Ionizing radiation can induce DNA damage and cell death by generating reactive oxygen species (ROS). The objective of this study was to investigate the radio-protective effect catalpol (a main bioactive component in traditional Chinese Rehmannia) on irradiated cells mice. We found that treating with (25-100 μg/ml) before irradiation could significantly inhibit ionizing (IR)-induced human lymphocyte AHH-1 apoptosis increase viability vitro. At same time our also showed mg/kg) reduced...

Tea one top three beverages world, improving quality tea a priority its research field. In this study, different concentrations (0, 10, 50, 100, 150, 200 mg·L−1) ZnO-NPs were sprayed on leaves investigate their effects volatile aroma...

Jasminum sambac is an excellent ornamental species that renowned worldwide for its pure white flowers and strong fragrance. However, intolerance to low temperatures limits cultivation range. Methyl jasmonate (MeJA), essential plant growth regulator, plays a significant role in assisting plants resist various stresses. Hence, this study was carried out decipher the capabilities of diverse concentrations MeJA helping J. cold stress by measuring different physiological indexes. A normal...

Melia azedarach Linn. is a deciduous tree of the genus in Meliaceae family that native to China. To study mechanism drought resistance and evaluate capacity each provenance, we selected eight provenances (Shandong Kenli, Jiangsu Pizhou, Hubei Shayang, Xuanwu, Jiangxi Xihu, Jurong, Guangdong Luogang, Henan Shihe) as research subjects set four levels stress treatment (CK: 75% field capacity, mild drought: 60% moderate 45% severe 30% capacity). The results showed growth seedling height ground...

Styrax tonkinensis, whose seeds are rich in unsaturated fatty acids (UFAs), is a high oil value tree species, and the seed has perfect biodiesel properties. Therefore, elucidation of effect 24-epibrassinolide (EBL) on acid (FA) concentration expression FA biosynthesis-related genes critical for deeply studying S. tonkinensis. In this study, we aimed to investigate changing trend composition identify candidate involved biosynthesis under EBL treatment using transcriptome sequencing GC-MS. The...

Tea has become one of the most popular drinks worldwide because its special taste and health benefits. ‘Yuhua’ tea is a famous specialty Nanjing, China, green produced from Camelia sinensis. It belongs to category top ten teas in China. The physical chemical properties soil are very important quality tea. However, at present, there few instances research on cultivation area. To provide theoretical basis for improving final by management measures, effects soil’s contents components (free...

Styrax japonicus is a small ornamental tree with medicinal values, although its flowering period short. To date, information about the morphological and physiological characteristics of petals during limited. In this study, we observed structure at full stage scanning electron microscope detected contents nutrients, minerals, endogenous hormones activities enzymes different stages. The results showed that content soluble sugar exhibited an ‘increase-decrease’ trend, whereas protein, nitrogen...

Leaf diseases such as Mosaic disease and Black Rot are among the most common affecting apple leaves, significantly reducing yield quality. Detecting leaf is crucial for prevention control of these conditions. In this paper, we propose incorporating rotated bounding boxes into deep learning-based detection, introducing ProbIoU loss function to better quantify difference between model predictions real results in practice. Specifically, integrated Plant Village dataset with an on-site leaves...

Liquidambar formosana Hance has a highly ornamental value as an important urban greening tree species with bright and beautiful leaf color. To gain insights into the physiological molecular mechanisms of L. color change, leaves three different clones were sampled every ten days from October 13, 2019, five times in total, which are S1, S2, S3, S4 S5. Transcriptome sequencing was performed at S1 S4. The chlorophyll content decreased significantly, while anthocyanins increased significantly...

Background: The conventional fertilization regime ignores the allometric characteristics of Quercus nuttallii seedlings, challenging them to meet nutritional needs at each growth stage. This study was conducted determine impact exponential on and nutrient status Q. container seedlings. Methods: Two regimes (average/exponential) were performed varied gradients (0, 300, 500, 700, 900 mg/seedling) N supply set for two regimes. Result: application promoted seedling height, root collar diameter,...

As global climate change worsens, trees will have difficulties adapting to abiotic pressures, particularly in the field, where environmental characteristics are difficult control. A prospective commercial and ornamental tree species, Styrax tonkinensis, has its seed oil output quality reduced as a result, which lowers economic benefits. This necessitates growers implement efficient strategies increase seeds of woody biofuel species’ tolerance stress. Numerous studies shown that ZnO...

Styrax is a gorgeous species combined with high medicinal and ornamental values, however, information about its floral scents limited. This study aimed to reveal the scent compounds dynamic changes in flowering process of japonicus, S. grandiflora calvescens. Static headspace solid-phase microextraction coupled gas chromatography-mass spectrometry was adopted present study. The results showed that 24, 22 volatile were at three stages, among which linalool, ocimene, α-pinene germacrene D...

Abstract Styrax japonicus is a gorgeous species with high medicinal and ornamental values. Floral scent an important feature of this species. However, the previous study on its floral limited. To demonstrate effects methyl jasmonate compounds in at different flowering stages, static headspace solid‐phase microextraction coupled gas chromatography‐mass spectrometry was adopted. The results showed that 22 volatile were identified control initial flowering, full end stage. Besides, relative...

As the germ of a highly productive oil tree species, Styrax tonkinensis seeds have great potential to produce biodiesel and they marvelous fatty acid (FA) composition. In order explore molecular regulatory mechanism FA biosynthesis in S. after methyl jasmonate (MJ) application, transcriptomic metabolomic techniques were adopted so as dissect genes that are related their expression levels, well discover major concentration The results revealed 200 μmol/L MJ (MJ200) increased crude fat (CF)...

Styrax tonkinensis is a white-flowered tree with considerable potential as feedstock source for biodiesel production from the oily seed contained within its nutlike drupes. Transcriptome changes during oil accumulation have been previously reported, but not concurrent in proteome.Using proteomic analysis of samples collected at 50, 70, 100 and 130 days after flowering (DAF), we identified 1472 differentially expressed proteins (DEPs). Based on their expression patterns, grouped DEPs into...
