Phylogeny, taxonomy, and biogeography of Pterocarya (Juglandaceae)

Song, Yi-Gang ; Li, Ying ; Meng, Hong-Hu ; Fragnière, Yann ; Ge, Bin-Jie ; Sakio, Hitoshi ; Yousefzadeh, Hamed ; Bétrisey, Sébastien ; Kozlowski, Gregor

In: Plants, 2020, vol. 9, no. 11, p. 1524

Relict species play an important role in understanding the biogeography of intercontinental disjunctions. Pterocarya (a relict genus) is the valuable model taxon for studying the biogeography of East Asian versus southern European/West Asian disjunct patterns. This disjunction has not been as well studied as others (e.g., between Eastern Asia and North America). Several phylogenetic studies...

Shining a light on species delimitation in the tree genus Engelhardia Leschenault ex Blume (Juglandaceae)

Zhang, Can-Yu ; Low, Shook Ling ; Song, Yi-Gang ; Nuraina ; Kozlowski, Gregor ; Do, Truong Van ; Li, Lang ; Zhou, Shi-Shun ; Tan, Yun-Hong ; Cao, Guan-Long ; Zhou, Zhuo ; Meng, Hong-Hu ; Li, Jie

Enhanced efficacy in species delimitation is critically important in biology given the pending biodiversity crisis under global warming and anthropogenic activity. In particular, delineation of traditional classifications in view of the complexity of species requires an integrative approach to effectively define species boundaries, and this is a major focus of systematic biology. Here, we...

High-risk KPC-producing Klebsiella pneumoniae lack type I R-M systems

Zhou, Ying ; Tian, Dongxing ; Tang, Yu ; Yu, Lianhua ; Huang, Yunkun ; Li, Gang ; Li, Meng ; Wang, Yong ; Yang, Zehua ; Poirel, Laurent ; Jiang, Xiaofei

In: International Journal of Antimicrobial Agents, 2020, vol. 56, no. 2, p. 106050

Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) have disseminated worldwide and are a major threat to public health. The multidrug- resistant (MDR)-phenotype of KPC-KP are commonly associated with the presence of high molecular weight blaKPC plasmids. Restriction-modification (R-M) systems provide bacteria with innate defense against plasmids or other infectious gene...

Online newspaper framing of non-communicable diseases : comparison of mainland China, Taiwan, Hong Kong and Macao

Chang, Angela ; Schulz, Peter J. ; Cheong, Angus Wenghin

In: International journal of environmental research and public health, 2020, vol. 17, no. 15, p. 15 p

As non-communicable diseases (NCDs) are now well recognized as the leading cause of mortality among adult populations worldwide, they are also increasingly the focus of media coverage. As such, the objective of this study is to describe the framing of NCDs in the coverage of newspapers, with the understanding that it says something about the society producing it. Automatic content analysis was ...

The type I-E CRISPR-Cas system influences the acquisition of bla KPC-IncF plasmid in Klebsiella pneumonia

Zhou, Ying ; Tang, Yu ; Fu, Pan ; Tian, Dongxing ; Yu, Lianhua ; Huang, Yunkun ; Li, Gang ; Li, Meng ; Wang, Yong ; Yang, Zehua ; Xu, Xiaogang ; Yin, Zhe ; Zhou, Dongsheng ; Poirel, Laurent ; Jiang, Xiaofei

In: Emerging Microbes & Infections, 2020, vol. 9, no. 1, p. 1011–1022

Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) have disseminated worldwide and emerged as major threats to public health. Of epidemiological significance, the international pandemic of KPC-KP is primarily associated with CG258 isolates and bla KPC-IncF plasmids. CRISPR-Cas system is an adaptive immune system that can hinder gene expansion driven by horizontal gene ...
