Marsupella subemarginata Bakalin & Fedosov is a semi-cryptic Eurasian species. Recently, it has been found in the Far East (Kamchatka and Japan) and Swiss Alps, as well as the Giant Mountains (Sudetes, Czech Republic). The plant was also observed in the Carpathians for the first time. A revision of the herbarium collections of M. emarginata (Ehrh.) Dumort. consisting of 102 specimens from the Polish and Slovak Tatra Mountains revealed the occurrence of M. subemarginata at 24 localities, eight of which were in the Polish Tatras. Most of the localities of this species were concentrated in the High Tatras, and only four sites were discovered in the Western Tatras. Marsupella subemarginata has been briefly characterized morphologically and illustrated. The habitat requirements of the species have been described in detail, and the floristic composition of its phytocoenoses has been shown in a phytosociological table consisting of 10 relevés. Marsupella subemarginata is a valuable addition to the liverwort flora of Poland and Slovakia, which currently consist of 241 and 232 species, respectively. Currently, the liverwort flora of the Tatras comprises 195 species, including 185 species in Poland and 186 species in Slovakia.

Over the last 40 years, in vitro tissue culture has developed dynamically and has become a popular technique for scientific research in the field of biology. Initially, studies were carried out to develop procedures to obtain callus cultures, cell suspensions, and protoplasts of various plant species. Over time, these cultures have been used to analyze the course of processes and mechanisms that occur at the cellular level, including the course of embryological development, formation of cellular structures, polyploidization, signal transduction, gene expression, and responses to various stress factors. In a minireview, different nutritional, hormonal, atmospheric, and light conditions occurring in in vitro cultures, which are stressful conditions compared to those in ex vitro plant culture, were discussed. In this review, some examples of physiological studies conducted on in vitro culture by Polish scientists are presented, including studies carried out to optimize the composition of media that induce callus and plant regeneration; determine the use of in vitro culture for the preservation of endangered plant species; understand the mechanisms of resistance responses to pathogens, salinity, nutritional stress, and low temperatures; and determine the potential production of plants with different chemical compositions. The potential of sterile plant culture is large and beyond the scope of its current use. Therefore, the number and variety of applications of these cultures will be significantly greater in the future.

Fritillaria imperialis is a bulbous plant that has increased commercial value and contributes to rural development in Turkey. It is widely utilized in traditional medicine and pharmacy, and has great potential for use in modern pharmaceuticals in the future. As the effects of climate change on this plant have not been documented, this study aimed to understand how climate change might affect F. imperialis . The methodology of the study was divided into three steps: ( i ) database development, including the current distribution zones of F. imperialis and climatic parameters such as temperature and precipitation data; ( ii ) determination of the plant’s temperature and precipitation requirements; and ( iii ) Ecocrop’s plant climate suitability modeling (PCSM). As a result of the study, it was determined that climatic suitability would decrease below 20% in the plant’s current distribution area between 2,000 m and 3,000 m altitude. For the zones between 500–1,000 m altitude, the climatic suitability will be as high as 100%. Although there are zones where climatic suitability will increase by 2070, the general trend shows that suitability will decrease. This change in the plant ecosystem is explained by the decreased winter precipitation and snowfall but increased temperature and evaporation at higher altitudes. Fritillaria imperialis is expected to shift its geographic distribution to lower altitudes because of climate change.

Plant cell and organ cultures are potential sources of valuable secondary metabolites that can be used as food additives, nutraceuticals, cosmeceuticals, and pharmaceuticals. Phytochemical biosynthesis in various in vitro plant cultures, in contrast to that in planta, is independent of environmental conditions and free from quality fluctuations. Pharmaceutical application of plant biotechnology is of interest to almost all departments of the Faculty of Pharmacy and Institute of Pharmacology in Poland with a botanical profile (Pharmaceutical Botany, Pharmacognosy, and Pharmacology). This study discusses the advances in plant biotechnology for the production of known metabolites and/or biosynthesis of novel compounds in plant cell and organ in vitro cultures in several scientific centers in Poland.

Plants experience a range of light intensities and qualities in their environment. Leaves are subjected to spatial and temporal gradients in incident light, which has major consequences in the photosynthetic carbon assimilation. Plants acclimate to light by developing a range of mechanisms, from adjustments in leaf morphology to changes in the photosynthetic apparatus stoichiometry. In C4 plants, light intensity is a major limiting factor for photosynthesis at optimum temperatures. Under limiting light, it is not clear if all of factors (e.g., temperature, mineral nutrition, water supply) are co-limiting or if there is one primary limitation. Differences in light quality and intensity have a profound impact on C4 photosynthesis, where pathways require metabolic coordination of the mesophyll and bundle sheath cycles. Changes in the linear versus cyclic electron flux in maize (NADP-malic enzyme C4 subtype) in the mesophyll and bundle sheath chloroplasts in response to light may lead to an imbalance in the coordination of the C3 and C4 pathways. Additionally, the rearrangement of the thylakoid complexes of both types of chloroplasts in maize optimizes the light energy distribution between the mesophyll and bundle sheath cells and may also participate in energy dissipation. This review aims to highlight the changes in the understanding of the functions of photosystem II in maize bundle sheath chloroplasts and the role of super and megacomplexes in the thylakoids.

