These characters are, however, highly variable and species recognition challenging. In this paper, ribosomal DNA traits such as the internal transcribed spacer and the large subunit ribosomal gene were sequenced in several Scutellinia samples and, along with all available sequences on public database, used to improve the knowledge about taxonomy and phylogeny of this genus. Based on sequence similarity and trees topology, about 50 phylogenetic species were recognized and their phylogenetic relationships disclosed.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"7 1","pages":"188 - 198"},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78461777","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 used an extensive data-base with floristic relevés from Southern France to recalibrate indicator values for light (L), temperature (T), continentality (K), air humidity (A), soil moisture (F), pH (R), productivity (N), soil texture (G), soil organic matter content (O) and salinity (S). Values were recalibrated using average values from co-occurring plants, enabling to develop indicator values for species not yet evaluated previously. Recalibrated values are on a continuous scale and we add standard deviation, median, first and third quartile for each indicator value. Linear regression of average indicator values against measured factors showed higher correlation with recalibrated values compared to original indicator values for temperature, pH and nitrogen, and comparable R2 for moisture. Individual indicator systems performed better than a combination and applying different weighting procedures demonstrated the usefulness of inverse variance. We further illustrate graphically how recalibrated values and niche width increase ecological knowledge on plants.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"1 1","pages":"301 - 311"},"PeriodicalIF":0.0,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79617186","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 polluted substrates were composed of pyrite, dolomite, calcite, quartz, gypsum, and barite with iron sulfate, and iron oxide. Zn ore minerals (smithsonite) and muscovite detected mostly in the deeper soil layers. Zn was the most abundant metal in the substrate as well as plant tissues. Roots accumulated high metal concentrations (664.65–2710 Zn, 58.39–735.88 Pb, and 4.86–11.02 mg kg−1 Cd) reflecting high metal contamination in soil. The biological accumulation and translocation values were reported below one for all plant tissues. Pb, Zn and Cd Translocation Factor (TF) in needles ranged 0.03–0.32, 0.03–0.19, 0.04–0.14. Biological Concentration Factor (BCF) estimated up to 0.17, 0.18, and 0.19, respectively. The results indicate that P. halepensis is an excluder, tolerates high Zn, Pb, and Cd concentrations, restricts their accumulation and translocation to the aerial parts and may be applied for long-term phytostabilization and revegetation processes in abandoned mine tailing sites.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"18 1","pages":"272 - 285"},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80803370","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}

(Capparaceae) comprises edible plants and species with medicinal properties. Capparis spinosa is widely distributed in Europe, Africa, Asia and Oceania. This taxon forms a polymorphic species complex within that, several species and infraspecific taxa have been identified. We have focused on the leaf anatomy and micromorphology of Capparis taxa in Iran to find efficient diagnostic characters. Fresh samples of different taxa studied of C. spinosa were collected. Leaf-blade cross-sections and leaf surface were considered. Multivariate statistical analyses were used for illustrating the species and varieties similarities. Leaf anatomical features, such as midrib vascular bundle width and length, abaxial and adaxial epidermis thickness, abaxial and adaxial cuticle thickness, stomata depth, midrib outline on the adaxial surface, epicuticular wax, stomata average length, stomata number per leaf area and trichome type on the leaf surface were of diagnostic importance. As there is some degree of taxonomic confusion between different varieties of C. spinosa and mainly herbarium samples can provide stems and leaves for analyses, our anatomical study tries to overcome this problem. Results showed that selected features are of taxonomic importance in species and varieties separation. HIGHLIGHTS Leaf anatomy and micromorphology provided useful information to distinguish taxa within the C. spinosa group. C. cartilaginea with its thick leaves shows a distinct position from other taxa studied. Multi-layers of palisade parenchyma and occurrence of stomata on both sides of the leaf enable C. spinosa to increase its photosynthetic rate and decrease its temperature during drought conditions.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"14 1","pages":"262 - 271"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76413170","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}

Comparison of flower sets experiencing daily removal starting Day 1 with flowers that accumulated nectar for one or two days prior to daily removal revealed no discernible effect on the life-of-the-flower nectar production, sugar production and floral longevity. Flowers produce about the same cumulative volume of nectar during the two sexual phases. However, cumulative nectar sugar production is about 4 times higher during the male phase. Nectar standing crop ranged from 4–26.6 µl for Day 1 flowers and 0–8.7 µl for flowers from which nectar was removed the previous day. With daily removal of nectar, 21 of 40 flowers contained no nectar during the last day of the flower’s life. All unmanipulated flowers developed fruits (autonomous self-pollination). However, manual self-pollinations and manual cross-pollinations resulted in fruits that weighed significantly more and had significantly more seeds than fruits produced by autonomous self-pollination.

Comparatively few angiosperms exhibit ambophily and the significance of such a mechanism is not fully understood. During the present investigation, ambophily was studied in Olea ferruginea, over a period of three years. It is an andromonoecious and out-crossing tree species of the olive complex. The species is predominately pollinated by wind because it shows fruit set even when the insect pollinators were excluded. Moreover, a substantial amount of pollen was observed on the body parts of insect visitors and, comparatively, fruit set was enhanced in open-pollinated flowers receiving insect visitors. Floral structure of O. ferruginea displays floral traits favoring both wind and insect pollination. Furthermore, the flowers of this species were found to be visited by 20 insect species classified under three orders with Diptera and Hymenoptera being the leading pollen foragers. The results of linear regression of the hanging slide experiment showed that the dispersal of pollen grains decreased significantly with increasing distance from the canopy and the pollen density increased significantly with an increase in insect activity. The present work provides an insight to understand the ecological and evolutionary adaptations and consequences of spatio-temporal variation in plant – pollinator interactions. It is, therefore, useful for addressing both basic and applied questions in community structure and function including the evolution of floral traits, reproductive assurance, and the development of optimal conservation strategies.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"11 1","pages":"221 - 232"},"PeriodicalIF":0.0,"publicationDate":"2022-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81973579","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}

A key approach to detect and investigate the effect of climate and land use change on these ecosystems is represented by vegetation surveys. In this study, based on the resurvey of historical vegetation data, we assessed temporal beta-diversity patterns within and between subalpine and alpine vegetation types in the Dolomiti Bellunesi National Park. Resurvey was focussed on plots sampled in four main vegetation types: 1 and 2) Mesophytic and xerophytic grasslands on neutral or base-rich soils respectively dominated by Sesleria caerulea and Carex sempervirens and by Sesleria caerulea and Helictotrichon parlatorei; 3) Acidophytic grasslands dominated by Nardus stricta; 4) Snowbeds with dominance of dwarf willows (Salix herbacea or S. retusa) or Luzula alpinopilosa. Our results revealed a pattern of floristic homogenization in grasslands and snowbeds indicating a decreasing heterogeneity, both within and between different vegetation types that can be associated with different components of global change. The highest temporal beta diversity and floristic homogenization were detected in snowbeds. In general, the magnitude of temporal changes differ between communities, thus claiming for conservation activities that are tailored to each vegetation type.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"157 1","pages":"233 - 242"},"PeriodicalIF":0.0,"publicationDate":"2022-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81685521","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}
