“…Biflavonoids are always comprised of two units of flavonoids by a direct connection between the rings (A, B or C) of each flavonoid unit (He et al 2021). Biflavonoids were only found in the Dicranidae and Bryidae subclasses, mainly in Dicranales (Geiger et al 1997;Lindberg et al 1974;Markham 1988;Osterdahl & Lindberg 1977;Sala-Carvalho et al 2022;Waterman et al 2017;Zinsmeister et al 1996), Bartramiales (Basile et al 1999;Geiger et al 1997;Geiger & Bokel 1989;Kato-Noguchi 2016;L ópez-Sa ´ez 1996;Salm et al1993;Seeger et al 1991Seeger et al , 1993a, Bryales (Anhut et al 1989a,b;Geiger 1987;Geiger et al 1997Geiger et al , 1988Stein & Zinsmeister 1991), Aulacomniales (Geiger et al 1997;Hahn et al 1995), and Hypnales (Becker et al 1986;Brinkmeier et al 2000;Geiger et al 1997Geiger et al , 1988Li et al 2020;Seeger et al 1993bSeeger et al , 1992aSeeger et al , 1990Sievers et al 1992), but there were also reports of these compunds in Grimmiales (Geiger et al 1997), Hedwigiales (Zinsmeister et al 1996), and Rhizogoniales (Geiger & Seeger 2000;Zinsmeister et al 1996) (Fig. 9).…”

A chemistry overview of the beautiful miniature forest known as mosses

The bryophytes are the second largest group of land plants and are represented by three lineages: Marchantyophyta (liverworts), Anthocerotophyta (hornworts), and Bryophyta (mosses). They occupy a wide variety of habitats, from deserts to Antarctica, and exercise great ecological importance. These facts and their wide use in traditional medicine raise the question of what is known about moss chemistry. This paper gathered studies from the last 52 years about the compounds identified in mosses, aiming to address the following questions: Are mosses chemically under-studied? How many families, genera, and species of mosses have been chemically studied? Which continent and countries have been responsible for the majority of these studies? A literature search was performed in major scientific databases, using a combination of keywords. A total of 199 papers were compiled, of which 45% were published during the last decade. Only a small percentage of moss species has been studied, mostly from Europe and Asia. Dicranales and Hypnales are the most studied orders. In general, fatty acids and flavonoids are the most commonly reported classes of compounds. Biflavonoids and triflavonoids are detected mainly in derived clades of mosses, while coumarins are most reported for basal groups. Akthough only a small percentage of moss species has been chemically studied, most of these studies were published in the last decade—there has been a 135% increase in the number of reported compounds in the last 13 years. The emergence of new equipment, which can produce high-resolution spectra with small amounts of sample, combined with bioinformatics tools, has undoubtedly contributed to the increase of chemical investigation of mosses. Also, advances in the identification and phylogenetics of moss groups are contributing to a better understanding of them generally, which should lead also to increased study of moss chemistry.

“…Populations of C. purpureus exposed to continuous radiation may experience (i) partial chloroplast damage [ 50 , 55 , 88 ], (ii) decreased Rubisco carboxylation activity [ 50 , 56 ], (iii) decreased chlorophyll content [ 28 , 50 , 52 , 54 , 56 , 89 ], (iv) increased concentrations of carotenoids and anthocyanins [ 46 , 90 ], and (v) increased thickness of the cell wall [ 56 ]. Hence, the transition from shade-adapted to sun-adapted forms (or vice versa) seems to be related to the capability of C. purpureus to regenerate its chloroplast components [ 53 ], accelerate CO 2 assimilation [ 53 ], and protect itself from ambient UV [ 88 ].…”

Determining the physiological tolerance ranges of species is necessary to comprehend the limits of their responsiveness under strong abiotic pressures. For this purpose, the cosmopolitan moss Ceratodon purpureus (Hedw.) Brid. is a good model due to its wide geographical distribution throughout different biomes and habitats. In order to disentangle how this species copes with stresses such as extreme temperatures and high radiation, we designed a meta-analysis by including the main photosynthetic traits obtained by gas exchange measurements in three contrasting habitats from the Southern Hemisphere. Our findings highlight that traits such as respiration homeostasis, modulation of the photosynthetic efficiency, adjustment of the optimal temperature, and switching between shade- and sun-adapted forms, which are crucial in determining the responsiveness of this species. In fact, these ecophysiological traits are in concordance with the climatic particularities of each habitat. Furthermore, the photosynthetic trends found in our study point out how different Livingston Island (Maritime Antarctica) and Granite Harbour (Continental Antarctica) are for plant life, while the population from the Succulent Karoo Desert (South Africa) shares traits with both Antarctic regions. Altogether, the study highlights the high resilience of C. purpureus under abrupt climate changes and opens new perspectives about the wide spectrum of physiological responses of cryptogams to cope with climate change scenarios.

“…Currently, metabolomic, proteomics, and transcriptomics assays are well-established for P. patens [ 19 , 33 , 37 , 38 ], and similarly powerful tools are also being developed for C. purpureus [ 25 ]. Generally, the metabolome of C. purpureus appears to be diverse, with a number of biflavonoids, phospholipids, disaccharides, long-chain fatty acids, carotenoids, and antioxidants that change in abundance depending on the environmental conditions [ 26 ]. Some of the identified intracellular or cell-wall-bound biflavonoids display antioxidant and UV-protective activity [ 9 ].…”

“…Recent data point to intriguing differences between male and female strains of C. purpureus in the amount and composition of produced volatile organic compounds (VOCs) that can affect the behavior of soil microarthropods and attract them to aid in moss fertilization processes [ 23 , 24 ]. Overall, due to its small size, ease of laboratory cultivation, sequenced and annotated genome, and rapidly developing metabolomics resources, C. purpureus is currently becoming a model organism of choice for many types of plant research [ 22 , 25 , 26 ].…”

Identification and Analysis of Antimicrobial Activities from a Model Moss Ceratodon purpureus

The emergence of bacterial drug resistance is often viewed as the next great health crisis of our time. While more antimicrobial agents are urgently needed, very few new antibiotics are currently in the production pipeline. Here, we aim to identify and characterize novel antimicrobial natural products from a model dioicous moss, Ceratodon purpureus. We collected secreted moss exudate fractions from two C. purpureus strains, male R40 and female GG1. Exudates from the female C. purpureus strain GG1 did not exhibit inhibitory activity against any tested bacteria. However, exudates from the male moss strain R40 exhibited strong inhibitory properties against several species of Gram-positive bacteria, including Staphylococcus aureus and Enterococcus faecium, though they did not inhibit the growth of Gram-negative bacteria. Antibacterial activity levels in C. purpureus R40 exudates significantly increased over four weeks of moss cultivation in liquid culture. Size fractionation experiments indicated that the secreted bioactive compounds have a relatively low molecular weight of less than 1 kDa. Additionally, the R40 exudate compounds are thermostable and not sensitive to proteinase K treatment. Overall, our results suggest that the bioactive compounds present in C. purpureus R40 exudates can potentially add new options for treating infections caused by antibiotic-resistant Gram-positive bacteria.
