Autopolyploidy-driven range expansion of a temperate-originated plant to pan-tropic under global changeJiliang Cheng, Jun Li, Zheng Zhang, Huan Lu, Guoqi Chen, Beibei Yao, Yingxue Dong, Ling Ma, Xiaoxiao Yuan, Jingxuan Xu, Ying Zhang, Weimin Dai, Xianghong Yang, Lifang Xue, Yu Zhang, Chaobin Zhang, Rodney Mauricio, Gary Peng, Shuijin Hu, Bernal Valverde, Xiaoling Song, Yi Li, Marc Stift & Sheng Qiang
Angiosperms are believed to have emerged initially in the tropics and expanded their distribution range polewards through diverse mechanisms, for example polyploidization-driven cold-tolerance evolution. Reversed expansion from temperate to pantropic climate through a polyploidization-driven shift in heat-tolerance remains largely unknown. Here, we found autopolyploidy in relation to the global expansion of Solidago canadensis from its temperate-climate native range in North American to hot-summer climate in an introduced range. Our cytogeographical study of 2062 accessions from...
Kinetics of SARS-CoV-2 specific IgM and IgG responses in COVID-19 patientsBaoqing Sun, Ying Feng, Xiaoneng Mo, Peiyan Zheng, Qian Wang, Pingchao Li, Ping Peng, Xiaoqing Liu, Zhilong Chen, Huimin Huang, Fan Zhang, Wenting Luo, Xuefeng Niu, Peiyu Hu, Longyu Wang, Hui Peng, Zhifeng Huang, Liqiang Feng, Feng Li, Fuchun Zhang, Fang Li, Nanshan Zhong & Ling Chen
The emerging COVID-19 caused by SARS-CoV-2 infection poses severe challenges to global public health. Serum antibody testing is becoming one of the critical methods for the diagnosis of COVID-19 patients. We investigated IgM and IgG responses against SARS-CoV-2 nucleocapsid (N) and spike (S) protein after symptom onset in the intensive care unit (ICU) and non-ICU patients. 130 blood samples from 38 COVID-19 patients were collected. The levels of IgM and IgG specific to N and...
VCF file of multiple single-cyst-derived Ro1 and Ro2 lines of New York fields on Globodera rostochiensis genomeXiaohong Wang, Huijun Yang, Pierre-Yves Véronneau, David Thurston & Benjamin Mimee
The potato cyst nematode, Globodera rostochiensis, is a regulated pest posing a serious threat to potato production worldwide. Although the endemic pathotype (Ro1) of G. rostochiensis has been confined to New York State for several decades as a result of quarantine regulations and management with resistant potato cultivars, a virulent pathotype, Ro2, has emerged, for which control measures are scarce. The ability to detect Ro2 early in fields is necessary to sustain the success of...
Long-term evidence shows crop-rotation diversification increases agricultural resilience to adverse growing conditions in North AmericaTimothy Bowles, Maria Mooshammer, Yvonne Socolar, Franciso Calderón, Michel Cavigelli, Steve Culman, William Dean, Axel Garcia Y Garcia, Amélie Gaudin, W Scott Harkom, Michael Lehman, Shannon Osborne, G Philip Robertson, Jonathan Salerno, Marty Schmer, Jeffrey Strock, A Stuart Grandy & Craig Drury
A grand challenge facing humanity is how to produce food for a growing population in the face of a changing climate and environmental degradation. Though empirical evidence remains sparse, management strategies that increase environmental sustainability, like increasing agroecosystem diversity through crop rotations, may also increase resilience to weather extremes without sacrificing yields. We used multilevel regression analyses of long-term crop yield datasets across a continental precipitation gradient to assess how temporal crop diversification affects maize...
An experimental application of Hypena opulenta as a biocontrol agent for the invasive vine Vincetoxicum rossicumStuart Livingstone, Sandy Smith, Robert Bourchier, Kathleen Ryan, Adriano Roberto & Marc Cadotte
1. Pre-release testing for biological control agents is focused primarily on assessment of host-range specificity and safety of potential agents. Agent impact is considered pre-release, however the ultimate assessment of an agent must occur following release in the field under the target population levels and conditions of the invaded ecosystems. The invasive Eurasian vine, Vincetoxicum rossicum, has spread aggressively through its invaded range of eastern North America since its initial introduction in the late 1800’s....