The altitude of alpine timberline elevation has been considered to correlate with certain climatic factors. Many related isotherms (e.g., warmest month 10 °C isotherm) have been proposed to explain the altitudinal distribution of alpine timberline at the global scale. However, any climatic index actually has a wide range at the alpine timberline position worldwide. The altitudinal position of the alpine timberline is related to far more than just one climatic factor. Therefore, we developed a multivariable model for timberline elevation variability by collecting data from 473 timberline sites on the Eurasian continent. We analyzed 12 climatic variables that potentially account for timberline variation. Principal component and regression analyses were used to mine four climatic variables. The mean temperature of the warmest month (MTWM), mean temperature of the coldest month (MTCM), climatic continentality (K), and annual precipitation (AP) explained 95% of the variability of timberline elevation. MTWM, MTCM, K, and AP contributed 18%, 41.28%, 34.9%, and 5.82%, respectively, to the altitudinal distribution of alpine timberline on the whole continent; 20%, 44%, 28.86%, and 7.14% in the eastern continent; and 17.71%, 39.79%, 40.21%, and 2.29% in the western continent. We showed that MTWM, MTCM, K, and AP are deterministic factors for the altitudinal distribution of alpine timberline in the Eurasian continent. MTCM and K contributed to explaining the altitudinal distribution of timberline both in the entire, eastern, and western parts of the Eurasian continent. Our research highlights the significance of MTCM for the altitudinal distribution of timberline.

Archaeobotany is the study of relationships between humans and the plant world in the past based on the analysis of plant remains preserved at archaeological sites. These studies provide us an opportunity to elucidate the history of farming economy based on transformations of plants and the natural environment caused by human activities. The present review aims to track the history of development of archaeobotanical studies in Poland, which have influenced our contemporary way of perceiving the past, as well as to present the selected and most important achievements in this field. Specifically, we emphasize the enormous contribution of Polish studies to broadening our understanding of the botanical past of Europe and the world. To the best of our knowledge, this work represents the first comprehensive attempt to summarize over a hundred-year-old activity of archaeobotanists in Poland.

This work focuses on the achievements of Polish researchers in the field of vegetative reproduction of plants under in vitro conditions. For more than 50 years, micropropagation methods have been used in Poland whenever vegetative reproduction is necessary. Most perennial horticultural crops, such as fruit plants, the majority of ornamental geophytes, and some vegetables (e.g., rhubarb and horseradish), require clonal reproduction owing to their high heterozygosity, i.e., their offsprings when reproduced from seeds, do not repeat the parental characteristics. Various goals have been pursued in the development of regenerative and in vitro propagation systems for each of the aforementioned groups of plants, such as pathogen elimination, reproduction of healthy plants, rapid multiplication of newly obtained valuable breeding lines and cultivars, and breeding to obtain polyploids, haploids, and doubled haploids. Owing to the growing interest of researchers and plant producers in environmentally friendly technologies, one of the sections is devoted to the issue of biotization of micropropagated plants.

The Stipa breviflora desert steppe is an important component of the Eurasian steppe, and its ecosystem functions are directly affected by changes in the individual functional traits of S. breviflora . Based on 14 years of data from the grazing experiment in S. breviflora desert steppe, we investigated changes in the individual tillering traits of S. breviflora in response to four levels (none, light, moderate, heavy) of long-term grazing. The results showed that: ( i ) long-term grazing resulted in a greater decrease in species richness and increased biomass contribution of S. breviflora in the communities; ( ii ) long-term grazing resulted in significant differences in aboveground/belowground plant tillering functional traits and their relationships under different grazing intensities; ( iii ) the leaf biomass of S. breviflora tillering individuals was strongly dependent on leaf number, while the change in root biomass was strongly dependent on the total root length, specific root length, root furcation number, and root crossing number. The response of S. breviflora biomass to grazing intensity and its relation to tillering individual traits revealed that long-term grazing leads to vast tillering in S. breviflora tussock and significant changes in S. breviflora tillering traits, which will have a profound influence on the function of the desert grassland ecosystem.

The results showed that: (\u0000 \u0000 i\u0000 \u0000 ) long-term grazing resulted in a greater decrease in species richness and increased biomass contribution of\u0000 S. breviflora\u0000 in the communities; (\u0000 \u0000 ii\u0000 \u0000 ) long-term grazing resulted in significant differences in aboveground/belowground plant tillering functional traits and their relationships under different grazing intensities; (\u0000 \u0000 iii\u0000 \u0000 ) the leaf biomass of\u0000 S. breviflora\u0000 tillering individuals was strongly dependent on leaf number, while the change in root biomass was strongly dependent on the total root length, specific root length, root furcation number, and root crossing number. The response of\u0000 S. breviflora\u0000 biomass to grazing intensity and its relation to tillering individual traits revealed that long-term grazing leads to vast tillering in\u0000 S. breviflora\u0000 tussock and significant changes in\u0000 S. breviflora\u0000 tillering traits, which will have a profound influence on the function of the desert grassland ecosystem.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48904486","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}
