Horsfieldia hainanensis is China’s second-class key protected wild plant with high scientific research, timber, and medicinal values. In this study, the SNP molecular marker technology was used to determine genetic diversity, structure, differentiation, relationship, its influencing factors of H. populations. It provided a basis for formulation protection strategy. The results showed that (1) diversity populations exhibited very low level (π = 0.0011). (2) overall differentiation relatively...

Sandy mice have a deletion mutation in the gene encoding dysbindin-1, Dtnbp1, with consequent reduction of protein heterozygotes and its loss homozygotes. The sandy mouse thus serves as an animal model dysbindin-1 function. As this is concentrated synaptic tissue affects transmitter release, it may affect neuronal processes that mediate behavior. To investigate neurobehavioral effects Dtnbp1 mutation, we studied littermate wild-type controls on C57BL/6J genetic background. three groups were...

Abstract Recently, dual‐atom alloy (DAA, also named diatomic alloy) catalysts with active metal dimers supported by a less host have attracted considerable interest owing to their distinctive geometric and electrical configurations. Despite developing many ways for synthesizing DAA catalysts, most contemporary methods depend on high‐temperature pyrolysis, costly apparatus, intricate procedures. This study presents, the first time, one‐step laser solid‐phase synthesis of (PtRu) 1 Co DAAs...

CLPTM1L is believed to be associated with lung cancer. However, there little information regarding its expression and function. Here using immunohistochemistry, we found that was markedly increased in cancer tissues relative normal tissues, especially adenocarcinoma. not stages, smoking status, lymph node metastasis, or T lymphocyte infiltration but differentiation stage. We enriched the mitochondrial compared plasma membrane protein extracts. CLPTM1L-EGFP transfection showed molecule...

Product initially increased sharply plateau about 12 15°C above the spouted bed at input 6.4 W/g. This remained almost constant thereafter. Uniform heating achieved as evidenced by uniform color temperature. Drying rates with increasing or level, But higher...

Abstract. This paper studies the direct impact of labour force ageing on productivity growth in 10 Canadian provinces over period 1981–2001, with an outlook to 2046. It shows that older workers are, average, less productive than younger and has a modest negative Canada. The increased since middle 1990s, will peak 2001–11, tail off afterwards. During period, Canada be reduced by 0.13 0.23 percentage points per year, Newfoundland being hit hardest. JEL classification: J21, O47

Kutze 'Pingyangtezao'] through a pot experiment. The results show that indicators photosynthesis were all suppressed with increasing stress, antioxidation protection systems destroyed. also discovered activities superoxide dismutase (SOD), peroxidase (POD) catalase (CAT) decreased, while content proline (Pro)...

Vatica guangxiensis X. L. Mo (Dipterocaceae) is a valuable timber tree species endemic to China and typical plant with extremely small populations (PSESP). To understand the pattern variations in genetic diversity of V. during natural regeneration, large-scale genome-wide SNPs were developed using genotyping by sequencing (GBS) assess population structure infer demographic history. The observed heterozygosity (HO), expected (HE), nucleotide (π) 0.1810, 0.2128, 0.2178, respectively,...

Understanding genetic diversity is a core issue in conservation genetics. However, previous evaluations of narrowly distributed species have rarely used closely related widespread as reference. Furthermore, identifying natural hybridization signals between and widely sympatric great importance for the development programs.

Abstract Whether ex situ populations constructed in the limited nursery resources of botanical gardens can preserve enough genetic diversity endangered plants wild remains uncertain. Here, a case study was conducted with Camellia tunghinensis , which is one species lowest natural distribution area sect. Chrysantha (golden camellia) family Theaceae. We investigated and population structure 229 samples from using genotyping by sequencing (GBS). Core germplasm these samples. The results showed...

Camellia nitidissima, a rare and endangered shrub is narrowly distributed in South China North Vietnam occurring forest understory. Their light tolerance mechanism unclear. We measured photosynthesis related parameters on 2-years-old cuttings growing at 10, 30, 50 100% sunlight. Our research question was: At what level are C. nitidissima responding most favorably, the eco-physiological basis for their response to light? hypothesized that as understory growth of would respond favorably low...

The main active components of the Camellia sect.Chrysantha flowers were analyzed and antioxidant activity total flavonoids compared.The results showed that among 10 species Sect.Chrysantha plants, C. nitidissima had highest contents TFC (0.848 g/100 g) TSC (6.824 g), insularis content TPOC (4.3 g).The TPC (17.188 CTC (101.026mg/100 achrysantha was significantly higher than other 9 species.C. pubipetala GAC (1.586 amino acids tunghinensis acid all species.Comprehensive evaluation flowers, it...

Sophora japonica L. (Faboideae, Leguminosae) is an important traditional Chinese herb with a long history of cultivation. Its flower buds and fruits contain abundant flavonoids, therefore, the plants are cultivated for industrial extraction rutin. Here, we determined complete nucleotide sequence mitochondrial genome S.

The genus Ormosia comprises approximately 130 species, which are found in tropical regions all over the world. taxonomy and evolutionary history still ambiguous due to lack of a solid phylogeny at species level. Due fast advancement high-throughput sequencing technology, it is now possible retrieve full chloroplast (cp) genome sequence, providing molecular basis for phylogenetic analysis. Five were used this work, their whole cp genomes sequenced. One circular, quadripartite-structured...

Golden Camellia species are highly specific to certain soil environments. Most only native calcareous soils in karst regions, except for a few that grow acidic soils. Our aim is elucidate the adaptation mechanisms of calcareous-soil golden (CSC) and acidic-soil (ASC) habitat through plant–soil nutrient characteristics their relationships. We investigated 30 indices plants. Compared with ASC, CSC had more fertile soil, while plant tissues exhibited stronger Ca, P, Mn weaker K storage, which...

Karst tiankengs in China are globally significant locations for studying ecological environments and plant diversity. However, there few reports on how the unique geographical environment of affects genetic diversity structure. This study used Hyper-seq gene sequencing technology to develop large-scale genomic SNPs Manglietia aromatica, both within outside tiankengs. Its aim was investigate impact structure M. aromatica population. The analysis results indicate that populations tiankeng (π =...

Abstract The homeodomain-leucine zipper (HD-Zip) gene family plays a pivotal role in plant development and stress responses. Nevertheless, comprehensive characterization of the HD-Zip kiwifruit has been lacking. In this study, we have systematically identified 70 genes Actinidia chinensis (Ac) genome 55 eriantha (Ae) genome. These categorized into four subfamilies (HD-Zip I, II, III, IV) through rigorous phylogenetic analysis. Analysis synteny patterns selection pressures provided insights...

The complete mitochondrial DNA (mtDNA) cytochrome b gene (1140 bp) was sequenced in Herzenstein macrocephalus and Gymnocypris namensis 13 other species sub‐species ( n = 22), representing four closely related genera the subfamily Schizothoracinae. Conflicting taxonomies of H. G. have been proposed because character instability among individuals. Parsimony, maximum likelihood Bayesian methods produced phylogenetic trees with same topology resolved several distinctive clades. Previous...
