These genes mainly belong to gene families, such as the defense-related NBS-LRR (nucleotide-binding site leucine-rich repeat), lectin RLK (receptor-like kinase), and GST (glutathione transferase) gene families (Additional file 1: Fig. DNA of 55 individuals from 6 populations, which represent most of the known distribution of T. sinense trees, was extracted and sequenced using Illumina technology. Nucleotide diversity analysis of T. sinense showed high within-species genetic diversity (Additional file 1: Table S3) and its genetic diversity is higher than those reported for the relict species A. trichopoda [40] and Ginkgo biloba [69]. aralioides and A. coerulea, N. nucifera, and V. vinifera are 4: 2, 4:2, and 4:3 (Fig. 2d; Additional file 1: Fig. Rnammer: consistent and rapid annotation of ribosomal RNA genes. They were known in Sinhalese as "Kochhchi'. We obtained anchor genes from the inter-genomic synteny blocks with ratio of 1:2:4 in A. trichopoda, N. nucifera, and T. sinense. Contiguous and accurate de novo assembly of metazoan genomes with modest long read coverage. PubMed  CAS  S13 b–d. Tetracentron sinense Genome sequencing, assembly, resequencing and RNA-sequencing. Previous studies identified five or three refugia in China [31, 32]. Andrew Cosgrove was the primary editor of this article and managed its editorial process and peer review in collaboration with the rest of the editorial team. Somerville C.

Pigg KB, Dillhoff RM, DeVore ML, Wehr WC. Lagesen K, Hallin P, Rødland EA, Staerfeldt HH, Rognes T, Ussery DW. We estimated the divergence time of species using MCMCTree [37] and BEAST2 [38]. Li H. Minimap2: pairwise alignment for nucleotide sequences. Myriophyllum spicatum) or without any root system (e.g. 2020;37:2394–413. S8g, h), indicating one WGD in N. nucifera after the divergence from N. colorata and C. kanehirae. Whole-genome duplications (WGDs, polyploidization) have played a major role in the evolutionary history of the angiosperms. Durand NC, Robinson JT, Shamim MS, Machol I, Mesirov JP, Lander ES, et al. In the tangential section, we can clearly observe there are two types of tracheary elements. 2015;31:2032–4. Our light microscopy and SEM observations of slices of T. sinense wood and analyses of X-ray computed microtomography (microCT) (Fig. In subgroup MYB46 and MYB83, there are three T. sinense sequences (Tesin13G0114100, Tesin11G0137400, Tesin07G144300). Origin of angiosperms and the puzzle of the jurassic gap. 2019;5:461–70. Stem samples were boiled in water and sectioned on a sliding microtome, then cut into pieces about 1 cm in length and fixed overnight in 2.5% glutaraldehyde, followed by washing with 0.1 M PBS (pH 7.2) three times. Four homologous Tetracentron regions derived from two WGDs align with two distinct N. colorata regions. Cambridge: Cambridge University Press. The time of the more ancient bottleneck identified for two populations (CQ and SC) corresponds to the Naynayxungla glaciation (0.5–0.72 MYA, the most extensive glaciation in China [71]) and the time of the more ancient bottleneck of the other four population corresponds to the Guixiang glaciation (0.13–0.3 MYA [71]). 2010;8:77–80. Proc Natl Acad Sci 2010;107:22570–22575. CesAs in seed plants fell into six major clades, which were designated as six subfamilies: CesA1/10, CesA3, CesA6, CesA4, CesA7, and CesA8. Molecular data and ecological niche modelling reveal a highly dynamic evolutionary history of the East Asian Tertiary relict Cercidiphyllum (Cercidiphyllaceae). 2009;50:1950–64. The Biology of Aquatic Vascular Plants. Single clones harboring different vector combinations were transferred to SD/-THL medium containing 10, 20, 30, 40, 50, and 60 mM 3-AT and incubated at 30 °C for 0.5–8 h, and the color changes in the yeast cells were observed. Distributions of synonymous substitutions per synonymous site (Ks) were further analyzed to confirm the WGDs in Trochodendrales and other early diverging lineages of eudicots. In total, 87 R2R3-MYB genes were identified in the T. sinense genome. S12a), the two genes (AtLBD18 and AtLBD30) from A. thaliana formed one clade, suggesting that they originated from lineage-specific duplications. Then with this repeat library, RepeatMasker was used to identify repetitive elements in the genomic sequences. Genome Biol. Genome Biology The horizontal scale bar at the bottom (drift parameter) shows a tenfold average standard error of the entries in the sample covariance matrix. Subclassification and biochemical analysis of plant papain-like cysteine proteases displays subfamily-specific characteristics. DBLs are the main factor responsible for the lack of carbon fixation in aquatic plants. T. aralioides is a sister of T. sinense. d Luciferase activity assay showing that TsVND6.1 interacts with promoters of TsVND7.1 and TsVND7.2; TsLBD30a and TsLBD30b interact with the TsVND7.2 promoter; TsVND7.1 interacts with the TsCesA8 and TsXCPa promoters; and TsVND7.2 interacts with the TsMYB and TsCesA4 promoters. Angiosperm sequences of different subfamilies are shown in different colors and the gymnosperm sequences are shown in black. Zhong R, Richardson EA, Ye ZH. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. According to a CAFE analysis [39], five times as many gene families expanded in the lineage leading to all eudicots (551), as compared to core eudicots (110). We constructed a neighbor-joining (NJ) phylogenetic tree using MEGA7 [110] based on the whole-genome SNPs of the 55 individuals. 2010. Furthermore, the ALG24 MAD-box genes expanded rapidly in T. sinense (Additional file 1: Fig. Korneliussen TS, Albrechtsen A, Nielsen R. ANGSD: analysis of next generation sequencing data.
