Abstract Salix matsudana is a deciduous, rapidly growing willow species commonly cultivated in China, which can tolerate drought, salt, and heavy metal stress conditions. Selection of suitable reference genes for quantitative real-time PCR important normalizing the expression key associated with various stresses. To validate genes, we selected 11 candidate (five traditional housekeeping six novel genes) analyzed their stability samples, including different tissues under abiotic treatments....

Apricot (Prunus armeniaca L.) fruits are highly perishable and prone to quality deterioration during storage transportation. To investigate the effects of LED white light treatment on postharvest ripening using metabolomics, transcriptomics, ATAC-Seq analysis. Fruits were exposed 5 μmol m-2 s-1 for 12 hours followed by darkness at 20 °C daily days. The treatments physiological nutritional evaluated. These data combined with transcriptomic, metabolomic, from taken Day 8 provide insight into...

The coefficient variation clone repeatability for growth traits Cd concentration large. accumulation 107 QHQ reached 1.9 1.7 mg, respectively, followed by QHB, Ti, 69, Pa, which 1.3 mg. Most intra-specific (69, QH1, SL4, T3, ZL46) had low concentrations small biomass,...

Summary Most cashmere goats are found in northern China and Mongolia. They regarded as precious resources for their production of high quality natural fibre the textile industry. It was first time that genetic diversity population structure nine Chinese populations has been assessed using 14 ISAG/FAO microsatellite markers. In addition, two Iranian one West African goat were genotyped comparison. Results indicated rich, but less than those populations. All pairwise F ST values between...

We determined the genetic diversity and evolutionary relationships among 26 Chinese indigenous horse breeds two introduced by genotyping these animals for 27 microsatellite loci. The come from 12 different provinces. Two were Mongolia B Horse Thoroughbred UK. A total of 330 alleles detected, expected heterozygosity ranged 0.719 (Elenchuns) to 0.780 (Dali). mean number 6.74 (Hequ) 8.81 (Debao). Although there abundant variations found, differentiation was low between horses, which displayed...

Abstract Integrating multiple facets of biodiversity to describe spatial and temporal distribution patterns is one way revealing the mechanisms driving community assembly. We assessed species, functional, phylogenetic composition structure passerine bird communities along an elevational gradient both in wintering breeding seasons Ailao Mountains, southwest China, order identify dominant ecological processes structuring how these change with elevation season. Our research confirms that...

Background. Chinese fir [ Cunninghamia lanceolata (Lamb.) Hook.] is one of the most important native tree species for timber production in southern China. An understanding overall fast growing stage, stem growth stage and senescence cambium transcriptome variation lacking. We used sequencing to identify repertoire genes expressed during development xylem tissue fir, aiming delineate molecular mechanisms wood formation. Results. carried out at three different cultivation ages (7Y, 15Y 21Y)...

Abstract Cd is one of the potential toxic elements (PTEs) exerting great threats on environment and living organisms arising extensive attentions worldwide. Sedum alfredii Hance, a hyperaccumulator, importance in studying mechanisms hyperaccumulation has potentials for phytoremediation. ATP-binding cassette sub-family C (ABCC) belongs to ABC transporter family, which deemed closely associate with multiple physiological processes including cellular homeostasis, metal detoxification, transport...

The animal mitochondrial DNA (mtDNA) length polymorphism and heteroplasmy are accepted to be universal. Here we report the lack of structural variation but presence as well in mtDNA control region an endangered avian species – Crested Ibis (Nipponia nippon). complete was directly sequenced while distribution pattern inheritance variations were examined using both direct sequencing genotyping PCR fragments from captive birds with pedigrees, wild a historical specimen. Our results demonstrated...

The soundscape of different habitats can be discriminated by multiple acoustic indices as they have previously been related to vegetation characteristics. However, the relationship between and topography still needs thoroughly evaluated, well variance in at spatial scales within same research system. Networks forest dynamics plots constructed under protocol provide an ideal platform for addressing above issue. Our study investigated indices, vegetation, topographic characteristics two...

Frugivory and seed dispersal are key processes that shape both plant animal communities, they important in the maintenance regeneration of forest ecosystems while threatened by environmental changes. This study investigated frugivores factors affecting visitation fruit consumption evergreen tree Baccaurea ramiflora (Lour.) Chinese (Xishuangbanna) Thai (Mo Singto) tropical plots. The two plots differ their mammal faunas, with more large species (Asian elephant, white-handed gibbon, bears)...

Sex Identification of monomorphic birds, especially endangered avian species, is essential for ecological study and biodiversity conservation. In this study, two popular primer sets 2550F/2718R P2/P8, which were designed to amplify different fragments chromodomain-helicase-DNA binding protein 1 (CHD1) genes mapped on both Z W chromosomes in used identify the first time sex individuals species crested ibis (Nipponia nippon) a large number samples. An improved set 2467F/2530R was re-designed...

Abstract Evaluating the relative importance of deterministic and stochastic processes underlying taxonomic functional beta diversity is crucial in community ecology, because it can reveal dominant assembly. However, studies bird communities remain rare limited spatial extents. In this study, we described patterns 32 passerine assemblages Yunnan Province, China. We constructed null models based on observed species used multiple regressions distance matrices to evaluate contributions...

Bottle gourd (Lagenaria siceraria (Molina) Standl) is a widely distributed Cucurbitaceae species, but gaps and low-quality assemblies have limited its genomic study. To address this, we assembled nearly complete, high-quality genome of the bottle (Pugua) using PacBio HiFi sequencing Hi-C correction. The genome, being 298.67 Mb long with ContigN50 28.55 Mb, was identified to possess 11 chromosomes, centromeres, 18 telomeres, 24 439 predicted protein-coding genes; notably, gap-free...

• We investigated how passerine species add to the functional trait space and underlying ecological process maintain co-occurrence as richness increase from high low latitude. Environmental filtering is generally important for bird assemblages this regional pool. Simultaneously, spacing of within tend constrained by negative biotic interactions across latitudinal gradient. Both climate factor vegetation structure were indicators environmental filtering, with potentially acting a key...

Abstract Long‐term vegetation plots represent one of the largest types research investments in ecology, but efforts to interrelate data on plants with that animals are constrained because disturbance produced by human observers. Recent advances automated identification animal sounds large datasets autonomously collected audio recordings hold potential describe plant–animal interactions, such as between frugivorous birds and fruiting trees, without disturbance. We deployed an array nine...
