A total of 53,225 unigenes were identified, including 11,684 differentially expressed genes (DEGs; 8,083 upregulated and 3,601 downregulated). Additionally, 44 gene ontology terms and 127 Kyoto Encyclopedia of Genes and Genomes pathways were significantly enriched among these DEGs. Genes related to glutathione metabolism, plant hormone signal transduction, peroxisome processes, sulfur metabolism, and flavonoid biosynthesis pathways were confirmed as relevant to the Cd response of P. sericea .

Using the Cocktail method, we defined consistent criteria for delimitation of the class, three orders, nine alliances, and 45 associations. Formal definitions were prepared using the summed cover and presence/absence information of species groups and individual dominant species. We created an expert system with a set of assignment rules that unambiguously classify relevés to a single unit at the given abstraction level of the Braun-Blanquet system in such a way that a relevé matched by the definition of a focal vegetation unit must be matched by definitions of all superior units. Of 11,535 relevés classified to Molinio-Arrhenatheretea, 36% were recognized at the association level, and 57% and 85% at the alliance and order level, respectively. All relevés were assigned unambiguously, meaning that a single relevé could not be assigned to more than one unit within the same hierarchical level (no overlap between vegetation units). This study is the first proposal of a hierarchically nested classification system that classifies grassland vegetation at different syntaxonomical levels unequivocally. It is important to create definitions for different syntaxonomical levels because the majority of vegetation patches do not fit to the associations, but can only be assigned to high-rank units such as alliance, order, or class.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48458280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a weighting method was used to control the soil water content to produce a soil water stress gradient. The effects of drought and rewatering on the changes in osmotic adjustment substance content, antioxidant enzyme activity, and photosynthetic characteristics of potted Dicranostigma henanensis seedlings were measured on Day 28 after the imposition of watering treatments and Day 7 after rewatering. During the drought stress process, the relative electrical conductivity, thiobarbituric acid, water use efficiency, and proline content displayed a continuously increasing trend. Further, the net photosynthetic rate, stomatal conductance, and transpiration rate constantly decreased, while the chlorophyll content first increased and then decreased. After rehydration, superoxide dismutase (EC 1.15.1.1) activity and photosynthetic parameters quickly recovered to the CK level (soil moisture is 75%–80% of the maximum water holding capacity in the field), indicating that D. henanensis plants have a strong ability to repair the damage caused by drought stress. In particular, the photosynthetic machinery may have sophisticated regulation and repair mechanisms, which may be associated with its stable photosystem. Collectively, our findings demonstrate that the D. henanensis plant has a strong ability to adapt to arid environments, and therefore could be an excellent ornamental flower for landscaping in arid and semiarid areas.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71055310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have been conducted in the Lesser Caucasus, west Georgia, and Turkish Caucasus. This study aims to represent and evaluate the cultural importance of wild vegetable plants and their patterns of use along the Georgia–Turkey border. During the transhumance period in the summers of 2017 and 2018, 104 participants (65 in Turkey and 39 in Georgia) were interviewed using a semistructured questionnaire. The Cultural Importance Index and Relative Frequency of Citation were used to compare the relative importance of species in each region. The use of 83 wild plant species from 23 plant families as vegetables was documented, with 45 species recorded in Georgia and 72 species in Turkey. One-third of the recorded wild plant species and 52 use instances out of 122 species-use combinations were shared on both sides of the border. Women and men had mentioned almost the same number of species, and there was a nonsignificant correlation between the plant knowledge and age. Although there were no significant differences in the plant parts used, the way people used plants as vegetables varied significantly across the border. Considering the floral similarity across the border, the number of species used in common and shared vegetable plant knowledge was quite low. There is not a significant difference between the two countries in terms of the most frequently cited and culturally important species ( Rumex , Urtica , and Polygonum spp.). However, the recognition of some of the most important shared species ( Heracleum , Chaerophyllum , Arctium , and Campanula spp.) diverged significantly in different administrative regions.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71055245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Czarnecka","doi":"10.5586/asbp.8942","DOIUrl":"https://doi.org/10.5586/asbp.8942","url":null,"abstract":"This paper was a part of studies conducted within an island population of the ragwort Senecio umbrosus (White Mt, southeastern Poland), a vulnerable element of xerothermic grasslands. Special attention was paid to the effects of expansive grass encroachment vs. grassland burning episodes on spatiotemporal patterns and life-stage structure of individuals in the population. The population traits were investigated nine times from 1990 to 2010, within three permanent patches differing in soil properties, initial floristic composition, grassland cover (particularly the cover of Brachypodium pinnatum), ragwort cover and density, shrub/tree cover influencing light intensity (full light–shadow), and grassland burning (zero–six episodes). There was a drastic decline in ragwort abundance within all the study patches accompanied by a decrease in the population clustering coefficient and a gradual equalization of the spatial distribution of ramets. The abundance was negatively correlated (PCA analysis) with an increase in B. pinnatum cover and positively correlated with the number of burning episodes, which temporarily delimited persistent litter cover and facilitated recruitment of new individuals. The decrease in ramet abundance ranged from 3.8 times (medium-high, moderately shadowed grassland; six cases of burning) to 8.3 times (high, dense, and shadowed grassland; four cases of burning). The patch of low, loose, sunlit, and never-burned grassland with the greatest initial density of ragwort (a 6.8-fold decrease in abundance) has evolved with time into a high and dense grassland with a greater coverage of B. pinnatum and Calamagrostis epigejos, additionally shaded by shrubs and young trees.