Prof. Dr. Xiaofei Cheng | Molecular Biology | Best Research Article Award

Vice Dean | Northeast Agricultural University | China

Professor Xiaofei Cheng is a distinguished molecular plant pathologist and biochemist at the College of Agriculture, Northeast Agricultural University, Harbin, China. His research focuses primarily on the molecular mechanisms underlying plant-virus interactions, with a particular emphasis on host immune modulation, viral pathogenicity, and RNA virus replication and movement. Through extensive collaborative research with national and international institutes, including Agriculture and Agri-Food Canada and the National Centre for Biotechnology (CSIC, Spain), Professor Cheng has made pioneering contributions to understanding how plant viruses exploit host cellular machinery to establish successful infections. A central theme of Cheng’s research involves elucidating how RNA viruses manipulate plant immunity. His team discovered that plant viruses can hijack host phosphatases to attenuate MAPK-mediated immunity, enabling robust infection. Moreover, his studies revealed the existence of pathogen protease-activated molecular decoys, offering potential for engineering customized resistance in plants. Cheng also uncovered viral strategies to target NPR1, a master regulator of salicylic acid (SA)-mediated defense, thereby suppressing antiviral immunity. His research extends to virus-encoded small proteins, viral replication vesicle formation, and intercellular virus movement. Earlier, Cheng’s work demonstrated that sumoylation of viral RNA polymerase promotes infection by subverting NPR1-mediated immunity, and that viral suppressor proteins such as VPg can degrade key host silencing factors via autophagy pathways. With over 96 publications, 1,635 citations, and an h-index of 23 (Scopus), Professor Cheng has established himself as a leading figure in molecular plant virology and biotechnology. His findings not only deepen our understanding of host-pathogen molecular interplay but also pave the way for developing virus-resistant crop varieties, contributing significantly to global agricultural sustainability.
