Abstract:
The group of pleurocarpous mosses comprises approximately 5000 species, which corresponds to about half of all mosses. The pleurocarpous mosses (i.e. “the Core Pleurocarps”) form a monophylum, which consists typically of perennial mosses with creeping stems and abundant lateral branches. In pleurocarpous mosses the archegonium and thus also sporophyte development is restricted to the apices of short, specialized lateral branches, in contrast to most other mosses, where archegonia and sporophytes develop terminally on the main axis (acrocarpous) or on major branches (cladocarpous). Traditionally, pleurocarpous mosses have been divided into three orders based mainly on their sporophytic characters. Brotherus described the Neckeraceae in 1925 and placed it into the Leucodontales, later the family has alternatively been divided into two or three separate families: the Thamnobryaceae, the Neckeraceae and the Leptodontaceae. These families have been placed even in different orders (Neckeraceae and Leptodontaceae among the leucodontalean mosses and Thamnobryaceae among hypnalean mosses) according to their peristome structure and the grade of peristome reduction. A growing amount of evidence indicates that a grouping based on sporophytic characters is artificial and based on convergent evolution. According to the latest phylogenetic studies of pleurocarpous mosses, based on molecular data, the Neckeraceae belong to the order Hypnales and share a sister group relationship with the Lembophyllaceae. In the most recent comprehensive classification 28 genera were included in the Neckeraceae family. This classification was based on both morphological and molecular data, but done with limited taxon sampling that did not cover all species of the family. Some previous studies based on molecular data have challenged the family concept of the Neckeraceae, indicating the need for a revision of the family. Here the family concept of the Neckeraceae is revisited, the closest relatives of the family are resolved and its position within pleurocarpous mosses is shown. In addition, new insights into the morphological evolution of the family are provided. Previous phylogenetic studies indicated that branch lengths among pleurocarpous mosses are usually extremely short. Therefore we chose to use mainly non-coding DNA sequences from rapidly evolving DNA regions. The phylogenetic reconstructions are based on extensive sequence data from all genomes: plastid trnS-trnF and rpl16, nuclear ITS1 & 2 and mitochondrial nad5. Both parsimony (PAUP and PRAP2) and Bayesian statistics (MrBayes) were employed for phylogenetic reconstructions. In order to use the information provided by length mutations indels were included in the analyses as binary data using a simple indel coding approach. No severe conflicts appeared between the different methods used, but the indel coding affected the support values of the inferred topologies. Therefore, all support values resulting from different methods are shown along the phylogenetic trees. The morphological features are studied and synapomorphies for each clade formed in the phylogenetic analyses are interpreted. A new delimitation of the family makes it necessary to reconsider the relevance of the morphological description and the morphological features characteristic of the family need to be reconsidered. Due to new groupings, some changes in the morphological circumscriptions of the genera are necessary, resulting in two new genera and several new combinations. Chapter 1 gives a broad overview of the relationships of the pleurocarpous mosses and shows the need for changes in the definition of genera, families and the corresponding nomenclature in this group. Chapter 2 is a population genetic study on the genus Thamnobryum. The main aim of this chapter is to test the species concept in Thamnobryum that are endemic to strictly restricted regions showing only minor differences in the morphological features in comparison to some more common species. In Chapter 3 the monophyly of the Neckeraceae is tested. In addition, in this chapter the ancestral character states of some morphological characters within the Neckeraceae are reconstructed. Chapters 4 and 5 resolve the genus composition and the relationships within the family in more detail. The results of this thesis show that the Neckeraceae need re-circumscription; this includes changes in the genus composition. The Lembophyllaceae is confirmed to be the sister group of the Neckeraceae. In addition to the new phylogeny, the potential evolution of several characters as a result of environmental selection pressures is analyzed. From the ancestral state reconstructions made (using BayesTraits) for both the habitat and a selection of morphological characters, character state distributions and habitat shift appear congruent, peristome reduction being a good example. However, some character states do not correlate with the habitat, suggesting very complex evolutionary patterns underlying these morphological characters. Many widely distributed genera that are composed of several species and seem to be morphologically coherent (Echinodium, Homalia, Thamnobryum, partly Neckera), are shown in this thesis to be polyphyletic. They are replaced by smaller, geographically more restricted genera that at least in some cases (e.g. Thamnomalia, Homalia s.str., Neckera s.str.) seem to form morphologically heterogeneous genera. In other words, morphology can be misleading in the family Neckeraceae even at the genus level and convergent evolution in both morphological and sequence level characters are common within the family. Special habitat conditions have been shown to result in similar morphological structures also in several other moss groups. This kind of convergent evolution occurs in aquatic mosses, and seems to have occurred among the neckeraceous species Thamnobryum alopecurum and its allies. However, similar morphological structure in similar aquatic habitats can also be due to true phylogenetic relationships as is the case within the Neckeraceae for Handeliobryum sikkimense and Hydrocryphae wardii, or the members of Touwia. The geographical grouping seems to be more strongly correlated with the phylogenetic grouping than thought before.

