M. Iqbal R. Khan is an Assistant Professor of Botany at Jamia Hamdard, New Delhi, India. His current research interests are elucidation physiological and molecular mechanisms associated with abiotic stress tolerance in plants. Dr. Khan has found a significant role of phytohormones in the regulation of plant growth and development, have suggested that phytohormones play an important in controlling stress responses, and interacts in coordination with each other for defense signal networking to fine tune tolerance mechanisms. He is also exploring the regulatory role of other plant signalling molecules and their impact on plant homeostasis especially source-sink relationship under abiotic stresses. Dr. Khan has published more than 50 journal articles, 08 book chapters and has edited five books. He has been recognized as Young Scientist Platinum Jubilee Award, The National Academy of Sciences, India (NASI), Young Scientist of the Year, Indian Society of Plant Physiology and Scientific and Environmental Research Institute, India and Junior Scientist of the Year from National Environmental Science Academy New Delhi, India. Additionally, he is Associate Editor- Journal of Plant Growth Regulation, and 3Biotech. Dr. Noushina Iqbal is currently working as SERB-National Post-Doctoral Fellow in Jamia Hamdard, India. During her PhD, she received the UGC-BSR Fellowship for meritorious student and worked on an UP-CST funded research project. She also got the prestigious Senior Research Fellowship (SRF) by CSIR. She has more than 30 peer reviewed international publications and has authored 1 book and edited 3 books. Her research focuses on understanding the mechanisms of hormonal regulation of plant growth with special emphasis on photosynthesis under abiotic stress. The mechanistic approach applied by nutrients and signaling molecules under varied environmental stress is her priority. She deals with crosstalk between hormones for the modulation of nutrient-use efficiency, source-sink relation and abiotic stress tolerance. Dr. Péter Poór is an assistant professor, who has been leading the Plant Stress Physiology and Photosynthesis Research Group at the Department of Plant Biology of the University of Szeged, Hungary since 2017. His main research area is the investigation of plant defense hormones, and a better understanding of plant defense mechanisms, especially in the dark. As a result of his work, he has published more than 80 international scientific publications to date, to which he has received more than 1,000 citations. In addition to his research work, he participates in the lecturer activities of the Department of Plant Biology, including the teaching of plant cell biology, plant anatomy, photosynthesis, and plant stress physiology. His teaching activities were twice recognized with the Golden Chalk Award based on student votes. In addition, he is an active organizer of university public life, as well as takes part in a wide range of scientific dissemination activities and science organization activities. He is the secretary of the Hungarian Free Radical Research Society and a member of the Hungarian Plant Biology Society. He is also a member of the editorial boards of several international journals (e.g. Frontiers in Plant Science, Journal of Plant Growth Regulation). In 2019, he won the János Bolyai Research Scholarship of the Hungarian Science Academy. In 2018, he received the first prize in the Lecture Series of Young Plant Biologists of the Hungarian Plant Biology Society. Antonio Ferrante holds a PhD in advanced technologies in horticultural science from the Scuola Superiore Sant’Anna, Pisa Italy. He was a visiting researcher at the University California, Davis, and a visiting teaching professor with ERASMUS program in Cardiff University (2015) and Almeria University (2017) and has been a member of the scientific committee of several international conferences. He has authored more than 200 international publications in peer-reviewed journals.
