This book explores the intricate mechanisms underlying the stress responses of phototrophs, which play a critical and foundational role in shaping and sustaining life on Earth.

The photoautotrophic entities encounter a spectrum of natural and anthropogenic stresses, inducing a multitude of responses at the physiological, biochemical, genetic, and developmental levels. The comprehension of how these phototrophs adeptly counter stressors transcends mere scientific pursuit; it stands as an essential endeavor for predicting their adaptability in an ever-evolving world and, crucially, for conserving our delicate ecosystems. The book will shed light on the sophisticated interplay of stress signaling pathways and the nuanced engagement of stress-responsive hormones within these life forms. Furthermore, it unveils the cryptic genetic and epigenetic controls dictating stress-related gene expression, yielding profound insights into the enduring recollection of their responses to environmental challenges.

This book is an essential read for researchers, educators, and students alike. It offers a comprehensive panorama of stress biology, unveiling the innermost mechanisms at play within photosynthetic organisms discussing their resilience and adaptation.

Delivers evolutionary outlook to the audience by covering studies from cyanobacteria to higher plants Provides valuable insights into signaling cascades and molecular regulations Explores fundamental and advance research in the topic of stress physiology in photoautotrophs

Autorentext

Dr. Arun Kumar Mishra is a Professor at the Laboratory of Microbial Genetics at Banaras Hindu University, India. His group has been working on several aspects of cyanobacterial metabolisms and stress-signaling attributes. However, in recent times his lab is dedicated to understanding certain key metabolisms and signaling prospects in heterocytous cyanobacteria like regulation of sulfur homeostasis, mechanistic signal transduction of circadian cycle, regulation of nitric oxide signaling mediated by NOS enzyme as well as the pertinence of different cell demise modalities. He and his team confer expertise in proteome and metabolome profiling in cyanobacteria, polyphase-based species identification, microscopy, and genetic manipulation techniques. He has published more than 100 high quality peer-reviewed research articles in various reputed international journals. Further, he has also edited book entitled "Cyanobacteria: From Basic Science to Application" dealing with the current research advancement in cyanobacteria.
