Characterization, Epidemiology, and Management

Characterization, Epidemiology and Management is the third volume in the Phytoplasma Diseases in Asian Countries series dedicated to the analysis of plant pathogens across Asia. Highlighting genomic studies and molecular approaches for rapid detection of phytoplasma diseases, the book discusses effective control measures for insect vectors across Asia. The chapters in this book discuss the latest biological controls and how best to manage and even eliminate phytoplasma diseases. This is an essential read for students, researchers and agriculturalists interested in plant pathology.

Phytoplasma are microorganisms that are transmitted by insect vectors, infecting various different types of annuals and perennials and causing serious damage to crops across Asia.

Dr. Kenro Oshima is Plant Pathology professor at the Hosei University, Japan. He has 20 years of research experience on plant pathology especially on the genomes and pathogenicity of phytoplasmas. He has more than 60 peer reviewed international publications and has delivered numerous oral and posters presentations in national and international meetings. He and his group determined the first complete genome sequence of phytoplasma and found that the phytoplasma has lost many genes of metabolic pathway in the process of evolution. They also discovered the virulence factors of phytoplasmas such as TENGU and PHYL1 and clarified its mechanism of action. He is a member of the International Phytoplasma Working Group (IPWG) andhas participated in the revision of the ‘Candidatus Phytoplasma’species description guidelines in 2022. He is an Associate Editor of Frontiers in Microbiology for the section of Evolutionary and Genomic Microbiology. He was awarded as Kitamoto Award from Japanese Society of Mycoplasmology in 2018 and the Society Award from Phytopathological Society of Japan in 2021.

Amit Yadav, Ph. D. is a Scientist at National Centre for Cell Science at Pune, India. He carried out his doctoral studies on ‘Sugarcane Grassy Shoot’ (SCGS) phytoplasma from University of Pune, Pune. Currently, his research group is involved in perusing research on ‘Candidatus phytoplasma’ involving the functional genomics, epidemiology, detection and diagnosis, plant-insect-phytoplasma interactions, and taxonomy. ‘Candidatus Phytoplasma’ is a ‘not-yet-cultured’ plant pathogenic bacteria involved in devastating diseases in economically important plants across the globe. Dr Yadav is currently working on epidemiology of Sandalwood Spike Disease related to ‘Ca. P. asteris’ and genome characterisation of Peanut Witches’ Broom (PWB) phytoplasma associated with Glycine max and Parthenium hysteroporous. He has published 58 peer-reviewed research articles which includes the reports on phytoplasma diseases on different plant species, phytoplasma genome sequencing and genome characterizations. He is review editor of specialty section in Frontiers in Microbiology: Microbe and Virus Interactions with Plants and Evolutionary and Genomic Microbiology (specialty section of ‘Frontiers in

Microbiology’, ‘Frontiers in Genetics’ and ‘Frontiers in Ecology and Evolution). Also, he is editorial member of ‘Phytopathogenic Mollicutes’, a journal dedicated to phytoplasma studies. Dr Yadav is a member of Bergey's International Society for Microbial Systematics (BISMiS), Association of Microbiologists of India (AMI), Indian Association of Mycoplasmologists (IAM), International Organization of Mycoplasmology (IOM) and a member of board of studies in Botany at Sir Parashurambhau College, Pune.

Seyyed Alireza Esmaeilzadeh-Hosseini, PhD. started working as a researcher in the Plant Protection Research Dept., Yazd Agricultural and Natural Resources Research and Education Center, AREEO, Yazd, Iran since 2000. Currently, he is a member of the academic staff and the head of the center. He has also taught plant virology and phytopathogenic prokaryotes courses in the universities of Yazd province. Dr. Esmaeilzadeh-Hosseini is reviewer of several international and national journals. He has participated in more than 52 research projects in the field of plant pathology, especially phytoplasma diseases. He has participated in the publication of more than 61 research articles in reputed national and international journals and also contribution to 76 paper presentation in national and international scientific congresses. Dr. Esmaeilzadeh-Hosseini has won the top position among the researchers of the universities of Yazd province and the researchers of the Iranian Research Institute of Plant Protection (IRIPP) several times. He is a member of the International Phytoplasma Working Group (IPWG) and has participated and presented papers in the 2nd to 4th IPWG Congress. He has introduced some new subgroups of phytoplasmas (16SrXXIX-B, 16SrIX-I and 16SrII-Z) and new hosts of these diseases in the world. He is currently involved in research on the biological and molecular characteristics of phytoplasmas and the management of these diseases in Iran.

Yupa Hanboonsong, Professor in Entomology of the Department of Entomology and Plant Pathology, KhonKaen University. Thailand. She obtained a Ph. D in Entomology from Lincoln University, New Zealand. Prof. Hanboonsong and her research group is a pioneer on sugarcane white leaf disease caused by phytoplasma. Her research group contributed essential new knowledge and a better understanding about this sugarcane phytoplasma disease and its epidemiology including identification of new disease vectors, mode of transmission of the pathogen, the description of probing activities pattern of the vector and working out various measures for integrated management of the disease. Her research findings on sugarcane white leaf management expanded to other Asian countries for insect vectors and sugarcane white leaf disease control. Last year (2021) she has published a manual on new norm of seed cane propagation for sugarcane white leaf management and her new method of seed cane production for reducing sugarcane white disease is well known and practiced by sugarcane farmers in Thailand. Dr. Hanboonsong is also a member of the scientific board committee on sugarcane white disease management in Thailand under the office of cane and sugar board of the Ministry of Industry, Thailand. She is also member of the editorial board for the International Journal Sugar Tech.
