rooting in apples.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"28 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009090","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}

Embryo rescue technology, with its advantages of increasing the proportion of seedless progeny and shortening the breeding cycle, has been widely applied in seedless grape breeding. To improve the efficiency of embryo rescue breeding in seedless grape, this study focused on rescuing and reusing abnormal seedlings generated during the process. By analyzing the influence of parental genotypes from 19 cross combinations on the formation of abnormal seedlings and employing both direct transformation and somatic embryogenesis for their rescue, the study investigated the effects of different abnormal seedling types and parental genotypes on rescue efficiency. Additionally, using the secondary embryos differentiated from the hypocotyls of abnormal seedlings in 3 cross combinations as experimental materials, the aim is to establish a somatic embryo regeneration system. The results revealed that the average proportion of abnormal seedlings (46.25 %) across the 19 cross combinations was significantly higher than that of normal seedlings (33.06 %). Among the abnormal seedling types, leaves without roots and cotyledon albinism were the most prevalent. Using the direct transformation method, the polycotyledonous type exhibited the highest rescue efficiency at 53.06 %, while the cross combination “Perlette × Huozhoucuiyu” achieved the highest abnormal seedling rescue rate of 81.11 %. Furthermore, secondary embryos derived from the hypocotyl of abnormal seedlings were capable of developing into normal seedlings, enabling the rescue of some abnormal seedlings. A cyclic somatic embryogenesis system was established for grape hypocotyls in the crosses “Melissa Seedless × Lüzhoubaoshi” and “Zitian Seedless × Melissa Seedless”. This approach not only significantly enhanced the efficiency of embryo rescue but also expanded the potential applications of abnormal seedlings in somatic regeneration research, providing valuable receptor materials for grape genetic transformation systems.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"40 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009071","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}

We previously identified 90 quantitative trait loci (QTLs) for apple fruit weight via bulked segregant analysis-seq. In this study, we identified 37 genome regions associated with apple fruit weight by genome-wide association study (GWAS) using 253 <ce:italic>Malus</ce:italic> accessions. We then developed 147 GenoBaits markers within the QTL intervals or association regions, of which nine were major-effect markers for small-fruit traits and exhibited complementary epistasis.
