In this study, using the replacement series experiments designed by de Wit, the effects of different shading treatments on the morphological structure, physiological characteristics, and competitiveness of the invasive plant\u0000 A. tauschii\u0000 were comparatively analyzed with the aim of providing knowledge for the ecological control of this weed in wheat fields. The results showed that in terms of morphological characteristics, shading caused an increase in plant height, leaf area, and specific leaf area (SLA); and a decrease in the root-to-crown ratio (R/C) of both\u0000 A. tauschii\u0000 and wheat plants. With regard to physiological characteristics, both\u0000 A. tauschii\u0000 and wheat plants adapted to the low-light environment by increasing the chlorophyll content, with an increase of chlorophyll\u0000 b\u0000 in particular. It could be concluded from the changes in superoxide dismutase (SOD) activity and thiobarbituric acid reactive substances (TBARS) content that the low-intensity shading treatment significantly improved the stress resistance of\u0000 A. tauschii\u0000 , thus ensuring the continuation of its normal photosynthesis. In addition, the plasticity index average value of eight morphological indicators of\u0000 A. tauschii\u0000 (e.g., plant height and leaf area) was 0.18, which was greater than that of wheat (0.17). Similarly, the plasticity index average value of four physiological indicators of\u0000 A. tauschii\u0000 (e.g., chlorophyll content and SOD activity) was 0.46, which was also higher than that of wheat (0.37). Finally, the competitive balance (CB) value of\u0000 A. tauschii\u0000 showed that its competitiveness under low light conditions was still greater than wheat, but gradually diminished with increasing shading rate. In short,\u0000 A. tauschii\u0000 displays a certain adaptability to low light environments, but shading treatment may also significantly reduce its competitive inhibition of wheat.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47970041","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}

This review summarizes the activity of research groups from the University of Wrocław completed over the last 3 decades which tends to focus on potatoes and flax likely as a result of their centuries-old tradition of cultivation, processing, and use in Poland. The aims of these studies were various and included the creation of pathogen-resistant plants, increased antioxidant production, improved flax fiber quality, and improved oil properties. New plant breeds initially produced using genetic engineering technology provide an excellent basis for improving our understanding of the genes involved in potato and flax productivity and the quality of their products. These results have been published in many papers and have given rise to new methods for plant breeding and product prototypes which have been patented. However, none of the prototypes have been commercialized because of their GMO origins. In addition, later development of a novel, epigenetic method has led to the creation of more diverse products based on the newly obtained variety of flax called Silesia. These developments have facilitated the production of a range of new raw materials from these epigenetically modified plants. These include a modified oil for improved nutrition and regeneration of skin cells, seed- cake extracts that act as anti-infection agents, improved fiber production for use as bandages for chronic wounds, improved fibers for application as bio composite materials for the development of biodegradable packaging materials and scaffolds for tissue engineering, and micronized fiber for drug delivery. These modifications mean that flax has become a more useful and valuable source of a wide range of raw materials applicable in industry, allowing for the application of these materials in zero waste applications.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46141050","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, in distant crosses, many prezygotic and postzygotic barriers are encountered that prevent free, uncontrolled gene flow between species. Therefore, various experimental methods exploiting tissue culture, such as in vitro fertilization, embryo rescue, and protoplast fusion, have been developed to raise hybrids that cannot be obtained naturally through conventional approaches.\u0000 Professor Maciej Zenkteler of the Adam Mickiewicz University in Poznań pioneered the use of tissue culture in Poland to overcome barriers to sexual crossing. In the mid-1960s, he employed in vitro pollination in which pollen grains were directly applied onto the surface of exposed ovules as the primary method to bypass prezygotic barriers and in vitro culture of isolated ovules and developing embryos (embryo rescue) to overcome post-zygotic barriers. These approaches proved effective for species possessing numerous ovules and large placentas, such as representatives of the families Caryophyllaceae, Solanaceae, and Brassicaceae. Soon thereafter, these methods were extended to other Polish institutes and universities and applied for crop improvement, such as for the production of intergeneric hybrids between\u0000 Salix\u0000 and\u0000 Populus\u0000 species, resynthesis and broadening of the genetic variability of oilseed rape (\u0000 Brassica napus\u0000 L.), and the generation of new interspecific hybrids of\u0000 Allium\u0000 .\u0000 In the late 1970s, Professor Zenkteler was the first to undertake protoplast fusion. At that time, it appeared that no incompatibility could exist at the fusion level and that somatic hybridization would supersede the possibilities offered by sexual hybridization; however, the reality turned out to be slightly harsh. Nonetheless, successful regeneration of different interspecific hybrids of potato, tomato, or gentians has been achieved by Polish research groups thus far.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41346078","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}

Yet another pattern, manifested in the rippled surface of some tree trunks, has remained basically undescribed. This work is the first attempt to provide information on its morphology, dynamics, and relation to the tangential waviness. Developmental analysis of the annual ring widths on the transverse surface of the stem showed that crests and throughs forming a ripple pattern result from a highly controlled proliferation of cambial cells. These cells’ activity regularly oscillates in time and space between an increased and a reduced state at approximately 10-year intervals, independently of the environmental cues considered in dendrochronological studies. This rhythm leads to the development of radial waviness and is a major factor affecting wood ring width. Radial waviness is dynamic; it propagates along the stem axis and is often synchronized with tangential waviness in a nonrandom manner. Possible causes of radial pattern emergence based on auxin waves, the role of other phytohormones, and recent discoveries of MADS-box genes that regulate cambial cell proliferation are discussed.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47747186","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}

Since the first publications on SE in 1958, this regeneration process has been applied to the in vitro propagation of many plant species and has led to the development of some specific model systems. SE has been used to expand our understanding of the cytomorphological, physiological, biochemical, and genetic processes that govern the earliest developmental events in the life of plants. This paper summarizes the achievements of Polish research groups working on SE systems established for several plants (gentians, the tree fern\u0000 Cyathea delgadii\u0000 Sternb., and conifers) and three model species (\u0000 Arabidopsis thaliana\u0000 ,\u0000 Medicago\u0000 sativa\u0000 , and\u0000 M. truncatula\u0000 ). SE systems have used a broad spectrum of experimental approaches involving genomic tools (transcriptomics, proteomics, and chromatin analyses), physiological methods which focus on phytohormones, and cytological techniques. Studies on the experimental models of\u0000 A. thaliana\u0000 and\u0000 Medicago\u0000 spp. have resulted in the identification of new genetic and epigenetic elements of the complex regulatory network controlling embryogenic induction in plant somatic cells. The protocol developed for ferns has provided a unique and simple system for cytological analysis of early SE events that occur in a single cell of initial explants. Gentian embryogenic suspension cultures have successfully been used in broad biotechnological applications, including plant transformation, protoplast isolation, culture, and fusion. Systems described for coniferous species effectively produced many vigorous somatic seedlings and cost-efficient storage of genotypes during clonal field-testing.
