This book, titled "Responses of Plants to Environmental Stresses," is a collection of 15 articles that explore various aspects of how plants respond to environmental stresses. The editor, Renata Szymańska, is an expert in plant biochemistry and physiology, focusing on plant responses to environmental stresses, reactive oxygen species, and oxidative stress. The book covers a wide range of topics, including the plasticity of root system architecture and leaf gas exchange parameters in bottle gourd under water deficit, the characterization of isoprene and ocimene-emitting transgenic *Arabidopsis* plants under contrasting environmental conditions, and the genome-wide identification of barley ABC genes and their expression in response to abiotic stress. Other articles delve into the roles of superoxide dismutase genes in *Dendrobium catenatum*, the involvement of an abiotic stress-responsive U-Box E3 ubiquitin ligase in diurnal rhythm regulation, and the responses of *Portulaca* to salt stress. The book also includes studies on the influence of soil acidity on bread wheat cultivars, the responses of upland cotton lines to irrigated and rainfed conditions, and the decomposition of calcium oxalate crystals in *Colobanthus quitensis* under CO₂ limiting conditions. Additionally, it covers chlorophyll a fluorescence transient and 2-dimensional electrophoresis analyses of photosynthesis in *Malus* under heat stress, proteomic analyses of artificial aging in Siberian wildrye seeds, and the function and mechanism of WRKY transcription factors in abiotic stress responses. The book provides a comprehensive overview of the complex mechanisms by which plants adapt to various environmental stresses, making it a valuable resource for researchers and practitioners in the field of plant biology.This book, titled "Responses of Plants to Environmental Stresses," is a collection of 15 articles that explore various aspects of how plants respond to environmental stresses.
