The temporal and spatial heterogeneity of soil water content affects the isotopic composition of bulk soil water and xylem water. However, there is a lack of systematic assessment of the impact of soil water conditions on the widely reported bulk soil-xylem water isotopic offset. For this purpose,...

Objective: To understand the relationship between water and carbon metabolism and growth and fruiting of branches at different positions in the crown of Hippophae rhamnoides for providing a certain theoretical basis for the formulation of cultivation technical measures for Hippophae rhamnoides tree ...

Two bacterial strains, designated as 1-4-3^T and 1-4-4, were isolated from a mangrove sediment cultured with coastal seawater. The cells were Gram-stain-negative, motile, short, rod-shaped bacteria with flagella. Growth occurred at 4-37°C, pH 7.0-9.0, and 0-7% NaCl. The predominant fatty acids of...

The four-subfamily subdivision of Rosaceae has been recently replaced by a three-subfamily scheme. The re-circumscribed Rosoideae lacks a solid and well-resolved phylogeny on which a classification can be based. In this study, we sampled 56 genera presumably belonging to Rosoideae and 10 genera...

Root growth potential (RGP) is a popular physiological indicator used to evaluate seedling vigor. However, the time scale used in the RGP test is the order of days, which leads to poor performance of the RGP method. We propose an optical interference method, called statistical interferometry, to...

This study aimed to explore how carbon limitation affects the carbon allocation and hydraulic characteristics of trees. It was conducted on three-year-old Robinia pseudoacacia Linn. seedlings by three-time artificial defoliation. Biomass allocation, leaf morphology, nonstructural carbohydrate (NSC) ...

Homeobox (HB) genes play critical roles in the regulation of plant morphogenesis, growth and development. Here, we identified a total of 156 PtrHB genes from the Populus trichocarpa genome. According to the topologies and taxonomy of the phylogenetic tree constructed by Arabidopsis thaliana HB...

Galactinol synthase (GolS; EC 2.4.1.123) is a member of the glycosyltransferase eight family that catalyzes the first step in the biosynthesis pathway of the raffinose family of oligosaccharides (RFOs). The accumulation of RFOs in response to abiotic stress indicates a role for RFOs in stress...

Chemical investigation of the fruits of Phyllanthus emblica led to the isolation of one new aryltetralin-type lignan (1), along with twelve known polyphenols (2-13). Their structures were determined via extensive analyses of spectroscopic data and comparison with the reported literature values....

The alteration of surface microstructures and chemical composition in cuticle of papaya fruit in response to chilling stress were comparatively studied between cultivars of 'Risheng' and 'Suihuang' after harvest. Fruit surface was covered by fissured wax layers in both cultivars. The presence of...
