While its role in primary cell walls is well established, its specific functions and regulatory mechanisms in secondary xylem (i.e., wood formation) remain poorly understood. This study investigated the role of pectin methylesterification in wood development. We discovered that both low- and high-methylesterified homogalacturonan (HG) are abundant in the cambium and expanding xylem regions of secondary vascular tissues. Using integrative bioinformatics approaches, we identified 75 <em>PtrPMEs</em> and 61 <em>PtrPMEIs</em> within the <em>Populus trichocarpa</em> genome, many of which are highly expressed during wood formation. Notably, several <em>PtrPMEs</em> and <em>PtrPMEIs</em> with similar expression patterns are capable of interacting, suggesting post-translational regulation of PME activity during wood formation. Specifically, the highly expressed <em>PtrPME10</em>, <em>PtrPME70</em>, <em>PtrPMEI50,</em> and <em>PtrPMEI58</em> during secondary cell wall deposition were co-expressed with genes involved in monolignol polymerization across 51 poplar tissues and organs, implying a putative role in lignin biosynthesis. Furthermore, overexpression of the <em>Populus</em> ortholog of <em>PtrPME45</em> in <em>P. davidiana ​× ​bolleana</em> led to increased demethylesterification of HG, resulting in reduced lengths and widths of vessel and fiber cells in secondary xylem. Our study uncovers specific roles of PME in wood formation and elucidates regulatory mechanisms controlling PME activity during wood development. These findings on the interplay between PME and lignin biosynthesis provide a potential strategy for genetic improvement of woody plants, with implications for forestry and bioenergy applications.</div></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"3 3","pages":"Article 100102"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we analyzed the genomic characteristics of 26 <em>Malus</em> accessions, identified and classified their transcription factor (TF) families, and conducted a comprehensive pangenome-wide investigation of the TCP gene family across these accessions. Our findings revealed a strong positive correlation between genome size and transposable element (TE) content, suggesting TEs play a role in genome expansion. TF profiling showed significant variation in the abundance of certain families among different accessions. Specifically, 932 TCP genes were grouped into three subfamilies (PCF, CIN, and CYC/TB1) with a consistent compositional pattern. Orthologous gene group (OGG) analysis among the 26 <em>Malus</em> accessions revealed that core TCP genes were relatively conserved in gene count and possessed longer gene sequences and coding sequences (CDS). Synteny analyses indicated strong evolutionary conservation, with purifying selection acting on most TCP genes. Functional enrichment analysis highlighted the functional diversity within the TCP gene family. Moreover, transcriptomic analyses during adventitious shoot (AS) regeneration showed that core TCP genes were expressed at higher levels than non-core ones and identified some candidate TCP genes potentially involved in regulating AS formation. This study provides valuable insights into the evolutionary conservation and functional diversity of the TCP gene family, revealing its potential regulatory roles in AS regeneration in apple.</div></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"3 3","pages":"Article 100101"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While mushrooms have been suggested as potential agents for mitigating climate change, the effects of climate change on mushroom production remain largely unexplored. Here, we review and analyze the potential impacts of climate change on the production of both cultivated and wild edible and medicinal mushrooms, with a focus on the impacts of changing temperature and precipitation. First, we review global temperature and precipitation scenarios projected by 2100. Most climate scientists predict that global temperature will continue to rise gradually and precipitation distribution will become increasingly uneven in the future. Second, our analyses suggest that these environmental shifts will negatively impact the productivity of most cultivated mushrooms in multiple ways, including restricted substrate supplies, damage from pests and pathogens, and high electrical expenditures, etc. Third, some wild mushrooms may benefit from warmer and more humid conditions in certain regions, leading to increased mycelial growth and fruiting. However, hotter and drier environments in other regions, as projected for the future, will likely suffer decreasing yields for most mushrooms. For many wild gourmet mushroom species, their suitable habitats may change, with the majority predicted to experience habitat shrinkage, resulting in an overall decrease in productivity. Aside from challenges, we also discuss opportunities, including incorporating smart technologies for monitoring environmental factors, utilizing artificial intelligence for predictive analytics, and automating tasks such as irrigation and cooling/heating. We note that long-term monitoring across multiple ecological zones is needed to accurately quantify the impacts of global climate change on mushroom production and fine-tune strategies for sustainable mushroom cultivation.</div></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"3 3","pages":"Article 100091"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SVV employs diverse strategies to evade innate immunity, primarily through 3C protease, which targets host antiviral proteins to antagonize IFN-I signaling. Additionally, SVV hijacks autophagy, apoptosis, and pyroptosis to facilitate its own replication.

Current detection methods require destructive sampling, which is time-consuming and labor-intensive. Therefore, they are not suitable for high-volume inspection of individual products during postharvest handling. This study presents an innovative hyperspectral imaging-based approach to detect SWD infestation in highbush blueberry fruit. Two benchtop hyperspectral imaging systems in reflectance mode, operating in the visible-near-infrared (Vis-NIR, 400–1000 ​nm) and short-wavelength infrared (SWIR, 900–1700 ​nm) ranges, respectively, were in-house assembled for acquiring images of 945 (including 706 healthy and 235 infested) blueberry samples hand-picked from orchards. Hyperspectral imagery was processed to segment blueberries and extract mean spectra from individual samples. Infested blueberries showed lower spectral reflectance in the region of 750–1350 ​nm than normal samples. Baseline models were built using six different classifiers for sample classification, and the models based on partial least squares discriminant analysis (PLS-DA) yielded the best overall accuracy of 90.2 ​% and 92.5 ​% for the Vis-NIR and SWIR systems, respectively, with the corresponding recall rates of 74.2 ​% and 80.6 ​% for infested fruit. Three alternative modeling pipelines were proposed by implementing oversampling of the minority infested fruit class and waveband selection, through an exhaustive search for optimal methods, resulting in improved detection performance. Among the optimization strategies, oversampling proved more effective than waveband selection for enhancing model performance, and their combination (oversampling followed by waveband selection) yielded the best classification, with PLS-DA remaining the best classifier.
