2019-07-22Engineering low-cadmium rice through expression of OXS3-family member genesAuthor: WANG Changhu E-mail: cwang@scbg.ac.cn Paper link: https://www.sciencedirect.com/science/article/pii/S1871678417305198 Exposure to cadmium (Cd), a toxic heavy metal classified as a group 1 carcinogen can lead to cancer, osteoporosis and renal disorder.Read More
Contamination of soil with Cd results in human dietary intake from plant-derived food, with rice as the major source of dietary Cd for nearly half of the world’s population that relies on it as a staple.

2019-07-19Urbanization intensifies phosphorus (P) limitation in subtropical forest ecosystemsAuthor: HUANG Juan E-mail: lotus-hj@scbg.ac.cn Paper link: https://www.sciencedirect.com/science/article/pii/S0048969719323721?via%3Dihub Urbanization, the migration of populations from rural to urban areas, has been causing great stress on natural environments, leading to air pollution and nitrogen (N) deposition, negatively affecting forest health. Although there is evidence that urbanization has changed forest N cycling, little is known about whether urbanization also changes t...Read More

2019-07-17Global Pattern and Controls of Biological Nitrogen Fixation under Nutrient EnrichmentAuthor: ZHENG Mianhai E-mail: zhengmianhai@scbg.ac.cn Paper link: https://doi.org/10.1111/gcb.14705 Biological nitrogen (N) fixation (BNF), an important source of N in terrestrial ecosystems, plays a critical role in terrestrial nutrient cycling and net primary productivity. Currently, large uncertainty exists regarding how nutrient availability regulates terrestrial BNF and the drivers responsible for this process.Read More

2019-07-08Researchers Reveal Contributions of Competition and Climate on Radial Growth of Pinus Massoniana in Subtropics of ChinaAuthor: LIANG Hanxue E-mail: hanxuel@scbg.ac.cn Paper link: https://doi.org/10.1016/j.agrformet.2019.04.014 The limiting factor of tree growth in subtropical regions of China has not been conclusive. Numerous studies have shown that climate is not the primarily limit factor of tree growth. Therefore, it is widely speculated that competition may play a vital role, but there is no relevant report at present, and there is no more quantifying the effect.Read More

2019-07-02Distinct Responses of Soil Fungal and Bacterial Nitrate Immobilization to Land Conversion from Forest to AgricultureAuthor: LI Xiaobo E-mail: lixiaobo@scbg.ac.cn Paper link: https://www.sciencedirect.com/science/article/pii/S0038071719300847 Forest conversion to agriculture has recently been found to result in a substantial decrease in microbial nitrate (NO3-) assimilation in soil, which is a key cause of NO3- accumulation and thus increases the risk of nitrogen losses from agricultural soils.Read More
However, how and why the respective NO3- assimilation of fungi and bacteria, the domin... -
2019-06-18Leaf Mechanical Strength Varies Independently with Photosynthetic CapacityOne research paper published in New Phytologist describes the independent relationship between leaf mechanical strength and photosynthetic capacity across 57 woody species with contrasting light requirements in Dinghushan Biosphere Reserve.

One research paper published in New Phytologist describes the independent relationship between leaf mechanical strength and photosynthetic capacity across 57 woody species with contrasting light requirements in Dinghushan Biosphere Reserve.Read More
Forest species can be clarified as either ‘light demanding’ or ‘shade tolerant’ according to their... -
2019-06-06Soil Moisture Drives Microbial Controls on Carbon Decomposition in SubtropicsAuthor:Huang Wenjuan E-mail:wjhuang@scib.ac.cn Paper link:https://www.sciencedirect.com/science/article/abs/pii/S0038071718304279 Researchers provide strong evidence of microbial control over soil carbon (C) decomposition and suggest the future trajectory of soil C may be more responsive to changes in soil moisture than temperature in subtropics. Researchers from Dinghushan Forest Ecosystem Research Station of South China Botanical Garden, Chinese Academy of Sciences (SCBG) provide strong evidence of microbial control over soil carbon (C) decomposition and suggest the future trajectory of soil C may be more responsive to changes in soil moisture than temperature in subtropics.Read More

2019-05-22Interactive effects of nitrogen and phosphorus additions on plant growthJIANG Jun performed a meta-analysis of 133 independent studies conducted in four natural terrestrial ecosystems to examine the interactive effects of N and P additions on ten plant growth-related variables. Author: JIANG Jun E-mail: jiangjun@scbg.ac.cn Paper link: https://doi.org/10.1007/s11104-019-04119-5 Plant growth in terrestrial ecosystems is commonly limited by nitrogen (N) or phosphorus (P). At high latitudes, temperature is low, soil N mineralization is also low, and plant growth is often limited by available N. In tropical forests on old soils, available soil P is low, and plant growth is often limited by P. In recent years, co-limitation...Read More
