2021-05-11A New Mechanism of Light Signal Inhabits Brassinosteroids Pathway during PhotomorphogenesisAuthor: ZHANG Wenbin E-mail: 215867397@qq.com Paper link: https://academic.oup.com/plcell/advance-article/doi/10.1093/plcell /koab112/6237499 Online time: 19 April 2021 Plant seedlings generally undergo a series of developmental changes to seek light from seed germination to seedling emergence. Once exposed in the light, plants undergo a series of photomorphogenic responses, which require to quickly remove the repressors accumulated in the dark and activate the related promotors. Brassinosteroids, one of the ma...Read More

2021-04-21Interactions between nitrogen and phosphorus additions affect belowground carbon-cycling processesAuthor: JIANG Jun E-mail: jiangjun@scbg.ac.cn Paper link: https://doi.org/10.1016/j.soilbio.2021.108216 Online time: 16 March 2021 Nitrogen (N) and phosphorus (P) are two most commonly limiting nutrients for the growth and reproduction of photosynthetic biota. Increased supplies of N, P, or both are expected to exert substantial impacts on growth and metabolism of plants and soil microbes, therefore terrestrial carbon (C)-cycling. While responses of aboveground C processes ...Read More

2021-04-19Nitrogen enrichment stimulates soil aggregation and enhances carbon storage in terrestrial ecosystems of ChinaAuthor: KUANG Yuanwen E-mail: kuangyw@scbg.ac.cn Paper link: https://doi.org/10.1111/gcb.15604 Online time: 19 March 2021 Soil is a major terrestrial C pool. Nitrogen (N)-induced soil C sequestration has been well documented, however, the underlying mechanisms of how N regulates soil C budgets remain uncertain, which has generated extensive debate about the above and belowground C allocation, in particular under N enrichment.Read More

2021-04-15Tropical Forest Soils Capture CO2 Under Elevated Nitrogen DepositionIn a new study, Dr. LU Xiankai and his colleagues from the South China Botanical Garden (SCBG) of the Chinese Academy of Sciences (CAS) found that tropical forests can capture carbon dioxide (CO2) into soils and thus reduce emitted CO2. But how exactly do tropical forest soils capture atmospheric CO2?Read More

2021-04-01Multiple environmental factors regulate the large-scale patterns of plant water use efficiency and nitrogen availability across China’s forestsAuthor: KUANG Yuanwen E-mail: kuangyw@scbg.ac.cn Paper link: https://iopscience.iop.org/article/10.1088/1748-9326/abe3bb Online time: 2021-2-22 Global changes have profoundly effects on plant water use efficiency (WUE) and N availability (NA) in forests. Large-scale geographic gradients provide an opportunity to determine how global changes affect plant WUE and NA.Read More

2021-03-16Researchers reveal host preference and specialization toward fungal assemblages in mycoheterotrophsAuthor: ZHAO Zhongtao E-mail: zhzht621@scbg.ac.cn Paper link: https://doi.org/10.1038/s41396-020-00874-x Online time: 06 January 2021 Mycoheterotrophs are a group of plants having lost chlorophylls, parasitic on mycorrhizal fungi. They are the ‘aliens’ of the plant world because of their rarity and weird looks. Non-green full mycoheterotrophs live their life completely depending on fungi, usually maintain more specialized fungal relationships than autotrophs: it is thought t...Read More
