Application of plant DNA metabarcoding of lake sediments for monitoring vegetation compositions on the Tibetan Plateau

引用

Science China Earth sciences 2024年第11期67卷 3594-3609页

作者： Kai WU Kai LI Weihan JIA Kathleen R.STOOF-LEICHSENRING Ulrike HERZSCHUH Jian NI Mengna LIAO Fang TIAN College of life sciences Zhejiang Normal University polar Terrestrial Environmental Systems Research Group Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research Institute of Environmental Science and Geography University of Potsdam Institute of Biochemistry and Biology University of Potsdam College of Resource Environment and Tourism Capital Normal University

Benefiting from the rapid development of environmental DNA(eDNA) technologies, sedimentary DNA(sedDNA)emerges as a promising tool for monitoring plant compositions in remote regions. The Tibetan Plateau(TP), renowned for its harsh environment and numerous ponds and lakes, presents a potentially demanding region for the application of sedDNA on vegetation investigations. Here, we used the g and h universal primers for the P6 loop region of the chloroplast trn L(UAA)intron to amplify plant DNA in surface sediments from 59 ponds and small lakes on the southwestern TP. The applicability and limitations of using plant DNA metabarcoding for modern vegetation monitoring and palaeo-vegetation reconstructions have been assessed by comparing sedDNA, pollen, and vegetation survey data. Our results showed that plant DNA metabarcoding recorded 186 terrestrial taxa, of which 30.1% can be identified at the species level. The plant sedDNA approach can effectively disclose the dominant plant taxa(including Asteraceae, Cyperaceae and Poaceae) and significant vegetation assemblages in the vicinity of the investigated sites. The number of taxa and taxonomic resolution of plant sedDNA exceeded that of pollen analysis(75 taxa detected, 5.3% can be identified at species level). Unlike pollen that retains a broad spectrum of regional plant signals(including Pinus and Artemisia), plant sedDNA mirrors very local plants, underscoring its utility in local vegetation monitoring and reconstructions. To conclude, plant DNA metabarcoding of(small) lake sediments warrant increased attention in the future for local vegetation monitoring and reconstructions on the TP.

Dear Editor,Protein histidine methylation has been found to be a widespread post-translational modification(PTM)in mammalian cells and represents more than 13%of all protein methylation events in the human methylome(Ning et al.,2016;Kapell and Jakobsson,2021).Recently,we and other groups independently identified METTL9 as the first broad-specificity histidine N1 methyltransferase in mammals(Davydova et al.,2021;Lv et al.,2021).METTL9 methylates a variety of substrates with a common x-His-x-His motif(His is for histidine;the second x is preferably small amino acids:A/C/G/S)and catalyzes methyl transfer to the last histidine.

Rice breeding for low methane and high yields

Rice is the staple food for more than half of the world’s population,and the demand for rice is expected to increase by 28%by 2050(Jiang et al.,2017).However,rice production is one of the largest anthropogenic sources of the potent greenhouse gas methane(CH4),accounting for 22%of total agricultural CH4 emissions(Qian et al.,2023).Therefore,to achieve sustainable intensification of rice cultivation,it is necessary to increase yields while reducing CH4 *** management techniques to reduce CH4 emissions while maintaining high yields have been studied extensively over the past few decades,but crop breeding to reduce CH4 emissions without compromising yields has received less attention(Kwon et al.,2023).
