2025-06-09Official Publication of "Atlas of Compositae Plants in China"The "Atlas of Compositae Plants in China" systematically summarizes the classification information of Chinese Compositae plants, encompassing 296 genera and 2,533 species. Of these, 278 genera and 1,830 species are accompanied by color illustrations and textual descriptions. I. Overview"Atlas of Compositae Plants in China," a monumental work systematically summarizing the classification information of Chinese compositae plants, has recently been officially published by Henan Science and Technology Press. Edited by Researcher Chen Yousheng and Associate Researcher Wang Long from the South China Botanical Garden, ...Read More -
2025-06-05Seasonal Variation of Phyllosphere Microbial Communities Under WarmingThe phyllosphere, as one of the major habitats for microorganisms and sensitive to temperature and moisture, so understanding its response to climate warming and variable moisture associated with changes in seasons, is crucial to predicting ecosystem function. We found that phyllosphere microbial communities exhibited pronounced seasonal variati... The phyllosphere, as one of the major habitats for microorganisms, plays a crucial role in maintaining plant health and ecosystem functionality. Given its high sensitivity to changes in temperature and humidity, understanding the phyllosphere’s response to climate warming and seasonal humidity fluctuations is vital for predicting ecosystem func...Read More -
2025-06-02Overexpression of anthocyanin activator LrAN2 improving black goji berry (Lycium ruthenicum) seedling tolerant to cadmium stressLrAN2 is well-known to activate the biosynthesis of anthocyanin in black goji berry (Lycium ruthenicum). Overexpressing LrAN2 enhance black goji berry seedling tolerant to cadmium stress through optimizing redox homeostasis, promoting growth thereby diluting cadmium toxicity, and sequestrating cadmium into vacuole. Plant and soil exposed to heavy metals such as cadmium (Cd) threaten the environment and human health. It remains unknown whether or not MYB-type anthocyanin regulator AN2 play a role in tolerance to Cd stress. In this study, overexpression of Lycium ruthenicum AN2 (OE-LrAN2) enhance transgenic seedlings tolerant to Cd stress, which may contribu...Read More -
2025-05-20Novel Cuproptosis-Inhibitory Triketone-sesquiterpene Conjugates Corymbinols A and B from the Fruits of Corymbia citriodoraCorymbinols A (1) and B (2a/2b), novel bis-β-triketone hybrids fused with sesquiterpene and chalcone units, were isolated from Corymbia citriodora fruits. Corymbinols A inhibited cuproptosis in HepG2 cells by 31% at the concentration of 20 μM, implying the potential as a non-toxic therapeutic against liver vancer.

2025-05-20Spatial Differentiation of Glomalin-Related Soil Proteins in Tropical Montane RainforestsGRSP and GRSP/SOC exhibited strong spatial autocorrelation, with contrasting topographic trends: GRSP peaked in ridges but was lowest in valleys, whereas GRSP/SOC was highest in valleys. Soil total nitrogen, available phosphorus, and pH were key predictors of GRSP in ridges, while pH was the critical predictor of GRSP/SOC in valleys. A research team from the South China Botanical Garden (SCBG) of the Chinese Academy of Sciences has uncovered the spatial variation patterns of glomalin-related soil proteins (GRSP) in tropical montane rainforests and their contribution mechanisms to soil organic carbon (SOC). The study, conducted in the 60-hectare Jianfengling tropical montane ...Read More -

2025-05-09Plant Traits Remain Stable After 18 Years of Nitrogen Addition in a Tropical ForestAn 18-year nitrogen (N) addition experiment in a tropical nitrogen-saturated forest reveals that plant morphological and physiological traits remain largely stable across trees, shrubs, and herbs. Leaf traits better distinguish plant functional groups than root traits, and nutrient acquisition strategies indicated by leaf or root economics spect... As global atmospheric nitrogen deposition intensifies, its ecological impact on nitrogen-limited regions is well-documented. However, how prolonged nitrogen inputs affect plant functional traits in already nitrogen-saturated ecosystems remains uncertain. To explore this, researchers from the South China Botanical Garden, Chinese Academy of Scien...Read More
