Buckwheat in Tissue Culture Research: Current Status and Future Perspectives
Get PDFBuckwheat is a member of a genus of 23 species, where the two most common species
are Fagopyrum esculentum (common buckwheat) and Fagopyrum tataricum (Tartary buckwheat). This
pseudocereal is a source of micro and macro nutrients, such as gluten-free proteins and amino acids,
fatty acids, bioactive compounds, dietary fibre, fagopyrins, vitamins and minerals. It is gaining
increasing attention due to its health-promoting properties. Buckwheat is widely susceptible to
in vitro conditions which are used to study plantlet regeneration, callus induction, organogenesis,
somatic embryogenesis, and the synthesis of phenolic compounds. This review summarises the
development of buckwheat in in vitro culture and describes protocols for the regeneration of plantlets
from various explants and differing concentrations of plant growth regulators. It also describes callus
induction protocols as well as the role of calli in plantlet regeneration. Protocols for establishing
hairy root cultures with the use of Agrobacterium rhizogens are useful in the synthesis of secondary
metabolites, as well as protocols used for transgenic plants. The review also focuses on the future
prospects of buckwheat in tissue culture and the challenges researchers are addressing
Hypsometric changes in urban areas resulting from multiple years of mining activity
Get PDFThe impact of multiple years of underground mining of minerals on changes in the elevation of an urban area has been evaluated using the case study of Bytom in southern Poland. Between 1883 and 2011, that city experienced changes in absolute minimum (from 250.0 to 243.0 m a.s.l.) and maximum (from 340.0 to 348.4 m a.s.l.) elevations. During that period, the difference between minimum and maximum elevations increased from 90.0 to 105.4 m. The consequence of underground mining has been the formation of extensive subsidence basins with a maximum depth of 35 m. Where the terrain became raised, its elevation rose most commonly by 1.1 m to 5.0 m, with maximum increase in elevation caused by human activity amounting to 35 m. The rate of anthropogenic subsidence in the city between 1883 and 2011 averaged 43 mm/year (5.5 m over the study period)
O (nie)zakorzenieniu w śląskości. Nowy Śląsk jako przestrzeń tworzenia się biografii
No full textNew Silesia was the result of a communist project, that was implementing
the vision of building a socialist world and creating a new man. This process
had fundamental importance for people coming in masses to Upper Silesia to
work and for their biographies to be constructed. In the article I present a trajectory
reconstruction of the identity of a woman participating in the research. Her
biography is an example of the identity processes related to the arrival and life in
the „forming” city
Sugarcane Root Transcriptome Analysis Revealed the Role of Plant Hormones in the Colonization of an Endophytic Diazotroph
No full textSome sugarcane germplasms can absorb higher amounts of nitrogen via atmospheric
nitrogen fixation through the bacterial diazotrophs. Most endophytic diazotrophs usually
penetrate through the root, colonize inside the plant, and fix the nitrogen. To assess
the plant’s bacterial association during root colonization, strain GXS16 was tagged with
a plasmid-bear green fluorescent protein (GFP) gene. The results demonstrated that
the strain can colonize roots all the way to the maturation zone. The strain GXS16
showed maximum nitrogenase enzyme activity at pH 8 and 30 C, and nitrogenase
activity is less affected by different carbon sources. Further, strain GXS16 colonization
response was investigated through plant hormones analysis and RNAseq. The results
showed that the bacterial colonization gradually increased with time, and the H2O2 and
malondialdehyde (MDA) content significantly increased at 1 day after inoculation. There
were no substantial changes noticed in proline content, and the ethylene content was
detected initially, but it decreased with time. The abscisic acid (ABA) content showed
significant increases of 91.9, 43.9, and 18.7%, but conversely, the gibberellin (GA3)
content decreased by 12.9, 28.5, and 45.2% at 1, 3, and 5 days after inoculation,
respectively. The GXS16 inoculation significantly increased the activities of catalase
(CAT), superoxide dismutase (SOD), polyphenol oxidase (PPO), ascorbate peroxidase
(APX), and glutathione reductase (GR) at different timepoint. In contrast, the peroxisome
(POD) activity had no changes detected during the treatment. In the case of RNAseq
analysis, 2437, 6678, and 4568 differentially expressed genes (DEGs) were identified
from 1, 3, and 5 days inoculated root samples, and 601 DEGs were shared in all
samples. The number or the expression diversity of DEGs related to ethylene was much
higher than that of ABA or GA, which indicated the critical role of ethylene in regulating
the sugarcane roots response to GXS16 inoculation
A Humane Paradigm as the Conceptual Core of Education in the Age of Information Society
No full textThe article, based on a systematic analysis of the problems of national education
in the age of information society and digitalised education, reveals the significance
of the human paradigm, which is the conceptual core and the major
platform for the educational process under the regime of aggravation. The
convergence of education and information technology produces not only new
areas of knowledge, pedagogical tools and teaching methods but also large-scale
transformations in social practice. Like any social change, the digitalisation of
education has a variety of consequences – from positive to negative ones. It is
