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). James F. White is professor of Plant Biology at Rutgers University, New Brunswick, NJ, United States. He received his BS and MS degrees in Botany and Plant Pathology/Mycology from Auburn University, Alabama, and completed his PhD in Botany at the University of Texas at Austin in 1987. Dr. White is internationally recognized for his research on symbiosis, with a focus on endophytic microorganisms. He has authored numerous scientific articles and has written or edited several influential reference books on the biology, taxonomy, and phylogeny of microbial endophytes. He and his research group currently investigate the diversity of endophytic and biostimulant microbes and their functional impacts on host plants, contributing foundational knowledge to plant–microbe interaction biology and sustainable agricultural innovation.