Abstract:
Entosthodon Schwägr. (Funariaceae) is a genus of soil-inhabiting, annual to biennial mosses occurring worldwide in temperate to tropical-montane climates. Although a number of regional revisions and treatments exist for the genus, in many parts of the world, it remains poorly known. This is perhaps especially true in Africa, where the identities of most species names are obscure. Furthermore, recent work on the Funariaceae suggests that the sporophytes, long used as the main basis for classification and identification in the group, exhibit high levels of homoplasy and that Entosthodon is paraphyletic as currently circumscribed. I further test the monophyly of Entosthodon, and its relationships to other members of the Funarioideae, through phylogenetic analysis of DNA sequences from four chloroplast regions. These analyses included 45 Entosthodon species (ca. 50 % of those currently recognised), as well as an additional 22 species comprising representatives of all genera of the subfamily (except the rare, monotypic genera Cygnicollum, Clavitheca, Nanomitrella and Brachymeniopsis and the recently described monotypic Afoninia). Bayesian analyses of these data strongly contradict the monophyly of Entosthodon, and it is instead resolved as paraphyletic to a large clade comprising mostly members of Physcomitrium and Physcomitrella. Within this grade, five well supported lineages are resolved - the first comprises 3 species of Entosthodon and is sister to the second lineage, the monotypic Physcomitrellopsis. The third is sister to the afore mentioned i clades and comprises 11 species of Entosthodon within which the monotypic genus Funariella is embedded. The fourth lineage comprises 7 species of Entosthodon and is sister to a clade within which a Physcomitrium-Physcomitrella group is sister to the fifth lineage - a large clade comprising 24 species of Entosthodon. Entosthodon hungaricus is shown to belong in the Physcomitrium clade instead, consistent with its rostrate operculum. Based on the phylogeny, a new classification of Entosthodon sensu lato is proposed. The genus is split into 4 genera (Amphoritheca, Fifeobryum gen nov., Funariella and Entosthodon sens. str.) and the monophyletic Physcomitrellopsis is also maintained. Because of a lack of diagnostic morphological taxonomic characters this new classification is based largely on the molecular circumscription of clades. Nonetheless, particular character combinations do largely characterise most of these genera, albeit that frequent reversals render particular character states non-diagnostic. A revision of these five genera for Africa results in the recognition of twentysix species in total: three in Amphoritheca, 12 in Entosthodon, one in Physcomitrellopsis, one in Fifeobryum, and nine in Funariella. Six of these species, 4 in Entosthodon and 2 in Funariella, are newly described based on specimens from East and southern Africa. A key to the sub-Saharan species is provided, and each is fully described, mapped and illustrated.

Abstract:
Les strigolactones (SL) sont une nouvelle classe de phytohormones, retrouvées chez toutes les plantes terrestres. Chez les plantes vasculaires, les SL ont un rôle hormonal prédominant dans la régulation de l’architecture aérienne, mais aussi une fonction de signal symbiotique, favorisant ainsi la captation d’eau et de nutriments du sol par les plantes. Ces deux fonctions ont conduit à l’hypothèse selon laquelle les SL ont pu être essentielles dans les processus de colonisation du milieu terrestre par les plantes il y a 450 millions d’années. L’étude de la biosynthèse et de la signalisation des SL chez la bryophyte Physcomitrium patens (P. patens, non-vasculaire), par comparaison avec ce qui est connu chez les plantes vasculaires, permet de questionner l’évolution des voies cellulaires associées aux SL chez les plantes terrestres. Chez les plantes vasculaires, les voies de biosynthèse et de perception des SL sont assez bien décrites. La voie de signalisation des SL commence par la perception de la molécule par le récepteur D14 dans le cytosol, qui la clive et reste associé à une partie de la SL. Ce complexe interagit dans le noyau avec deux partenaires : la protéine à boîte F MAX2, capable de recruter un complexe d’ubiquitination, et certaines protéines SMXL. Ces protéines agissent comme des répresseurs de la réponse aux SL et vont être ubiquitinées sous l’action du complexe recruté par MAX2, puis rapidement dégradées par le protéasome. Chez P. patens, la plupart des gènes de biosynthèse et de signalisation des SL sont retrouvés, parfois en nombres différents comparés aux plantes vasculaires. Seules des approches de génétique inverse permettent de définir précisément leur fonction. La précédente caractérisation du mutant de biosynthèse Ppccd8 chez P. patens