Toonamicrocarpavarin (1), a new tirucallane-type triterpenoid, along with eight known ones, piscidinol A (2), toonaciliatavarin E (3), toonayunnanin A (4), 7-acetyneotrichilenone (5), hispidol A (6), odoratone (7), phellochin (8), toonaciliatavarin D (9), were isolated from T. ciliata. Their...

Trunk sap flow rate is a key indicator for judging the strength of root water absorption and transpiration, and is widely used in the study of tree transpiration water consumption. At present, the plant sap flow meters are generally imported equipment with high prices and a single type of sampling...

The dependence of inter-annual ecosystem evapotranspiration (ET) partitioning on vegetation dynamics is crucial for understanding the long term coupling relationship between the water and carbon cycles. The objective of this study was to determine the spatial variation of ET partitioning (T/ET) and ...

Plant community formation is determined by plant competition, while the water uptake depth of vegetation is regarded as a critical factor in maintaining species coexistence under competition. However, the source variation of montane plant water uptake remains poorly understood, especially under the ...

Clarifying the genetic relationship and divergence among Curcuma L. (Zingiberaceae) species around the world is intractable, especially among the species located in China. In this study, Reduced Representation Sequencing (RRS), as one of the next generation sequences, has been applied to infer...

The tung tree (Vernicia fordii Hemsl.), an economically important woody oil plant, produces excellent fast-drying oil from the seeds which has been used as a protective finish on projects and surfaces for centuries. Knowledge of sex determination and flower development of tung trees is helpful for...

Phytochemical investigation of Eucommia ulmoides Oliver staminate flowers provided twenty-seven compounds, including 11 triterpenes (1-11), 4 fatty acids (12-15), 1 coumarin (16), 1 chromone (17), 7 flavonoids (18-24) and 3 cyclopeptide alkaloids (25-27). Compounds 4-6, 8-9, 11-15, 17 and 25-27...

Objective: The aim of this study was to explore the changes and responses of hydraulic characteristics of plants under different levels of drought stress, and their ability to repair embolism after rehydration, thereby providing theoretical hydraulic evidences for plants to adapt to drought...

Objective: To study the function of phytochrome interacting factor (PIF) in Populus. Method: The molecular characteristics analysis of PIF was conducted, including gene family members, gene structure and conserved motifs. The expression profiles of PIF family members in different tissues were...
