However, the impact of high-altitude climatic conditions, particularly temperature, on tea growth remains underexplored. To investigate, weather stations were deployed at three altitudes in southeastern Xizang to monitor spring temperature fluctuations: Medog (MD, 1200 m), Zayü (ZY, 1720 m), and Layue in Bayi District (BY, 2600 m). Field observations and meteorological data indicated that the milder spring temperatures in MD and ZY facilitated normal budburst and growth, whereas the lower temperatures in BY delayed budburst and resulted in leaf yellowing and browning. Comparative experiments revealed that seedlings exposed to fluctuating low temperatures (10°C/4°C) experienced the most severe cold injury and exhibited the lowest germination rates compared to seedlings under constant-temperature treatments. Transcriptome analysis uncovered differential expression of genes involved in chlorophyll degradation, lignin biosynthesis, and flavonoid pathways under cold stress. Functional characterization of the cold-induced transcription factor <i>CsABF2</i> revealed its central role in activating these pathways, as evidenced by antisense oligodeoxynucleotide (AsODN) silencing and promoter activation assays, to activate key downstream genes: <i>CsSGR1</i> (chlorophyll degradation), <i>CsPALa</i> (phenylpropanoid pathway), and <i>CsMYB6c</i> (flavonoid biosynthesis). These results provide mechanistic insights into how spring temperature variability at high altitudes impairs tea plant development and alters quality-related metabolites, offering a molecular basis for improving cold resilience in tea cultivation.</p>","PeriodicalId":57479,"journal":{"name":"园艺研究(英文)","volume":"13 1","pages":"uhaf279"},"PeriodicalIF":8.5,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12881854/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146144923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two main types of Munage: white fruit (WM) and red fruit (RM). However, the lack of a high-quality genomic resources has impeded effective breeding and restricted the potential for expanding these varieties to other growing regions. In this study, we assembled haplotype-resolved genome assemblies for WM and RM, alongside integrated whole genome resequencing (WGS) data and transcriptome data to illuminate the origin, private mutations and selection in Munage. Our analyses suggest that Munage likely shares a common ancestor with Eurasian grapes that originated in West Asia. Selective analysis between Munage clones and Eurasian grapes mapped genomic signals of selection in Munage grapes, with genes enriched in processes including cell maturation, plant epidermal cell differentiation, and root epidermal cell differentiation. We also identified 283 somatic mutation sites between WM and RM, along with differential selection on genome and expressed genes. These findings provide crucial genetic resources for investigating the genetics of the ancient Chinese grape variety, Munage, and will facilitate the genetic improvement in grapevine using this ancient cultivar as a gene donor.</p>","PeriodicalId":57479,"journal":{"name":"园艺研究(英文)","volume":"13 1","pages":"uhaf274"},"PeriodicalIF":9.5,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12881859/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146144968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
