To address these challenges, an integrated soil nutrient management strategy is crucial. Using pomelo orchard as a case, a two-year field experiment was conducted with three treatments, i.e., FP (NPK fertilizer overused), OPT (balanced NPK fertilization), and OPT + C (balanced NPK with organic amendments). The aim was to assess the potential benefits of balancing nutrient inputs and incorporating organic amendments for enhancing efficiency and quality production. The results revealed that, compared to the FP treatment, the OPT treatment significantly reduced environmental footprints: 92.7% for carbon, 85.4% for nitrogen, and 99.9% for phosphorus, while simultaneously improving the benefit-cost ratio by 80.8%. Furthermore, the OPT + C treatment outperformed the OPT treatment by improving fruit yield (by 8.7%) and fruit quality, as indicated by the lowest titratable acidity (0.62%) and highest vitamin C content (403.2 mg kg<ce:sup loc=\"post\">−1</ce:sup>). Structural equation modeling revealed that balanced NPK fertilization improved root morphology, achieving a synergistic balance between economic and environmental efficiency while maintaining pomelo yield. Additionally, organic amendments positively influenced soil properties and enzyme activities, promoting a synergistic increase in both pomelo yield and quality. In conclusion, the combination of balanced NPK and organic amendments led to synergistic improvements in pomelo yield, fruit quality, environmental footprints, and benefit-cost ratio. These findings provide a valuable framework for improving orchard efficiency and quality production through an integrated soil nutrient management strategy.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"22 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093841","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}

This review synthesizes recent advances in understanding their roles in perennial growth cycles and horticultural trait regulation, with a focus on their contributions to fruit development, secondary growth, and complex environmental adaptation. Structurally, C2H2-ZFPs harbor conserved zinc-coordinating motifs (C2H2 domains) and regulatory domains, enabling precise transcriptional control of developmental processes. In woody and horticultural plants, they integrate hormonal signals (e.g., auxin, ABA) and environmental cues (e.g., drought, photoperiod) to regulate seasonal dormancy and flowering timing in horticultural species, cambial activity for wood formation, and fruit ripening processes. Under abiotic stress, C2H2-ZFPs act as key modulators in ABA-dependent and independent pathways, governing osmotic balance, redox homeostasis, and stress memory. Meanwhile, emerging evidence also highlights their involvement in biotic stress responses. However, dissecting their regulatory networks in woody and horticultural species remains challenging due to genomic redundancy and complex regulatory layers. Future research should leverage multi-omics approaches and CRISPR-based tools to uncover their functional redundancy and species-specific adaptations, thereby advancing sustainable forestry and precision horticulture breeding under climate change.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"66 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059395","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}

Taken together, our study elucidates the critical role of the PomiR164–<ce:italic>PoLBD25</ce:italic> module in regulating the flowering time in peony, providing a theoretical basis for flowering control and genetic breeding in peony.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":"1 1","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059351","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}

{"title":"Dedifferentiation and redifferentiation: The developing cell fate transition of plants","authors":"Asia Maqbool, Mengxiao Lu, Noor Muhammad, Naila Mir Baz, Mengjun Liu, Zhiguo Liu, Lixin Wang","doi":"10.1016/j.hpj.2025.08.005","DOIUrl":"https://doi.org/10.1016/j.hpj.2025.08.005","url":null,"abstract":"Plant cells retain the ability for cellular reprogramming, including totipotency and pluripotency, enabling them to revert their cell fate from differentiated to dedifferentiated one and subsequently redifferentiate under specific physiological and environmental cues. In response to these cues, endogenous phytohormones, genetic landscapes, and epigenetic remodeling play a significant role in initiating the reprogramming of somatic cells and re-establishment of an organized structure. Detailed studies on dedifferentiation have gradually unraveled the involvement of stem-like cells during early callus formation, along with the existence of QC-like transcriptional features in the middle cell layer of callus, which exhibits organ regeneration ability. Tracking natural variations and real-time regeneration dynamics across species, combined with single-cell RNA sequencing, will enable the identification of key developmental regulators and small peptides. These breakthroughs can be applied to enhance regeneration efficiency, improve transformation in recalcitrant species, and accelerate next-generation crop development. The current review summarizes the longstanding history and ongoing research progress in two pathways: dedifferentiation and redifferentiation. It also highlights how hormonal effects on the genetic factors and provides insights into how genetic signatures interact with epigenetic landscapes to drive these processes. It highlights the potential applications of developmental regulators for efficient gene transformation to enhance plant genetic engineering, while also addressing fundamental questions and identifying research gaps to guide future studies.","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":"145059352","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}
