China's 19-year City-level Energy-related Carbon Emissions：Characteristics, Driving Forces And Regionalized Mitigation Polices

Carbon dioxide (CO2) emission, responsible for more than 60% of green house effects, was proved to be the leading contributing factor for global warming. China, which has been experiencing a remarkable growth of gross domestic product (GDP), has surpassed the United States and became the largest CO2 emitter, sharing 24.2% of the world's tota...

Rice is the major pathway for Cd and Pb exposure in the population near mining area in South China

　　Heavy metal contamination by mining is a major environmental concern on a global scale. As a result, health related incidents caused by heavy metal pollution in China have risen sharply since 2005, with major accidents attracting nationwide attention. It was reported that high Cd in rice on the Chinese market was mainly the result of contam...

Plant and Microbial Responses to Nitrogen and Phosphorus Addition Across an Elevational Gradient in Subarctic Tundra

Temperature is a major limiting factor for high latitude communities and ecosystems such as subarctic tundra, and these systems are therefore predicted to be particularly responsive to global warming. Increasing elevation is associated with a decline in temperature, so elevational gradients represent powerful natural experiments which may inform...

Earthworms facilitate net carbon sequestration in soil

Professor Shenglei Fu's group from South China Botanical Garden, Chinese Academy of Sciences (SCBG), together with colleagues from University of Georgia and US Environmental Protection Agency etc., reveal that earthworms facilitate net carbon sequestration in soil, although the humble animals are often found stimulating CO2 emissions. This findi...

Maintenance of a Living Understory Enhances Soil Carbon Sequestration in Subtropical Orchards

Agroforestry systems play a central role in the global carbon (C) cycle and contain approximately 12% of the Earth’s terrestrial C. Agroforestry is a management system that integrates trees with farms in an agricultural landscape and usually encompasses a wide variety of understory vegetation management methods. Many studies have shown that man...

Hydrogen (H2) was found to be involved in phytohormone signaling

There is a close relationship between gas and organisms. Besides the involvement of carbon dioxide (CO2) and oxygen (O2) in photosynthesis, other gases, such as hydrogen (H2), methane, ethylene, carbon monoxide (CO) and hydrogen sulfide (H2S) are proved to be involved in various biological activities. From an evolutionary perspective, the origin...

Studies Reveal Rice Genes for Iron-Sulfur Cluster assembly are Responsive to Abiotic Stress

Iron-sulfur proteins are a group of proteins containing iron-sulfur cluster (Fe-S cluster) as cofactors. These proteins play important roles in photosynthesis, respiration, and DNA repair. About 43 genes have been identified to be the Fe-S cluster assembly genes in Arabidopsis genome. As the most important crop in Asia, rice is vital for iron nu...

Efficient protocol for the high-frequency regeneration of C. niditissima

Camellia nitidissima Chi, an evergreen shrub or small tree with golden-yellow flowers, is a rare and endangered ornamental species. It is honored as “the Queen of Camellia” and “the Giant Panda of the Plant Kingdom”. Due to increasing anthropogenic pressure, deforestation and destructive collection of seedlings, its natural population size h...
