“…Several thalloid liverwort genera, and many moss genera, have species with considerable drought tolerance, with examples in both plant groups of individuals withstanding continuous desiccation for more than 20 years (Breuil-Sée, 1993;Stark et al, 2017). As the plants of liverwort genera such as Riccia and Targionia dry out, the sides of the thallus roll over the dorsal surface so that it is covered by the darkly pigmented ventral scales and rhizoids [see Figure 4 and Reeb et al (2018) for examples]. This forms a "capsule" that can recover and renew growth even after extended periods without additional water.…”

The flavonoid pathway is one of the best characterized specialized metabolite pathways of plants. In angiosperms, the flavonoids have varied roles in assisting with tolerance to abiotic stress and are also key for signaling to pollinators and seed dispersal agents. The pathway is thought to be specific to land plants and to have arisen during the period of land colonization around 550-470 million years ago. In this review we consider current knowledge of the flavonoid pathway in the bryophytes, consisting of the liverworts, hornworts, and mosses. The pathway is less characterized for bryophytes than angiosperms, and the first genetic and molecular studies on bryophytes are finding both commonalities and significant differences in flavonoid biosynthesis and pathway regulation between angiosperms and bryophytes. This includes biosynthetic pathway branches specific to each plant group and the apparent complete absence of flavonoids from the hornworts.

“…R2R3-MYB activation of flavonoid production in the same species during abiotic stress has also been delineated (Albert et al, 2018). Some species of other thalloid liverworts roll their thalli over the dorsal surface when dried out, so that dark pigmented ventral side is left exposed (Reeb et al, 2018;Davies et al, 2020), whereas some desiccation-tolerant leafy liverworts also tend to be dark pigmented (Vitt et al, 2014). The adaptive value of these pigmentations of assumed auronidin type is still subject for debate, light screening, ROS scavenging, strengthening of the cell wall and biotic stress defense are mentioned as possible functions (Davies et al, 2020).…”

Natural products from plants have served mankind in a wide range of applications, such as medicines, perfumes, or flavoring agents. For this reason, synthesis, regulation and function of plant-derived chemicals, as well as the evolution of metabolic diversity, has attracted researchers all around the world. In particular, vascular plants have been subject to such analyses due to prevalent characteristics such as appearance, fragrance, and ecological settings. In contrast, bryophytes, constituting the second largest group of plants in terms of species number, have been mostly overlooked in this regard, potentially due to their seemingly tiny, simple and obscure nature. However, the identification of highly interesting chemicals from bryophytes with potential for biotechnological exploitation is changing this perception. Bryophytes offer a high degree of biochemical complexity, as a consequence of their ecological and genetic diversification, which enable them to prosper in various, often very harsh habitats. The number of bioactive compounds isolated from bryophytes is growing rapidly. The rapidly increasing wealth of bryophyte genetics opens doors to functional and comparative genomics approaches, including disentangling of the biosynthesis of potentially interesting chemicals, mining for novel gene families and tracing the evolutionary history of metabolic pathways. Throughout the last decades, the moss Physcomitrella (Physcomitrium patens) has moved from being a model plant together with Marchantia polymorpha in fundamental biology into an attractive host for the production of biotechnologically relevant compounds such as biopharmaceuticals. In the future, bryophytes like the moss P. patens might also be attractive candidates for the production of novel bryophytederived chemicals of commercial interest. This review provides a comprehensive overview of natural product research in bryophytes from different perspectives together with biotechnological advances throughout the last decade.

“…The checklist of the liverworts of this area proposed here, is based on the records of this field trip and of herbarium-housed specimens collected during earlier explorations and recent data from the literature (Reeb et al 2018;Reeb and Gradstein 2020;Pócs 2011Pócs , 2015Pócs , 2020a2021;Sass-Gyarmati and Reeb 2021;Sass-Gyarmati et al 2022).…”

This updated checklist of Marchantiophyta (liverworts) of Andasibé (Périnet) region, Madagascar was compiled from the literature, from herbarium specimens and recent collections. A total of 222 species including 9 infraspecific taxa, from 62 genera are recorded. Five species: Cheilolejeunea ngongensis Malombe et Pócs, Cheilolejeunea unciloba (Lindenb.) Malombe, Heteroscyphus grandistipus (Steph.) Schiffn., Lejeunea angulifolia Mitt. and Kymatocalyx africanus Vána et Wigginton are newly reported for Madagascar. Detailed informations on species occurrences are provided as a basis for subsequent research on species distributions and conservation.
