We conducted experiments in natural populations of Solanum xanti in California, USA, to test the structure-function of the solanum staminal column and corolla. We excised the corolla of some flowers, the stamens of others, and painted stamens of others to assay pollinator response to changes in visible and UV patterns. Acrylic-painted staminal columns were yellow like the original anther color or concolorous with the corollas, and reflected light in the UV range instead of absorbing it. The flowers with stamens excised or with paint-altered UV patterns showed significantly lower fruit set, including those painted yellow. Experimental flowers with staminal columns only, i.e. with excised corollas, set fruit at the same rate as control flowers. Thus, the bee pollinators visit experimentally-altered flowers; they do not simply avoid aberrant flowers. While the combination of stamens and corolla are undoubtedly important visual attractants, our experiments support the underappreciated, and essential, role of the staminal column as a scaffold for the common, but distinctive, ‘buzz’ pollinators of solanums.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"34 1","pages":"632 - 639"},"PeriodicalIF":0.0,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85699632","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}

The objective of this study is to determine whether changes in species composition in coastal dune communities depend on the colonisation of a neophyte plant, Oenothera stucchii, or on concurrent processes that favour its colonisation. We hypothesised two scenarios: 1) a direct impact of O. stucchii on colonised communities, leading to displacement of native species; or 2) no direct impact of O. stucchii, i.e. the species colonises plant communities by exploiting disturbances that lead to the rearrangement of plant communities. We used the species-habitat network approach to identify potential drivers of changes in species composition, assuming that changes in the structure of the species-habitat network depend on the nature of the driving process. We demonstrated that changes in species composition in plant communities were due to species rearrangement, with colonised communities characterised by more homogeneous composition of species. We suggest that changes in plant communities may not depend on colonisation by O. stucchii per se, but on concomitant processes that affect coastal dune communities while promoting colonisation by O. stucchii.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"99 1","pages":"622 - 631"},"PeriodicalIF":0.0,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74173058","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}

We assessed the effects of mixed inoculation of five species of ERMF and five species of DSE on soil factors and growth and physiological functions of blueberry (Vaccinium corymbosum L. ‘O’Neal’) seedlings. The strains were isolated from blueberries in several regions of Guizhou Province. The fungi suspension root irrigation method was used to inoculate the seedlings. Six inoculation treatments, i.e. D (Cladosporium cladosporioides), N (Oidiodendron citrinum), D1N1 (D : N, 1:1), D1N2 (D : N, 1:2), D2N1 (D : N, 2:1) and CK (not inoculated) were conducted. Samples were collected two months after inoculation. The mixed inoculation of DSE and ERMF significantly promoted the height, stem diameter, shoot dry weight, total biomass, root activity and total chlorophyll content of the blueberry seedlings and enhanced their absorption capacity to mineral nutrients. The mixed inoculation also improved the activities of soil enzymes such as urease and acid phosphatase. The effect of mixed inoculation was better than that of single inoculation or CK. Combining the analysis results of the membership function, we concluded that D1N2 and D2N1 most significantly promoted the growth of blueberry seedlings. These data provide a basis for the potential application of DSE and ERMF mixed inoculation for promoting the growth of seedlings.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"29 1","pages":"497 - 506"},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75461704","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}

Global DNA methylation changes of mutants were compared and genes known to be involved in DNA methylation in plants were analyzed. Also, the expression of the telomerase reverse transcriptase (TERT) gene as a stress response indicator was analyzed in order to examine the effects of stress on the telomerase enzyme in the mutants. We found that mutants have a higher rate of hypomethylation than Col-0, under all conditions. According to the qPCR analysis, expression levels of Domains Rearranged Methylase 2 (DRM2), Polymerase IV (Pol IV) and Polymerase V (Pol V) genes were higher in mutants than Col-0 plants. Contrary to expectations for the TERT gene, there was an increase in expression in the stress-applied mutant plants. Taken together, results suggest that the RNA-directed DNA methylation (RdDM) pathway is enhanced in mutants in order to deal with the lack of DNA methylation in CG sites. In conclusion, we believe that the morphological and molecular data obtained regarding the effects of NaCl application to met1 mutants will help us to understand the epigenetic basis of stress mechanisms.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"68 1","pages":"507 - 515"},"PeriodicalIF":0.0,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85861662","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}

Cinnamic acid, gallic acid, protocatechuic acid and quercetin were phenolics found in all extracts. Acetone extract of S. amasiaca was the experiment containing the most phenolic compounds by containing 11 of them. While the highest total phenol content belonged to water extract of S. amasiaca (189.37 µg gallic acid equivalent/mg extract), water extract of O. bozakmanii had maximum total flavonoid rate (13.16 µg quercetin equivalent/mg extract). Acetone and water extracts of S. amasiaca showed higher DPPH scavenging (IC50: 43.40 and 18.71 mg/L, respectively) and metal chelating (IC50: 62.26 and 61.32 mg/L, respectively) activities compared to other plants. When viability rates of human cervical cancer cells (HeLa) treated with the extracts were investigated, the experiment with the highest cytotoxic effect was acetone extract of S. amasiaca (IC50: 45.10 mg/L).
