About this ebook

Polyamine-Phytohormone-Nutrient Network: Nexus in Plant Responses to Abiotic Stresses presents the latest global research on the these important tools for improving physiological / biochemical molecular mechanisms for improved plant health and production. Exposure of plants (crop and non-crop) to abiotic stresses is inevitable; hence, impairments in plant growth, metabolism and productivity due to abiotic stresses seem obvious. Naturally, plants are endowed with endogenous chemicals including intracellular messengers and signalling molecules to counteract the potential stress-impacts, protect cellular functions, and grow and produce well. Polyamines (PAs) are low molecular weight nitrogen- containing compounds with aliphatic polycationic properties. In addition to their roles in diverse growth and development processes, Pas(such as putrescine, spermidine, and spermine) have been implicated in improving plant tolerance to abiotic stresses. On the other hand, PAs have their close relation with both phytohormones (such as cytokinins, abscisic acid, auxins, gibberellins and gaseous hormone ethylene), and most mineral nutrients (such as N and S). Interestingly, the interactive response and outcomes of PAs with either phytohormones or mineral nutrients could exhibit synergistic or antagonistic effects. Thus, either the functions of PAs can be modulated by phytohormones and mineral nutrients; or the cellular/organ or whole plant level PAs may potentially affect the role of both phytohormones and mineral nutrients. With a globally diverse team of expert contributors, this book focuses on the PA-phytohormone-mineral nutrient interactions that is significant for establishing connections between nutrient assimilation, C-fixation, and secondary metabolic pathways. - Presents an exhaustive overview of the major abiotic stresses and their impact (and mechanisms) on plant health - Explores the major physiological/biochemical and molecular mechanisms underlying the individual role of polyamines, phytohormones and mineral nutrients in plants stress tolerance - Explains the critical a crosstalk on the physiological/biochemical and molecular interplay between polyamines, phytohormones and mineral nutrients in plants under abiotic stresses

About the author

Dr. Masood, Assistant Professor of Botany at Aligarh Muslim University, is presently working on stress physiology of plants and its regulation through internal factors including phytohormones and nutrients. His main area of research is to analyse the stress-inducedresponses in plants to heavy-metal accumulation and toxicity, mineralnutrient availability in the soil and also the role of phytohormones inregulating the nutrient status of cells and their synergistic effect inalleviating heavy-metal toxicity. His main findings have been reported injournals of repute, including Plant, Cell & Environment, Journal ofExperimental Botany, Environmental and Experimental Botany,Photosynthetica, Plant Signalling and Behaviour, Journal of PlantPhysiology and others.

Prof. Nafees A. Khan research focuses on understanding the mechanisms of hormonal and nutritional regulation of plant growth with special emphasis on abiotic stress vis-a-vis photosynthetic efficiency and abiotic stress tolerance. He has received multiple recognitions of his work including recognition as a top scientist in a study conducted by Stanford University and published in Plos Journal He is highly cited and received a UGC Mid-Career Award in 2018.

Dr. Naser A. Anjum, Assistant Professor of Botany at Aligarh Muslim University, has made significant contributions to the biology of ‘Plant/Crop-Environment Adaptation’. His works have enlightened the physiology and biochemistry of plants/crops, and theiradaptation/tolerance to varied abiotic stress factors and pollutants. Hehas been the pioneer worker to unveil: nano-graphene mediatedoxidative stress, antioxidant metabolism and glutathione-redox system,and also glutathione-independent defense-system significance in foodcrop model. He has also contributed to the field of phytoremediation,and assessed plant/salt marsh macrophyte chemical pollutantsremediationpotential and the underlying physiological/(bio)chemicalmechanisms. Dr. Anjum received prestigious research awards fromPortuguese Foundation for Science and Technology (FCT) (Portugal),Academia Sinica (Taiwan), and the CSIR and DBT, Govt. of India. He is onthe Editorial boards of several journals. He is serving as the ManagingEditor of Plant Growth Regulation; and Associate Editor of InternationalJournal of Plant Biology, Frontiers in Agronomy, and Frontiers in MarineScience.

Dr. Vasileios Fotopoulos is Associate Professor inStructural and Functional Plant Biology and head of the CUT Plant StressPhysiology Group at Cyprus University of Technology. His main scientificresearch focuses on the study of nitro-oxidative signaling cascadesinvolved in the plant’s response to stress factors, with special emphasison the development of chemical, biological and nanotechnologicalpriming technologies ameliorating abiotic stress factors and promotingplant growth. In addition, he is studying plant secondary metabolismand antioxidant responses in fruit crops during ripening.
