Abstract Background Studying population genetic structure and gene flow of plant populations their influencing factors is particular significance in the field conservation biology, especially important for species such as rare endangered plants. Tetraena mongolica Maxim. (TM), belongs to Zygophyllaceae family, a with narrow distribution. However, last decade, due excessive logging, urban expansion, industrial tourism development, habitat fragmentation loss natural habitats have become major...

Genetic diversity, genetic structure, and gene flow in plant populations their influencing factors are important conservation biology. Cypripedium macranthos is one of the few wild orchids with high ornamental value northern China. However, over past decade, excessive collection, trading, tourism development, habitat fragmentation, deceptive pollination, seed germination difficulties have all caused a sharp decline number C. individuals its population. In order to propose scientific...

Based on our previous studies of 17 Prunus sibirica germplasms, one plus tree with high quality and quantity seed oils has emerged as novel potential source biodiesel. To better develop P. woody biodiesel, a concurrent exploration oil content, FA composition, biodiesel yield fuel properties well prediction model construction for was conducted developing seeds to determine the optimal harvest time producing high-quality Oil synthesis required supply carbon source, energy FA, but their...

Premise of the study: Microsatellite primers were developed to investigate population genetic structure in Lindera glauca (Lauraceae). Methods and Results: Twenty‐five microsatellite optimized for L. using Illumina's Solexa sequencing technology. These novel found be polymorphic nine wild populations with 81 total alleles confirmed genotyped via capillary gel electrophoresis. The number alleles, observed heterozygosity, expected heterozygosity each ranged from one four, 0.00 0.90, 0.79,...

is a crucial source of diverse industrial oil and medicines. The spicy aroma tender leaves caused by the presence abundant aromatic compounds. Here, we present its chromosome-level genome assembly comprising 12 pseudochromosomes (2,092.2 Mb; scaffold N50: 186.5 Mb), which was predicted to have 65,145 protein-coding genes. Comparative genomic analyses indicated two whole-genome duplication (WGD) events in Lauraceae family, contributing production numerous terpene synthase (

Lindera glauca (Lauraceae) is a tree of economic and ecological significance that reproduces sexually asexually via apomictic seeds. It widely distributed in the low-altitude montane forests East Asia. Despite potential implications mixed reproductive system terms genetic diversity, few studies have focused on this aspect. In study, structure wild populations L. was investigated analyses. Overall, 13 nuclear microsatellites (nSSRs) five chloroplast (cpSSRs) were used to genotype 300...

Abstract Background The Oriental Stork ( Ciconia boyciana ) breeds in southeastern Siberia and parts of northeast China, winters mainly southeast China. Although the autumn migration pattern Storks has been previously described, differences between spring travel speed relation to wind assistance were unknown. Methods Using GPS/GSM transmitters, we tracked full migrations 18 during 2015‒2018 compare patterns, combined satellite telemetry data with National Center for Environmental Prediction...

Because of rapid diversification and frequent interspecific gene flow within the genus inappropriate molecular markers used for phylogenetic studies, phylogeny evolution economically significant crop Vitis are poorly resolved understood, species delimitation remain disputable. In order to better understand relationships Vitis, phylogenomic analysis chloroplast genomes were performed based on extensive sampling scheme. Well tree clear divergence pattern obtained in present study. The results...

Background Elaiosomes are specialized fleshy and edible seed appendages dispersed by ants. Lipids the primary components of elaiosomes. Chelidonium majus is a well-known plant, seeds which Previous studies have identified presence fatty acids in its elaiosomes seeds. However, molecular mechanisms underlying acid biosynthesis remain unknown. Methods In order to gain comprehensive transcriptional profile C. , understand expression patterns genes associated with biosynthesis, four different...

Prunus (P.) humilis is a small woody shrub that has been widely planted in northern China due to its high nutritional value and resistance environmental abiotic stress. However, little information about the responses of photosynthetic performance anatomical structure P. saline–alkaline stress (SAS) under field conditions available. Here, we investigated behavior apparatus by measuring chlorophyll fluorescence parameters moderate (MS) severe (SS) analyzing their relationship leaf traits. The...

Coelogyne fimbriata is an important orchid species with high medicinal value. Its complete chloroplast genome 158,935 bp in length, which possesses the typical structure consising of a small single-copy region (SSC) 18,743 bp, two inverted repeats (IRs) 26,374 and large-single copy (LSC) 87,444 bp. The encodes 137 genes, including 91 protein-coding genes (PCGs), 38 tRNA 8 rRNA genes. And overall GC content 37.40%. In addition, our phylogenetic analysis based on cp revealed relationship...

Abstract Background Studying population genetic structure and gene flow of plant populations their influence factors is crucial in field conservation biology, especially rare endangered plants. Tetraena mongolica Maxim (TM), belong to Zygophyllaceae family, a with narrow distribution. Due excessive logging, urban expansion, industrial development the scenic spot last decades, has caused habitat fragments decline. Results In this study, diversity, TM were evaluated by reduced representation...

Abstract Salinity is regarded as the main environmental stress, which affects plant growth and physiological functions. miRNAs play crucial roles in plants salt stress response. Melilotus officinalis (L.) Pall. (MO) an excellent forage honey plant. In addition to its high medicinal values outstanding ecological effects, MO also has ability of tolerance. However, miRNA expression mechanism response still unclear. To reveal tolerance related predict their target genes MO, we extracted a small...
