Crop load, as defined by the amount of fruit produced per unit vegetative growth at dormancy, is a common measure of source:sink relationships used to evaluate vineyard production efficiency. We studied the impact of varying crop load on the transcriptome and metabolome of Pinot noir grape berries by comparing the development and ripening of fruit grown on vines with either 50 % or 75 % of their grape clusters removed immediately following fruit set compared to unthinned vines for three consecutive vintages. A clear impact on the general phenylpropanoid pathway resulting in a redistribution between stilbenes and anthocyanins was revealed under varying crop loads and consistent with the transcriptomic profiles of the corresponding branches. Moreover, we identified genes, such as <em>LBDIa3</em> and <em>AG2</em>, modulated by crop load around veraison, representing putative transcriptional key triggers of the berry ripening phase responding to differences in the vine source:sink ratio generated by the application of cluster thinning. Genes, specifically <em>EXPA1</em> and <em>EXPA18</em>, involved in softening and other crucial events of ripening initiation responded to crop load and likely influenced the progression of the ripening process. Beyond the major impacts represented by a shift of the onset and completion of ripening, we were able to highlight more subtle effects of the crop load, related to the rate at which the molecular and metabolic changes occur. This study asserts that grape metabolism and transcriptome are remarkably flexible, and that manipulations such as cluster thinning induce extensive, genome-wide changes in expression during berry development. The insights gained here pave the way to progress towards the construction of robust models depicting the molecular network that characterizes berry development and the impact of crop load on its molecular regulation.</p></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"338 ","pages":"Article 113644"},"PeriodicalIF":3.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0304423824007970/pdfft?md5=b626329913e929c28f15a1079c9a4a0e&pid=1-s2.0-S0304423824007970-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232626","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}

The protective effect of the CH in tomato fruit may be due to a direct fungitoxic action against the pathogen. It was found that the CH induced an immune response in tomato fruit via the accumulation of phenolic compounds. The level of phenolic compounds in the CH group was higher than in the untreated wound group from day 1 to 5, with a maximum reached on day 3 (113 mg-eq GA kg^-1).

Cerium oxide nanoparticles (CeO₂ NPs) have recently gained attention as a potential solution to environmental challenges, yet their application in grapevines remains understudied. This study examined the interaction between foliar-applied CeO₂ NPs (at concentrations of 0, 5, 50, and 500 mg L⁻¹) and drought stress (at 30% and 70% of field capacity humidity) in grapevine saplings. Among the different concentrations tested, 50 mg L⁻¹ CeO₂ NPs significantly improved the agronomic traits (e.g., shoot length, leaf area, shoot and root dry weights), photosynthetic parameters (stomatal conductance, chlorophyll a and chlorophyll <em>b</em>) and RWC of the grapevine saplings under drought stress. In parallel, CeO₂ NPs significantly induced the activity of compatible solutes and SOD, CAT and APX under drought stress conditions. Moreover, the availability of CeO₂ NPs alleviated drought stress-induced damage in grapevine saplings, as evidenced by decreased H₂O₂ (32.63%), EL (40.35%) and MDA (50.63%) levels. The molecular results revealed that CeO₂ NPs caused significant changes in gene expression under drought stress by reducing the expression of the <em>VvCLH1, VvCu/ZnSOD, VvRD29A</em> and <em>VvRBOHA</em> genes by 4.54-fold, 27.73-fold, 14.6-fold and 46.12-fold, respectively. These findings suggest that CeO₂ NPs applied via leaves enhance grapevine sapling resistance to drought-induced oxidative stress through cooperative enzymatic and nonenzymatic antioxidant mechanisms, influencing gene regulation. As a result, these findings revealed that CeO₂ NPs could be promising elicitor candidates for alleviating drought stress in grapevines.</p></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"338 ","pages":"Article 113606"},"PeriodicalIF":3.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzed the effect of wounded area and wound perimeter of laser marking patterns on the development of phloem, xylem, and callus using cross sections of single-leaf cuttings of <em>Rosa canina</em> 'Pfänder'. Four distinct laser patterns were designed and marked along the cutting base. Among these, three patterns were based on longitudinal strips, while one pattern was characterized by small squares, resulting in two distinct wound area levels and four wound perimeter levels. Periodic evaluations of stem sections showed that the development of phloem and xylem was significantly influenced by the pattern's geometry. Larger dimensions of xylem were associated with patterns of greater area and a smaller perimeter, while an increase in phloem was related to patterns of longer perimeter distributed in smaller areas. The maximum rooting success in wounded cuttings reached 44% in contrast to 9% observed in the control group in the absence of additional wounds. The development of vascular tissue was significantly correlated with adventitious rooting, with phloem being more closely linked with a Pearson coefficient of 0.92 compared to 0.30 for xylem. Additionally, a negative Pearson coefficient of −0.92 between the ratio area: perimeter and adventitious root formation showed that laser patterns with large wounded area with less borders led to a reduced rooting response. The results provide evidence of how wounded tissue contributes to the intrinsic development of adventitious roots and reveal the importance of proper wound dimensions.</p></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"338 ","pages":"Article 113647"},"PeriodicalIF":3.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0304423824008008/pdfft?md5=403ed90d891f6e7716b3cd8fb3705723&pid=1-s2.0-S0304423824008008-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232628","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}

The experimental design comprised four variables: two cut rose cultivars, namely Samurai and Jumilia; the utilization of NB at two different concentrations (0 and 20 mg <em>L</em>⁻¹); the foliar application of NSi at two different concentrations (0 and 2 ml <em>L</em>⁻¹); and foliar application of SWE at two different concentrations (0 and 1 ml <em>L</em>⁻¹). The quality and longevity of the flowers post-harvest were significantly enhanced by the treatments that were implemented. Comparing Jumilia cv to the control (31 days), the application of NB increased post-harvest life by 47.6 %. In addition, the petals exhibited the lowest Malondialdehyde concentrations. When NSi was applied to the flower, its quality improved by 43.7 % in comparison to the control. The combined treatment of NSi and SWE or individual application of NB resulted in the Samurai cv flower reaching its maximum length of 111.3 cm and 110.7 cm, respectively.