a montré que les SL sont synthétisées via une voie similaire à celle des plantes vasculaires. En outre, la fonction des SL dans la régulation de l’architecture est conservée chez P. patens. Au contraire, en accord avec la découverte précédente que l’unique homologue de MAX2 chez P. patens n’est pas impliqué dans la signalisation des SL, les résultats ici présentés indiquent que la signalisation des SL n’est que partiellement conservée entre P. patens et les plantes vasculaires. En effet, seuls 2 homologues PpKAI2L de D14, sur les 13 possédés par P. patens, sont impliqués dans la perception des SL, d’après l’étude de mutants perte-de-fonction et les analyses de biochimie. Par ailleurs, les protéines PpKAI2L sont phylogénétiquement plus proches d’une autre protéine appelée KAI2 que de D14. Or KAI2 ne perçoit pas les SL chez les plantes vasculaires. De plus, la caractérisation des mutants perte-de-fonction Ppsmxl, obtenus par l’utilisation de la technologie CRISPR, et les analyses de liaison génétique avec PpMAX2 et PpCCD8 montrent que les quatre protéines PpSMXL ne jouent pas un rôle majeur dans la réponse aux SL. Cependant, les protéines PpSMXL les plus proches phylogénétiquement des SMXL ancestrales apparaissent comme des régulateurs importants de la croissance, ce qui pourrait constituer le rôle ancestral des protéines SMXL, en accord avec des études phylogénétiques récentes. Cette régulation de la croissance constituerait la réponse à un autre signal endogène, plus ancestral que les SL, le KL (ligand de KAI2). La transduction du signal KL serait conservée au moins chez les plantes terrestres et impliquerait chez P. patens certaines protéines PpKAI2L et les protéines PpMAX2 et PpSMXL. L’identité moléculaire du KL n’a pas encore été élucidée. N’étant pas conservée chez P. patens, la signalisation des SL résulte possiblement d’une innovation spécifique de la lignée des plantes vasculaires. Ainsi, la voie de réponse aux SL présente chez la mousse résulterait d’une évolution convergente vers la perception des SL. Il reste donc à élucider comment le signal SL est transduit chez P. patens, en aval de sa perception par certaines protéines PpKAI2L<br>Strigolactones (SL) make up a novel class of phytohormones that are found across the whole land plant lineage. In vascular plants, the main hormonal role of SL is the repression of shoot axillary branching. However, SL are also a major symbiotic signal, granting the plant increased access to the nutrients and water contained in the rhizosphere. These two functions of SL led to the hypothesis that these molecules have been instrumental at the time of land colonization by plants, approximately 450 million years ago. Studying SL biosynthesis and signaling in the bryophyte Physcomitrium patens (P. patens, a non-vascular plant), and comparing these processes with the available knowledge in vascular plants, enables to investigate the evolution of SL cellular pathways in land plants. As a matter of facts, SL biosynthesis and signaling pathways are quite extensively described in vascular plants. Notably, SL signaling starts in the cytosol where the SL molecule binds to the D14 receptor. D14 cleaves the SL and stays covalently linked to a part of the SL. Under this conformation, D14 can then interact with two partners in the nucleus: the MAX2 F-box protein and SMXL proteins. SMXL proteins act as repressors of the SL response, as their interaction with D14 and MAX2 will trigger their ubiquitination and subsequent proteasomal degradation. Most SL biosynthesis and signaling genes have homologs in P. patens genome, sometimes in different numbers. Nevertheless, only reverse genetics approaches can clearly establish these homologs function. Previous characterization of P. patens SL deficient mutant Ppccd8 revealed that SL biosynthesis is broadly conserved between mosses and vascular plants. Furthermore, SL play a similar role in the regulation of plant architecture in P. patens as demonstrated in vascular plants. On the other hand, results presented herein show that SL signaling is only partly conserved between P. patens and vascular plants, supporting the prior observation that the sole MAX2 homolog in P. patens is not needed for SL response. Indeed, only 2 out of the 13 P. patens D14 homologs (PpKAI2L genes) are involved in SL perception according to the characterization of Ppkai2l CRISPR knock-out mutants and to biochemistry analyses. Moreover, instead of D14, PpKAI2L proteins are closer to the KAI2 protein, which is not involved in SL perception in vascular plants. In addition, the phenotype of CRISPR knock-out mutants for the PpSMXL genes, together with genetic linkage analysis of PpSMXL with PpMAX2 and PpCCD8, show that none of the 4 PpSMXL proteins play a major role in SL response. However, the two PpSMXL homologs