Pterocarpus santalinus is considered among the finest luxury woods in world and has potential commercial medicinal value. Due to its rich hue high price, often been substituted mislabeled with other of lower economic To maintain order timber market interests consumers, it necessary establish a fast reliable method for species identification. In this study, wood samples nine commonly used counterfeiting were analyzed by visible light/near-infrared (Vis/NIR) hyperspectral imaging (HSI). The...

Anthocyanins are responsible for the intensity of color in plants; however, systematic mechanisms underlying differences fruit Ailanthus altissima remain unknown. Therefore, this study aims to analyze transcriptomes white and red A. by screening validating key genes involved flavonoid anthocyanin biosynthesis. Samples were collected 30, 45, 60 days after flowering, their pigment sugar content determined. The was significantly higher than fruits. Transcriptome analysis also performed on...

Abstract Background Exploring the genetic mechanisms underlying speciation is a hot topic in modern genetics and evolutionary studies. Distortion of marker transmission ratio frequently ascribed to selection against alleles that cause hybrid incompatibility. The natural introgression between P. massoniana hwangshanensis their distribution ranges lead emergence two species as desirable organisms study for speciation. Results Using seeds sampled from trees at different elevations, we...

Near infrared hyperspectral imaging (NIR-HSI) spectroscopy can be a rapid, precise, low-cost and non-destructive way for wood identification. In this study, samples of five Guiboutia species were analyzed by means NIR-HSI. Partial least squares discriminant analysis (PLS-DA) support vector machine (SVM) used after different data treatment in order to improve the performance models. Transverse, radial, tangential section separately select best sample The results obtained demonstrated that...

The composition and content of sugar play a pivotal role in goji berry (Lycium barbarum L.) fruits, determining fruit quality. Long-term exposure to elevated CO2 (eCO2) was frequently demonstrated reduce secondary metabolites. In order understand the regulatory mechanisms improve quality changing climate, it is essential characterize metabolism genes that respond eCO2. objectives this study were clone full-length cDNA three genes—LBGAE UDP-glucuronate 4-epimerase), LBGALA...

Plants in coastal areas often face the combined stress of salt and flooding, which can cause severe damage. The impact multiple stresses on plant growth survival is greater than that individual stresses. However, molecular responses hybrid willow (Salix matsudana × alba) to combination flooding have not been well understood. In this study, we conducted a comparative transcriptome analysis investigate mechanism underlying tolerance salt-flooding. Seedings were, respectively, treated with 200...

In order to learn dormancy mechanism of Taxtts chinensis var. mairei seed, effects stratification and hormone treatments on physiological biochemical indexes the seeds after stratifying for eight months were researched. The content amylase activity soluble sugar gradually increased at first stratification, then maximum end after-ripening period. With seed relieving, some endosperm was used or consumed by respiration that led their decreased. Seed protein accumulated beginning initial raw...

Abstract Ailanthus altissima is a deciduous tree native to China and introduced other parts of the world as an ornamental plant. It exhibits resistance both abiotic biotic stress factors has various pharmacological effects strong allelopathy, generating significant research interests. However, genome sequence this species not been reported, limiting its development. The purpose study was determine size characteristics A. conduct genomic survey. Next-generation sequencing K-mer analysis were...

In order to understand the drought resistance and salt tolerance of maple leaves Fontanesia fortunei Carr. this study, seeds were treated with different concentrations PEG NaCl solutions investigate their effects on growth physiology. The results demonstrated that control group had highest germination rate. a significant impact root length but minimal influence plant height, mild stress promoting growth. Increasing associated higher MDA content, peaking at 10% concentration, while SOD...

Root growth potential (RGP) is a popular physiological indicator used to evaluate seedling vigor. However, the time scale in RGP test order of days, which leads poor performance method. We propose an optical interference method, called statistical interferometry, measure minute root elongation at sub-nanometer scale, can decrease measuring RGP. The this method also 104 times less than that Because we length continuously, compute rate (RER), variety per second. Continuous monitoring help...
