Nitrogen (N) partitioning within a leaf affects leaf photosynthesis and adaptation to environmental fluctuations. However, how plant sex influences leaf N allocation and its tradeoffs in acclimation to drought, excess salt and their combination remains unknown. Here, leaf N allocation between the...

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,...

The increased frequency and intensity of drought pose great threats to the survival of trees, especially in dioecious tree species with sexual differences in mortality and biased sex ratios. The sex-specific mechanisms underlying stem xylem anatomy and function and carbon metabolism in drought...

Water is the main limiting factor for survival and growth for desert plants, and plants can alleviate water deficits under drought by adjusting water potential (Ψ). However, the water potential adjustment capacity and water-sensitivity at the tissue level among shrub species remains unclear. The...

Qiongyin No.8 jackfruit is a superior variety bred from the native offspring in Thailand. Due to its high yield, good quality and early maturity, it was introduced into Hainan in 2012. In 2014, it began to blossom and bear fruit, and the buds were grafted and propagated. From 2015 to 2020, the main ...

Phytochemical research of the roots of Juglans mandshurica Maxim. (Juglandaceae) verified 37 secondary metabolites, including thirteen diarylheptanoids (1-13), five naphthoquinones (14-18), five tetralones (19-23), three lignans (24-26), three phenols (27-29), two anthraquinones (30-31), two...

The study of plant photosynthesis under different degrees of drought stress can provide a deeper understanding of the mechanism of plant drought resistance. In the Taklimakan Desert, saline groundwater is the only local water source with regard to shelterbelt construction and determines plant...

Objective: To explore the feasibility of antioxidant enzymes as germplasm evaluation indices of chestnut (Castanea mollissima) and improve the evaluation system of excellent germplasm resources. Method: Eighteen chestnut germplasms were collected in the areas of Yanshan Mountains in Hebei Province. ...

Aralia elata is a perennial woody plant of the genus Aralia in the family Araliaceae. It is rich in saponins and therefore has a wide range of pharmacological effects. Here, we report a high-quality reference genome of A. elata, with a genome size of 1.21 Gb and a contig N50 of 51.34 Mb, produced...

Intercropped trees are becoming popular as an ecological protection screen for a desert oasis from wind-blown sand and sand erosion. However, trees also consume a large amount of water and thus could compete for water resources with other crops. Here, we evaluated the water uptake in a typical...