shown that the digitalisation of education, which meets great hopes not only in
Ukraine and Poland, can be productive only if an anthropocentric algorithm is
dealt with. Along with the huge and not much-studied possibilities of digitalisation
of education, it is proved that many problems and risks are associated
with the total introduction of the “digital” in the educational system. These are
social, psychological, health, organisational and methodological risks, and some
problems with the reduced quality of education. However, the ethics-related
risks are perhaps the most dangerous among them. As regards this, it is proved
that the humane paradigm, as a paradigm of the integrity of knowledge that
provides values and goals of education, is a guarantor of the harmonisation
in many processes related to translating information and knowledge into
a digital form. The humane paradigm is the basis of the genetic connection of knowledge, skills, digital literacy, moral imperatives, and life values, which in
a synergetic algorithm contribute to students’ effective development, systematic
thinking, and socialisation. The three most important blocks of educational
problems in the discourse on modern cyber-socialisation (transformation of
the worldview component of education, reconstruction of the content of education,
imbalance of educational and didactic processes) are outlined, and the
ways and mechanisms of solving them are suggested. Implementing integrated
strategies within the humane paradigm (which is the nourishing source of each
of these blocks) might result in the idea of the so-called “new humanism” in
education

Le cycle fantastique de La Montagne Morte de la Vie de Michel Bernanos – approche écocritique
No full textThe aim of the article is to analyse Michel Bernanos’ fantastic series The Other Side of the Mountain from an ecocritical perspective (among others, the literary text as L. Buell’s “green script”). The series first published in the sixties, constitutes an integral part of the well-known Angoisse collection edited by the publishing house Fleuve Noir, and its author is one of the most prominent figures of the "Fleuve Noir school of the fantastic". The innovative character of The Other Side of the Mountain consists of merging emblematic fantastic elements with protoecological ideas, which were, however, popularised by deep ecology only in the nineties
Projekty Hiszpańskiej Socjalistycznej Partii Robotniczej (PSOE) dotyczące zmiany Konstytucji Hiszpanii z 1978 r.
No full textThe main research objective of the study is to find an answer to the question: what are
the main assumptions of the political reform proposed by the Spanish Socialist Workers’
Party (Partido Socialista Obrero Español – PSOE) regarding the amendment of
the Spanish constitution of 1978? The study was carried out by implementation of the
method of qualitative data analysis and regarded selected legal acts and PSOE party
documents. The time frame of the study was set for the years 2004–2021. The initial
caesura is justified by the electoral victory of PSOE at 2004. The final turning point is
marked by the debates of the 40th PSOE Congress, held between October 15 and 17,
2021 in Valencia
Maszyna–podmiot–kultura. Debaty wokół postępu technicznego w Niemczech początku XX wieku
No full textThe main purpose of the article is to investigate the approach of the literature and film of the 1920s to technological progress, in particular, the process of mechanisation and its impact on social and individual life. The analyses of Bertolt Brecht’s poem (700 Intellektuelle beten einen Öltank an) and films of the German Expressionism (Student from Prague, Golem, Metropolis) aim to recapitulate the debates dealing with technological progress and place them within the horizon of the humanities; moreover, they aim to probe their approach to thought, dominated since the 18th century, distinguishing between the concepts of culture and civilization. By applying media theory of human extensions, the article tries to determine their potential of establishing the reality. In the central part of the analysis, the role of intellectuals and artists in the appliance of social life, the machine as a prosthesis and extension of human being, and the machine as a look-alike (Doppelgänger) are discussed
Kolej żelazna -nieodłączny element turystyki kulturowej i jej wizualne dokumentacje. Historia i współczesne perspektywy badawcze
No full textWynalazek kolei żelaznej znacząco wpłynął na kształt turystyki kulturowej. Kolej od momentu swego powstania stanowiła też interesujący temat dla fotografików i malarzy. Można zaobserwować pewną zbieżność tematyczną i kompozycyjną w obu tych obszarach. Współcześnie istnieje duże środowisko fotografików zainteresowanych tą tematyką. Dowodem na to są liczne blogi i strony internetowe zawierające stare i nowe zdjęcia związane z koleją i podróżą koleją. Zdjęcia te można podzielić według różnych kryteriów: tematycznego, chronologicznego, charakteru estetycznego (ukazujące piękno kolei bądź reportażowe). One posłużyły jako materiał wyjściowy do tych rozważań. Fotografia kolejowa stanowi także świetny obszar badawczy dla historyków, socjologów, antropologów i badaczy turystyki kulturowej. W ramach studiów nad kulturą wizualną dobrym sposobem analizy wydaje się być metoda proponowana przez Gillian Rose, opublikowana w publikacji zatytułowanej Visual Methodologies: An Introduction to Researching with Visual Materials. Koncentruje się ona przede wszystkim na osobie odbiorcy fotografii i elementach determinujących odbiór. W niniejszym artykule dokonano analizy tą metodą starych zdjęć z podróży Orient Expressem, zamieszczonych na internetowej stronie magazynu poświęconego fotografii
