Ajay Kumar is currently an Assistant Professor at the Amity Institute of Biotechnology, Amity University, Noida, India. He previously served as a Visiting Scientist at the Agricultural Research Organization, Volcani Center, Israel (2018–2022), and completed his doctoral research at the Department of Botany, Institute of Science, Banaras Hindu University, Varanasi, India, focusing on plant–microbe interactions. Dr. Kumar’s research expertise spans plant–microbe interactions, microbial biocontrol, postharvest fruit disease management, microbial endophytes of medicinal plants, and cyanobacteria–pesticide interactions. He is a prolific author in leading international journals and is also actively engaged in academic editing with major publishers such as Elsevier, Springer, CRC Press, and Wiley. Dr. Kumar currently serves as an Associate Editor for Frontiers in Microbiology and BMC Microbiology, a Guest Editor for Microorganisms and Plants (MDPI), and a Series Editor for Plant and Soil Microbiome (Elsevier). Dr. Amit Kishore Singh, obtained his doctoral degree in Botany from Banaras Hindu University, then after gained post-doc experience from Agricultural Research Organization, Israel. Currently, he is working as an Assistant Professor (Botany Department) in Kamla Nehru P. G. College, Raebareli, India. Dr. Krishna Kumar Choudhary is Assistant Professor in the Department of Plant Sciences, School of Basic and Applied Sciences, Central University of Punjab, Bathinda, India. After completing his Ph.D. in Botany from Banaras Hindu University, Varanasi, India, Dr. Choudhary has worked as Visiting Scientist, Institute of Soil, Water and Environmental Sciences, Agricultural Research Organisation, Ministry of Agriculture and Rural Development, Israel. Potential of his research is evidenced by the high quality publications in some of the best journals of Botany, Environmental and Agricultural sciences such as Environmental and Experimental Botany, Ecotoxicology and Environmental Safety, Archives of Agronomy and Soil Sciences, Photochemistry and Photobiology etc. along with book chapters. He has received awards for best presentation at both national and international conferences. He is also Review Editor (Environmental Toxicology) of Frontiers in Environmental Science.
