“…In addition, the promoter region of MpFTPSL2 was strongly active in OB cells while the suppression of several MpFTPSLs genes in transgenic Marchantia plants resulted in low accumulation of sesquiterpenes compared to wild type thalli (Takizawa et al, 2021). MTPSL proteins are also involved in sesquiterpene biosynthesis and diversity in the leafy liverworts Mylia taylorii (Yan et al, 2021) and Radula lindenbergiana (Fan et al, 2021). This specific group of MTPSL genes, likely acquired through horizontal gene transfer from bacteria and fungi, might explain the singular chemical compounds found in bryophytes, and more specifically in liverworts (Chen et al, 2018).…”

Liverworts are known for their large chemical diversity. Much of this diversity is synthesized and enclosed within the oil bodies (OB), a synapomorphy of the lineage. OB contain the biosynthetic enzymes to produce and store large quantities of sesquiterpenoids and other compounds while limiting their cytotoxicity. Recently, there were important biochemical and molecular discoveries related to OB formation, diversity and biochemistry that allows the comparison with other secretory structures of land plants in an evo-devo perspective. In this review, we address and discuss the most recent advances in OB origin, development and function to understand the importance of these organelles in liverwort physiology and adaptation to the changing environment. Our mapping of OB-types and chemical compounds to the current liverwort phylogeny suggests that OB were already present in the most recent common ancestor of liverworts, supporting OB evolved as the first secretory structure in land plants. Still, we require a better sampling to define the macroevolutionary pattern governing the ancestral type of OB. We conclude that current efforts in finding molecular mechanisms responsible for this morphological and chemical diversity of secretory structures will help understand the evolution of each major group of land plants, and open new avenues in biochemical research of bioactive compounds for both bryophytes and vascular plants.

“…As located in the cold-arid regions of northern China, the Daihai lake and the Wuliangsuhai Lake are facing similar problems with other lakes from the cold-arid regions globally, such as water shortage and area shrinkage (Tziotis et al 2011;Bai et al 2014;Cui et al 2021;Yan et al 2021;Oyewusi et al 2021). Aiming at the specific environmental factors and microbial communities of these two lakes, the species and structure of DOM were analyzed to find the causes of eutrophication, providing a theoretical basis for solving the environmental problems of lakes.…”

During freezing periods, nutrients (carbon and organic matter, etc.) are enriched in the water and sediment of lakes in cold-arid regions, leading to potential algal bloom outbreaks and other health risks to the ecosystem. Particularly, dissolved organic matter (DOM) is a critical component of the nutrients and plays an important role in the global carbon cycle. However, the mechanisms of DOM transfer between ice and water remain unclear. This study analyzed the influence of microbial community on DOM composition using 16 s RNA, 3DEEM, and FT-ICR MS in Daihai Lake and Wuliangsuhai Lake in the Yellow River Basin, China. According to the spectral analysis, the content of endogenous organic matter, such as humus, accounted for 40% of the total DOM in water, while the content of tryptophan and tyrosine accounted for 80% of the total DOM in ice. The results of mass spectrometry showed that lignin was the main component, and the content of organic matter in the ice was less than that in the water. Molecular structures of seven DOM coexisting in the lake ice and water were elucidated with adapted Kendrick-analogous network visualization, which clearly illustrates that long-chain DOM molecules are derived from small molecules, while other heteroatoms are complexed with the side groups. The positive correlations between CHO, CHNO, CHOS, CHOS and Actinomyces indicate that DOM actively interacted with the microbial community. 44% of CHO compounds have the same molecular formula in water, the content of CHOS in the water of the two lakes was closed to 7% higher than that in the ice. Meanwhile, DOM dynamically migrate between ice and water via interstitial water because of the solubility changes under microbial transformation, which has been proved by the decrease in the contents of the humus and tryptophan-like substances in the ice from the bottom to the surface and lower contents of carbohydrate and unsaturated aromatic hydrocarbon in the water than the ice. This study helps to predict the composition and structure of DOM during the migration in lakes and provides a scientific basis for environmental remediation with high concentration of carbon.
