Enterohemorrhagic Escherichia coli (EHEC) O157: H7 is a subset of the Shiga toxin-producing food-borne pathogen that causes diarrhea, hemorrhagic colitis and hemolytic uremic syndrome. The reservoirs of EHEC O157: H7 are ruminants, mainly bovine. Bovine vaccination has been used to prevent disease outbreaks, and the current method relies on va...Read More -
2023-11-06Understanding recreational ecosystem service supply-demand mismatch and social groups’ preferences: Implications for urban–rural planningRecreation in nature provides multiple physical and mental health benefits to residents .Spatially quantified the recreation service supply and demand along urban-rural gradients in Beijing-Tianjin-Hebei region and revealed the heterogeneous preferences of different population groups . ？ ？ The study found recreation service imbalance with high... Recreation in nature provides multiple physical and mental health benefits to residents. People in cities, especially large ones, have high demand for natural landscape for recreational purposes. However, these natural landscapes often assemble in rural areas. Considering the mismatch of recreation service supply and demand will provide useful i...Read More -
2023-10-22An earlier start of growing season can affect tree radial growth through regulating cumulative growth rateProfoundly affecting phenology , especially in the Northern Hemisphere .Tree radial growth through decreasing the cumulative growth rate .In general , we determined that an earlier SoGS influences tree radial growth by regulating.And red arrows representing negative and positive effects , respectively .Read More
Climate change is profoundly affecting phenology, especially in the Northern Hemisphere. Nevertheless, how tree radial growth responds to phenological shifts remains to be explored. The boreal forest in the Northern Hemisphere is one of the largest biological communities on Earth, and its tree growth dynamics are significant for global chan... -

2023-09-15From tree to forest: how to understand multiple carbon sink constraints?Terrestrial ecosystems , mainly sequestrate carbon through tree growth , playing an important role in mitigating climate change .Of carbon sinks in Amazon forests is caused by drought-induced tree mortality , which in turn leads to a decrease in forest biomass .Mechanisms of forest carbon sinks to global change .Forest biomass can be significant... Forests are the largest carbon sinks among terrestrial ecosystems, mainly sequestrate carbon through tree growth, playing an important role in mitigating climate change. A recent study in Nature has found that the reduction of carbon sinks in Amazon forests is caused by drought-induced tree mortality, which in turn leads to a decrease in forest ...Read More -
2023-08-24Carbon storage capacity of Castanopsis hystrix plantations at different stand– ages in South ChinaHave drawn huge attention for investigation .Impacts of different stand ages on the C storage capacity of C . hystrix plantations ecosystems , Chinese researchers measured biomass and C content in trees , understory , litter , and soil components from field measurements at different stand ages .Storage capacity in the 6 – , 10 – , 15 – , 25 ... The establishment of forest plantations is an excellent silvicultural alternative to improve atmospheric carbon (C) sequestration for climate change mitigation. In recent years, the importance of forest growth and C dynamics at different stand ages have drawn huge attention for investigation. Castanopsis hystrix (C. hystrix) is an indigenous tre...Read More -
2023-08-21The first telomere-to-telomere haplotype-resolved reference genome of triploid bananaThe article “ Telomere-to-telomere haplotype-resolved reference genome reveals subgenome divergence and disease resistance in triploid Cavendish banana ” has been published in Horticulture Research . This work was supported by the National Natural Science Foundation of China and the Strategic Priority Research Program of Chinese Academy of Sci...Read More
Banana is one of the most important crops of the world. The demand for cultivated bananas continues to grow; however, their production is greatly affected by a complex of biotic and abiotic stresses. For instance, banana yields are severely threatened by the disease fusarium wilt, which is caused by the fungus Fusarium oxysporum f. sp. cube... -
2023-07-06A molecular module in gibberellin signaling-mediated floweringGenes in plants remains unclear .Figure . A proposed model illustrating how the DELLA-BRM-NF-YC module regulates GA signaling-mediated flowering . The timing of floral induction is tightly controlled by environmental cues and intrinsic signals. The critical role of gibberellin (GA) in this process has been extensively studied in the past decades. DELLA proteins serve as the central regulatory hubs of GA signaling. The mechanism of GA-dependent transcription involves the recruitment of DELL...Read More