that are closer to the ancestral land plants SMXL seem to be important regulators of growth, which as per recent phylogenetic studies could be the ancestral role of the SMXL family. This effect on growth would actually be the main response to the ancestral KL (KAI2-ligand) signal, an endogenous signal different from SL. Transduction of the KL signal would hence be conserved across land plants and would be achieved in P. patens via some PpKAI2L proteins, together with the PpMAX2 and at least two PpSMXL proteins. To date, the identity of the KL molecule(s) remains under debate. As SL signaling is not conserved in P. patens, it appears that the known SL signaling pathway results from a vascular plants specific innovation. Likewise, SL response in P. patens would be the product of a convergent evolution. Therefore, the question as to how P. patens transduces the SL signal, downstream of perception by specific PpKAI2L proteins, remains open

Abstract:
Bryophytes, which include about 24,000 taxa and consist of mosses (Bryopsida), liverworts (Hepaticopsida), and hornworts (Anthocerotopsida), are the largest group of secondary terrestrial plants after angiosperms. Indigenous communities globally use bryophytes for various medicinal purposes, including antimicrobial, antipyretic, dermatological, hepatic, cardiovascular, and wound-healing properties. Found in diverse habitats, excluding oceans, bryophytes are significant sources of bioactive compounds, particularly secondary metabolites such as steroids, alkaloids, phenols, coumarins, flavonoids, and tannins. These compounds demonstrate various therapeutic activities, including antimicrobial, antioxidant, anti-inflammatory, antidiabetic, and anti-cancer effects. This study aims to provide a comprehensive review of the ethnomedicinal uses of bryophytes and the therapeutic applications of their secondary metabolites.

Abstract:
Abstract The Bryopsida, or mosses, are a diverse assemblage of species that form the second largest group of green land plants (Vitt 1982). In general, mosses are poikilohydric and drought tolerant (Proctor 1972; Levitt 1980). As a result of these two characteristics, species can maintain active photosynthesis only when water is available. The ability of this group of plants to tolerate frequent dry periods by coming to thermodynamic equilibrium with their surroundings has enabled them to occupy highly stressed habitats. The abundance and species richness of mosses in tropical montane rain forests; on montane cliff faces and canyons; in boreal forests; in subarctic, boreal, and temperate peatlands; and in arctic meadows, indicates that this group of plants can exist under water- and nutrient-stressed conditions, and also be a dominant component of the ecosystem. Recent studies of tropical montane rain forests (Coxson and Vogel 1989), boreal forests (Oechel and Lawrence 1985), peatlands (Bayley et al. 1987), and arctic meadows (Vitt and Pakarinen 1977) have all suggested that the moss component can have a great influence on the nutrient dynamics and water retention of the ecosystem. However, it is only in peatlands in which continuous records of past species occurrences are found.

Abstract:
The article discusses new data obtained in the study of the functions of a conservative peptide of cabbage plants, which is encoded by the microRNA156a. Comparative analysis of the nucleotide sequences of the promoter regions of these genes allowed us to identify a highly conserved 42-residue block located before the starting point of pri-miR156a transcription at a distance of 210-260 base pairs. It was found that promoter fragments containing a highly con-served block have a significantly higher ability to bind miPEP156a in vitro. We carried out mutagenesis of a highly conserved promoter block in its central part, which includes a tetramer of TG dinucleotides. It has been shown that the introduction of mutations into the promoter tetramer of TG dinucleotides significantly reduces the affinity of the promoter DNA to miPEP156a. The miPEPs revealed in plants have been found only in dicotyledons. The question of how miPEPs are distributed in other plant taxa is very important for understanding the evo-lutionary origin of such micropeptides. As an initial approach, we searched for taxonomically conservative miPEPs in mosses, since microRNAs have been studied in a great detail in the case of Physcomitrium patens moss. For two genes in the region preceding the Ppt-pre-miR160a sequence, rather short open reading frames were found that encoded peptides having a clear similarity of amino acid sequences in the central region. Importantly, such highly con-served peptide block homologous to that encoded by Ppt-miPEP160a gene was detected in short proteins encoded in pri-miR160a in almost 20 Bryopsida mosses.
