Advances in Research with Bryophytes

Topic Information

Dear Colleagues, 

Bryophytes (mosses, liverworts, and hornworts) are the closest living relatives to the earliest land plants. During their evolution from water to land, they have adapted and developed mechanisms to sustain the dry and harsh conditions on land. As a result, bryophytes can be found in almost every land ecosystem, occurring in cold and wet arctic environments and even in hot and dry deserts. For thousands of years, bryophytes have been used by humans as part of ethno-medicinal remedies in traditional medicine, as padding material to stabilise wooden joints in clay buildings, or as filtering material to clean polluted water in latrines and fountains. These traditional uses have inspired research to explore their potential for use in biotechnology and bioengineering from various perspectives. Bryophytes are currently considered in a wide range of applications ranging from using biologically active products in medicine, agroecology and biology, as pharmaceutic flavouring agents, as part of bioreactors, biofuels, in understanding ecosystem responses to climate change, in rewilding ecosystems, in paludicultures, as bioindicators, in the filtering of pollutants, or in gardening and floristics.

To this end, a large diversity of biologically active compounds and specialized genes have been discovered in bryophytes that are absent from vascular plants. In the last decades, bryophytes such as Physcomitriella/Physcomitrium patens and Marchantia spp. have become model species in the production of biotechnologically relevant compounds that show antimicrobial, antibacterial, antifungal, antiviral and even anticancer effects. The rapidly increasing level of information on genetics has enabled functional and comparative genomic approaches and the construction of metabolic pathways promoting molecular biotechnological approaches.

All types of high-quality submissions, such as original research papers, opinions, and reviews are welcome.

Prior to the advent of molecular work, the observable variation in vegetative reproduction has been used to classify Lejeunea into subgenera and sections. Thereby, the ability of developing caducous leaves was regarded as major factor. A reexamination of several Lejeunea specimens revealed that L. cocoes with caducous leaves shows considerable morphological differences with non-caducous leaved plants of L. cocoes. Phylogenetic analyses based on a three-marker dataset (rbcL, trnLF and the nuclear ribosomal ITS region) indicated two independent and robust lineages of the morpho-species L. cocoes. We consider both clades as two distinct species and therefore describe the new species, L. malaysiana for L. cocoes morpho-species with caducous leaves. Lejeunea malaysiana is characterized by its caducous leaves with ribbon-like and plantlet regenerants, strongly reduced leaf lobules, distant and deeply bilobed underleaves, long-keeled obovoid perianth, and autoicy and ranges from tropical Asia to the Pacific region.

In the course of a worldwide revision of the genus Syntrichia, we identified problems in the circumscription of some species of the genus as well as among some allied genera grouped in the tribe Syntricheae. This is the case for the two propagulose Syntrichia amphidiacea and S. gemmascens, closely related to Streptopogon. We analyzed phylogenetic relationships between these species, based on nuclear (ITS) and two plastid (trnL-F and trnG) markers and morphological features. Species delimitation using molecular data was consistent with our preliminary morphological inference. Phylogenetic analyses were performed using maximum likelihood and Bayesian inference methods. Our results placed Syntrichia amphidiacea in the Streptopogon clade. Syntrichia gemmascens is also included in Streptopogon in spite of the discrepancy of the ITS and plastid relationships, which could be evidence of an exchange of genetic material between species in various lineages in the Pottioideae. Streptopogon is maintained as a separate genus on the basis of morphology characters, and we consider the differentiation of laminal papillae and the presence of a stem central strand as new characters in the genus. We accept Sagenotortula as distinct genus sister to Syntrichia. We consider the lack of costal dorsal epidermis and the differentiation of a crescent-shaped costal dorsal stereid band as distinctive generic characters in Syntrichia. Additionally, we include Syntrichia percarnosa as a new synonym for S. breviseta. Three names are lectotypified. Full article

Mosses are critical components of tropical forest ecosystems and have multiple essential ecological functions. The drying and rehydrating and often hot environments in tropical regions present some of the greatest challenges for their photosynthetic activities. There is limited knowledge available on the physiological responses to the changing environments such as temperature and water pattern changes for terrestrial mosses. We examined the seasonal dynamics of photochemical performance of PS II through the measuring of chlorophyll fluorescence of 12 terrestrial mosses in situ from five different elevations by Photosynthesis Yield Analyzer MINI-PAM-II, along with the seasonal changes of climatic factors (air temperature, dew point, relative humidity and rainfall), which were collected by local weather stations and self-deployed mini weather stations. The results showed a great seasonality during observing periods, which, mainly the changes of rainfall and relative humidity pattern, presented significant impacts on the photochemical performance of PS II of terrestrial mosses. All these tested moss species developed a suitable regulated and non-regulated strategy to avoid the detrimental effect of abiotic stresses. We found that only Hypnum plumaeforme, Pterobryopsis crassicaulis and Pogonatum inflexum were well adapted to the changes of habitat temperature and water patterns, even though they still experienced a lower CO₂ assimilation efficiency in the drier months. The other nine species were susceptible to seasonality, especially during the months of lower rainfall and relative humidity when moss species were under physiologically reduced PS II efficiency. Anomobryum julaceum, Pogonatum neesii, Sematophyllum subhumile, Pseudotaxiphyllum pohliaecarpum and Leucobryum boninense, and especially Brachythecium buchananii, were sensitive to the changes of water patterns, which enable them as ideal ecological indicators of photosynthetic acclimation to stressed environments as a result of climate change.
