2020-03-12Researchers from SCBG reveal the global pattern of phosphorus limitation on terrestrial natural ecosystemsAuthor: WEN Dazhi E-mail: dzwen@scbg.ac.cn Paper link: https://doi.org/10.1038/s41467-020-14492-w Online time: 2020-1-31 In terrestrial ecosystems, nitrogen (N) and phosphorus (P) have been considered as the most important limiting nutrients of aboveground plant production. P limitation, however, is usually assumed to occur mainly in the strongly weathered lowland tropical regions but rarely elsewhere. Here we report that such P limitation is more widespread and m...Read More

2020-02-25Can In vitro extraction tests predict Cd relative bioavailability in rice?Author: ZHUANG Ping E-mail: zhuangp@scbg.ac.cn Paper link: https://www.sciencedirect.com/science/article/pii/S0048969720309633?via%3Dihub Online time: 20 February 2020. With the development of economy and the acceleration of urbanization, human activities have led to the pollution of harmful heavy metals in large areas of farmland, especially paddy soil. Cadmium (Cd) is a common toxic metal in soil pollution. The nationwide survey of soil pollution in China indicated that the pollution of Cd is very severe, and...Read More

2020-02-20Subtropical forest nitrous oxide emissions under nitrogen deposition and seasonal variations: new insights highlighting roles of soil nitrifiers and denitrifiersTropical and subtropical forests are considered sources of nitrous oxide , one of the greenhouse gases mainly produced via microbial nitrification and denitrification in soil .With a title of “ Seasonal variations in N2O emissions in a subtropical forest with exogenous nitrogen enrichment are predominately influenced by the abundances of soil n... Tropical and subtropical forests are considered sources of nitrous oxide, one of the greenhouse gases mainly produced via microbial nitrification and denitrification in soil. However, in recent decades, the emission of nitrous oxide has been influenced by increasing atmospheric nitrogen (N) deposition primarily due to frequent human activities. ...Read More

Ow ’ s group from the South China Botanical Garden ( SCBG ) under the Chinese Academy of Sciences has established a recombinase-mediated gene stacking system .Obviously , this new approach will be very useful in excising unneeded DNA with a ... In order to speed up the process of developing the crops with multiple transgenic traits, Dr. David W. Ow’s group from the South China Botanical Garden (SCBG) under the Chinese Academy of Sciences has established a recombinase-mediated gene stacking system.Read More
In this system, the Cre recombinase is required to excise DNA no longer needed (such... -

2019-12-31Substrate stoichiometry determines nitrogen fixation throughout succession in southern Chinese forestsAuthor: ZHENG Mianhai E-mail: zhengmianhai@scbg.ac.cn Paper link: https://onlinelibrary.wiley.com/doi/full/10.1111/ele.13437 Online time: 04 December 2019 The traditional view holds that biological nitrogen (N) fixation often peaks in early- or mid-successional ecosystems and declines throughout succession based on the hypothesis that soil N richness and/or phosphorus (P) depletion become disadvantageous to N fixers. This view, however, fails to support the observation that N fixers can remain act...Read More -
