The plant hormone auxin has varying effects across different species, however, the molecular mechanism by which auxin regulates the softening process of ‘Docteur Jules Guyot’ pear remains unclear. In this study, we treated post-harvest pear fruit with IAA and compared them with the control group. We observed that fruit firmness declined more rapidly in the IAA-treated group, with a corresponding rise in ethylene release compared to the control. Additionally, the IAA treatment increased both water-soluble and ionically soluble pectin while the content of covalently bound pectin decreased. This was accompanied by a significant enhancement in pectinase activity, in addition, through transcriptome analysis, we identified 15 pectinase-encoding genes and 16 candidate genes related to IAA. The results of gene expression and correlation analysis showed that IAA treatment induced the expression of <em>PcGH3.1</em> and <em>PcILL3</em>, and these two genes exhibited a significant positive correlation with the pectinase encoding genes <em>PcPG1, PcPG3, PcPL8, PcPL15, PcPL18</em>, and <em>PcPME63</em>. Therefore, IAA treatment regulates the expression of multiple pectinase-encoding genes, which in turn enhances pectinase activity and accelerates the postharvest softening process in ‘Docteur Jules Guyot’ pear.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"341 ","pages":"Article 113965"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research on nitrogen absorption and stress resistance mediated by the <em>NRT1</em> gene family has not yet been undertaken in coconut. In this study, multiple bioinformatics tools were employed to identify 67 members of the <em>NRT1</em> gene family in dwarf coconuts, which can be categorized into 8 subfamilies. The analysis also determined the <em>NRT1</em> genes' molecular weight, chromosome distribution, subcellular localization, transmembrane structure, and conserved structural domains. In addition, it was discovered that the proline concentration in dwarf coconut leaves significantly increased after 8 h and 7 days of cold treatment. Transcriptome and qPCR analysis revealed that after 7 days of cold stress, the expression levels of the coconut <em>CnNRT1</em> genes generally decreased significantly. This suggests that cold stress may inhibit the absorption and transport of nitrate nitrogen in coconuts. In a combined examination of tall and dwarf coconut varieties, it was observed that <em>CnNRT1.5, CnNRT1.8, CnNRT1.13</em>, and <em>CnNRT1.17</em> genes responded promptly to cold stress signals after 8 h, showing heightened expression levels in various plant parts such as roots, stems, floral organs, and fruit peels. This observation suggests a potential involvement of nitrate nitrogen, regulated by <em>CnNRT1</em> genes, in the coconut's ability to adapt to cold stress. This further suggests that nitrate nitrogen mediated by <em>CnNRT1</em> <em>s</em> may participate in the coconut's adaptation to cold stress.

Results showed that nutrient solution recycling enhanced water use efficiency but led to nutrient imbalances in remaining solution: nitrogen (N), phosphorus (P), and potassium (K) were rapidly absorbed independent of plant transpiration, while magnesium (Mg), sulfur (S), and calcium (Ca) were absorbed more slowly. These imbalances resulted in morphological changes, as leaf area were reduced by 22.3 % in C₃ compared to C₁, while primary root length increased by 34.6 %. Middle-position leaves, which are critical for photosynthesis, exhibited reduced light interception and photosynthetic capacity under nutrient recycling conditions. To optimize nutrient management, N, P, and K should be supplemented in multiple doses based on total plant demand, while Mg, S, and Ca should be supplied at standard concentrations with water.

In recent decades, global temperature increases of over 2 °C above pre-industrial levels have impacted phenology, yield, sugar accumulation, and harvest time, ultimately affecting wine quality. Heat stress (&gt; 35 °C) for 3–5 consecutive days from high temperatures and excessive solar radiation can disrupt the vine's physiology, prompting accelerated sugar accumulation in berries by 20–30%, a consequence of multiple factors including berry dehydration and high alcohol concentrations that compromise wine quality and typicity. Techniques such as late winter pruning, nanoparticle/antitranspirant application, netting (reducing solar radiation by 20–40%), training systems, and cluster thinning effectively reduce excessive fruit surface temperatures and modulate water loss, light exposure, and air circulation. Additionally, photo-selective shading can decrease berry cell death by 30–50%. Combining various methods can enhance yield and quality in hot, dry climates like the Mediterranean Basin by balancing the sink-source ratio. Adopting a holistic approach by combining traditional and modern techniques will aid viticulture in adapting to climate change. Hence, integrating artificial intelligence (AI) based sensors, unmanned aerial vehicles (UAV's), and machine learning algorithms enables precise vineyard monitoring for irrigation and canopy status. Canopy management practices have evolved across centuries to optimize sunlight interception, photosynthetic capacity, and cluster zone microclimate, mitigating negative climate impacts. The choice of trellising in modern times has shifted from traditional, locally adapted methods towards more productive systems supported by fertigation and fungicides in the pursuit of increased yield. We suggest a holistic, microclimate/site-driven approach that integrates varietal biodiversity, precision irrigation, and sustainable soil management, which, even if not supported by AI-driven monitoring, can improve the balance between yield, quality, and vine resilience in a changing climate.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"341 ","pages":"Article 113998"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143166475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