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47981102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bryophyte diversity in sinkhole forests is also likely to be high. In this study, bryophytes of an underground forest sinkhole (UFS), and two forests (Forest Karst Mountain 1; FKM1) and (Forest Karst Mountain 2; FKM2) on the surface of the karst plateau were compared to understand the role of the sinkhole forest in the conservation of bryophyte diversity and the relationships between bryophyte diversity, environmental factors, and soil nutrients. Significantly more bryophyte taxa were recorded from the sinkhole forest (71 taxa, 36 genera, 23 families) than those in the forest on the plateau surface, which was the closest to the sinkhole (FKM1; 29 bryophyte taxa, 16 genera, 12 families), and even fewer bryophytes were found in the forest more distant to the sinkhole (FKM2; 22 taxa, 17 genera, eight families). Twenty-four liverwort taxa were collected from the sinkhole forest, two from the closest surface forest (FKM1) and none from the furthest surface forest (FKM2). Ninety-three percent of the bryophytes in karst mountain sinkhole were not found on surface forest. The diversity index trend was as follows: UFS > FKM1 > FKM2, and the evenness index trend was in the opposite direction as follows: UFS < FKM1 < FKM2. The beta diversity showed that the Jaccard index among the three forests was 0–0.25, reflecting a huge difference between the sinkhole forest and the two surface forests. Canonical correspondence analysis showed that light was the most important factor affecting the distribution of bryophytes in the sinkhole forest, while temperature and humidity were key factors for the distribution of bryophytes in the two surface forests. Further, soil parameters, namely, soil organic carbon, total nitrogen, total phosphorus, total potassium, alkali-hydrolyzed nitrogen, and available phosphorus changed gradually from UFS to FKM1 and to FKM2. The sinkhole forest, located in a landform with the unique negative topography enclosed by cliffs, and with a complex microenvironment, provides a natural refuge for bryophyte species in areas where forests have been negatively impacted by karst rocky desertification.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44445430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molnár V.","doi":"10.5586/asbp.89314","DOIUrl":"https://doi.org/10.5586/asbp.89314","url":null,"abstract":"Modern plant taxonomy is an extensive field that is increasingly benefiting from achievements in many other fields of the biological sciences, such as genetics, cytology, molecular biology, ecology, phytogeography, and paleobotany. The influence of these branches of science on plant taxonomy is expressed not only through a significant multiplication of information and detailed data but also through new phylogenetic concepts. Reconstructing phylogenetic compounds that unite all lines of evidence is a great challenge. The process of describing a new species is considered equivalent to generating a new hypothesis in phylogenetics. Hence, taxonomy and phylogenetics are inseparably connected with each other. Advances in taxonomy and phylogenetic taxonomy have led to this special issue of Acta Societatis Botanicorum Poloniae (ASBP), bringing together 13 articles from authors who responded to our invitation and call for papers from August 2019. The current issue is the fourth themed edition of ASBP and is preceded by the special issues of the journal published in 2012 (vol. 81, issue 4), 2014 (83/4), 2016 (85/4), and 2018 (87/4). The articles in this special issue cover a wide range of topics on vascular plants, bryophytes, and plant components in lichens. We would like to thank the authors who responded to our call and submitted their interesting contributions. In the opening paper, Podani (2020) presents results of studies on iconography used for plant systematics as well as a synthesis of current knowledge about plant systematics using a modern diagrammatic approach. Cladogram topology, phylogenetic classification and nomenclature, diversity of taxonomic groups, the geological timescale, and paleontological records have, for the first time, been brought together into one figure, the Coral of Plants. Another interesting article, written by Croat and Ortiz (2020), discusses the family Araceae, the most diverse in the NewWorld tropics, but are also found in the Old World tropics and northern temperate regions. These authors focused on the evolution of the morphological and ecological characteristics of this family that have enabled it to colonize diverse habitats. High species diversity and rates of endemism as well as the presence of large numbers of unknown species constitute the principal characteristics of this family. Four of the articles consider phylogenetic relationships and divergence times of species or groups of species of vascular plants in Central Europe. Boroń et al. (2020) make an interesting contribution to a taxonomically difficult group of Angiosperms, namely, Aconitum subgen. Aconitum (Ranunculaceae), employing two independent genetic markers. These authors present hypotheses about the origin, estimated divergence time, and genetic differentiation of European and Asian diploids and tetraploids.
