Abstract The taxonomic classification of Picea meyeri and P. mongolica has long been controversial. To investigate the genetic relatedness, evolutionary history, population history dynamics these species, genotyping-by-sequencing (GBS) technology was utilized to acquire whole-genome single nucleotide polymorphism (SNP) markers, which were subsequently used assess structure, dynamics, adaptive differentiation. Phylogenetic structural analyses at genomic level indicated that although ancestor...
Platycladus orientalis , a common horticultural tree species, has an extremely long life span and forms graceful canopy. Its branches, leaves, cones have been used in traditional Chinese medicine. However, difficulty rooting is the main limiting factor for conservation of germplasm resources. This study shows that rates root numbers cuttings were significantly reduced ancient P. donors compared to 5-year-old donors. The contents differentially accumulated metabolites (DAMs) phenylpropanoid...
To evaluate the effects of donor ages on growth and stress resistance 6-year-old seedlings propagated from 5-, 2000-, 3000-year-old Platycladus orientalis donors with grafting, cutting, seed sowing, indicators physiological transcriptomic analyses were performed in winter. Results showed that basal stem diameters plant heights three propagation methods decreased age donors, sown thickest tallest. The contents soluble sugar, chlorophyll, free fatty acid apical leaves negatively correlated...
Abstract Background Phytohormones are the key factors regulating vascular development in plants, and they also involved tension wood (TW) formation. Although theory of hormone distribution TW formation is widely supported, effects endogenous hormones on have not yet been assessed. In this study, was induced Catalpa bungei by artificial bending. The phytohormone content TW, opposite (OW) normal (NW) determined using liquid chromatography-mass spectrometry (LC-MS), transcriptome sequencing...

Heavy metal pollution is a global environmental problem, and Quercus variabilis has stronger tolerance to Cd stress than do other species. We aimed explore the physiological response molecular mechanisms of Q. stress. In this study, antioxidant enzyme activities leaves were determined, while photosynthetic parameters measured using Handy PEA, ion fluxes DEGs in roots investigated noninvasive microtest technology (NMT) RNA sequencing techniques, respectively. at different concentrations for...
Picea koraiensis is major silvicultural and timber species in northeast China, its distribution area an important transition zone for genus spruce migration. The degree of intraspecific differentiation P. high, but population structure mechanisms are not clear. In this study, 523,761 single nucleotide polymorphisms (SNPs) were identified 113 individuals from 9 populations by genotyping-by-sequencing (GBS). Population genomic analysis showed that was divided into three geoclimatic regions:...
The effects of tree age on the growth cutting seedlings propagated from ancient trees have been an important issue in plant breeding and cultivation. In order to understand seedling stress resistance stability, phenotypic measurements, physiological assays, high-throughput transcriptome sequencing were performed sown 5-year-old donors 5-, 300-, 700-year-old Platycladus orientalis donors. this study, was significantly slower; soluble sugar chlorophyll contents gradually decreased with...
Stem cuttings of the endangered ancient Platycladus orientalis are a valuable genetic resource for cryopreservation and propagation, but their extremely hard adventitious root (AR) formation poses challenge regeneration. In this study, we investigated causes decreased AR during initial stem (S1), callus expansion (S2), (S3) stages in from 5-, 100-, 700-year-old P. trees, identified potential solutions to enhance formation. Proteomic analysis revealed an up-regulation flavonoid...
Picea belongs to the Pinaceae family and is a famous commercial tree species because of its straight trunk excellent timber traits. Recently, omics have been widely used for fundamental mechanism studies on plants. To improve accessibility phenotypic data facilitate further studies, we compiled sequences 2 chloroplast genomes (Picea crassifolia asperata) 32 complete sets, including 20 transcriptomes, 4 proteomes, degradomes 6 microRNAs from P. crassifolia, asperata, balfouriana abies tissues...
Genome-wide single nucleotide polymorphism (SNP) markers were obtained by genotyping-by-sequencing (GBS) technology to study the genetic relationships, population structure, gene flow and selective sweeps during species differentiation of Picea wilsonii, P. neoveitchii likiangensis from a genome-wide perspective. We used jezoensis pungens as outgroups, three evolutionary branches obtained: was located on one branch, two wilsonii populations grouped onto second third branch. The relationship...
