2020-12-29Calculation of fungal and bacterial inorganic nitrogen immobilization rates in soilAuthor: LI Xiaobo E-mail: lixiaobo@scib.ac.cn Paper link: https://doi.org/10.1016/j.geoderma.2020.114450, https://doi.org/10.1016/j.soilbio.2020.108114. Online time: 15 December 2020 The microbial immobilization of inorganic nitrogen (N) has a vital role in controlling the size of the soil inorganic N pool and is therefore an important mechanism for the retention of N in ecosystems. As the dominant microorganisms in soil, fungi and bacteria are probably the main participants in inorganic N immobilization. However, as a resul...Read More

2020-12-28SCBG researchers reveal the mortality threshold for trees under drought on a global scaleAuthor: LIANG Xingyun E-mail: liangxingyun@scbg.ac.cn Paper link: https://doi.org/10.1111/nph.17117 Online time: 2020-11-29 Many areas on the earth are becoming drier under global warming. Meanwhile, in the past decades, drought-induced forest die-off has been recorded on every forested biome, exerting great effects on biodiversity and ecosystem functions. However, a general understanding of forest vulnerability to drought is lacking, because of our limited understan...Read More

2020-12-25Study: Intraspecific variation of phenological shifts to climate warmingAuthor: SONG Zhuqiu E-mail: songzhuqiu@scbg.ac.cn Paper link: https://doi.org/10.1111/1365-2435.13634 Online time: 2020-7-16 The global temperature has averagely increased by about 0.85°C since the late 19th century, and is projected to likely exceed 1.5°C in the end of the 21st century. The timing of seasonal biological activity such as flowering (i.e. phenology) is a sensitive indicator of the ecological effects of global climate warming. With climate warming, spr...Read More

2020-12-15Research progress on Paphiopedilum armeniacum seed coat lignin biosynthesisAuthor: FANG Lin E-mail: linfang@scbg.ac.cn Paper link: https://bmcgenomics.biomedcentral.com/articles/10.1186/s12864-020-06931-1 Online time: 29 July 2020 Paphiopedilum is an important genus of the orchid family Orchidaceae and has high horticultural value. The wild populations are under threat of extinction because of overcollection and habitat destruction. Mature seeds of most Paphiopedilum species are difficult to germinate, which severely restricts their germplasm conservation and commercial p...Read More

2020-11-30Warming leads to more closed nitrogen cycling in nitrogen-rich tropical forestsAuthor: LIE Zhiyang E-mail: liezhiyang@scbg.ac.cn Paper link: https://doi.org/10.1111/gcb.15432 Online time: 2020-11-3 Nitrogen (N) is a key element regulating forest productivity and feedback to climate warming. Sustained climate warming may have profound effects on N cycling in N-rich tropical forests. However, large uncertainty exists regarding how warming affects the integrated N dynamic in tropical forests, especially on the scale of long-term warming.Read More

2020-11-06The genome assembly provides insights into vitamin C accumulation and fruit softening in guavaAuthor: FENG Chen E-mail: fengchen0215@scbg.ac.cn Paper link: https://doi.org/10.1111/pbi.13498 Online time: 2020-10-24 Guava (Psidium guajava L.) is one of the most economically important plant species in the Myrtaceae family. This species was described by Linnaeus in 1753 based on collections from Asia, but many botanists consider the species to be native to tropical America, with subsequent introductions to many other tropical and subtropical regions throughou...Read More

2020-10-30A genomic approach to characterization of terpene synthase family in orchid Dendrobium officinaleAuthor: YU Zhenming E-mail: zhenming311@scbg.ac.cn Paper link: https://doi.org/10.3390/ijms21155419 Online time: 2020年7月 Terpene synthase (TPS) is a critical enzyme responsible for the synthesis of terpenes, which possess diverse roles in plant growth and development. Although many terpenes have been reported in orchids, limited information is available regarding the genome-wide identification and characterization of the TPS family in the orchid, Dendrobium offici...Read More
