G proteins are the key regulators for a wide range of cellular processes in animals and plants. In comparison to animals and yeast, plants have a single Rho-GTPase subfamily called Rho-like GTPases (ROPs). The ROP family of monomeric GTPases has emerged as a versatile and key regulator in plant signal transduction processes. During the past few years’ studies on plant RHO-type (ROP) GTPase have generated new insights into their role in diverse processes ranging from cytoskeletal organization, polar growth, development to stress and hormonal responses. Studies have shown that plants have evolved specific regulators and effector molecules. ROP GTPases possess the ability to interact with these multiple regulator and effector molecules that ultimately determines their signaling specificity. Recently, genome wide studies in plants have shown that the Arabidopsis genome encodes 93, and rice has nearly 85 small GTPase homologs. And we have been able to identify four new homologs in the rice genome. Here, we focus on the complete phylogenetic, domain, structural and expression analysis during stress and various developmental processes of small GTPases in plants. The comparison of gene expression patterns of the individual members of the GTPase family may help to reveal potential plant specific signaling mechanisms and their relevance. Also, we are summarizing the role of currently known ROP GTPases and their interacting proteins with brief description, simultaneously, comparing their expression pattern based on microarray data. Overall, we will be discussing the functional genomic perspective of plant Rho like GTPases and their role in regulating several physiological processes such as stress, hormonal, pollen tube, root hair-growth and other developmental responses.
Calcium plays pivotal role in regulating the physiological as well as developmental processes in plants. Till now, several calcium sensors have been discovered, which regulate the diverse signaling pathways involved in plant growth and development. One of the major calcium sensors CBL (calcineurin B-like) is decoding the calcium signal during various environmental stresses in plants. Calcium mediated signal is transduced downstream by CBL-interacting protein kinases (CIPKs), which generally phosphorylate the target proteins such as transcription factors or transporters/channel leading to a response. Mutant based approach has provided valuable information in the functional analysis of individual members of CBL and CIPK gene family in Arabidopsis. Both CBL and CIPK gene families have previously been identified and characterized in Arabidopsis and rice. Identification and characterization of CBLs and CIPKs in other plant species such as Oryza sativa, Pisum sativum, Cicer arietinum, Zea mays, Populus euphratica, Vitis vinifera, Malus domestica, Gossypium hirsutum, Sorghum bicolor, Brassica napus, Vicia faba, Phaseolus vulgaris, Ammopiptanthus mongolicus and Triticum aestivum are still in juvenile stage. Overall, Global Comparative Analysis of CBL-CIPK Gene Families in Plants is a comprehensive study focused on the diverse role of CBL-CIPK module in different stress signaling and also to identify a newly emerging role of this calcium-signaling module in plant growth and development across different plant species. In addition, beside Arabidopsis, it will provide backbone of knowledge to perform a detail molecular investigation in crop plant species and could possibly enable in designing strategies to tame abiotic stress tolerance and development in important agronomical crop plants. This book will act as handy and informative source in this field for students as well as advanced researchers.
This book gives an overview of various interactomes involved in dorsal ventral (DV) and anterior posterior (AP) guidance, their mechanisms of action, subcellular localizations, and functional roles. It will provide readers a better understanding of the development of the nervous system, which in turn will help to find cures to various neural and other disorders. In nematodes there are two types of guidance systems, including DV and AP guidance. The signaling process that guides the growth cones along the DV axis has remained intact in both vertebrates and invertebrates. The adaptor protein UNC-53 appears to play a part in migration along the AP axis in both worms and their human homologs. “Neuron Navigators” (NAV) are also involved in nervous system development
Preface: Competitive sessional and semester exams are a window to evaluate the aptitude of students towards achieving higher academic goals at different levels. Universities and institutes of learning and repute provide for students to be admitted in M. Pharmacy based on GPAT score. Along with this GPAT score is considered essential for awarding fellowships to pursue further education in reputed universities, Central research institutes and institutes of national importance. The authors have compiled this book with a specific orientation towards Pharmaceutics specially designed with MCQ questions for the guidance of candidates as per the recent syllabus. The authors are quite hopeful that this edition will not only serve the need for sessional and semester exams but will greatly help serve the need for GPAT and other competitive examinations held for recruitment purposes. Our modest aim in writing this book is to produce a test pattern guide for Pharmacy students appearing in exams at different levels.
Most people view cultural heritage sites as static places, frozen in time. In Cultural Landscapes in India, Amita Sinha subverts the idea of heritage as static and examines the ways that landscapes influence culture and that culture influences landscapes. The book centers around imagining, enacting, and reclaiming landscapes as subjects and settings of living cultural heritage. Drawing on case studies from different regions of India, Sinha offers new interpretations of links between land and culture using different ways of seeing—transcendental, romantic, and utilitarian. The idea of cultural landscape can be seen in ancient practices such as circumambulation and immersion in bodies of water that sustain engagement with natural elements. Pilgrim towns, medieval forts, religious sites, and contemporary memorial parks are sites of memory where myth and history converge. Engaging with these spaces allows us to reconstruct collective memory and reclaim not only historic landscapes, but ways of seeing, making, and remembering. Cultural Landscapes in India makes the case for reclaiming iconic landscapes and rethinking conventional approaches to conservation that take into consideration performative landscape as heritage.
This book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.
This text discusses the principal political and constitutional questions that have arisen in the states of Bangladesh, India, Pakistan and Sri Lanka following fifty years of independence. In Sri Lanka the pressing problems have been around the inter-ethnic civil war, experiments with constitutional designs, widespread prevalence of corruption and the recrudescence of Buddhist militancy. In India it has been corruption, Hindu nationalism and general political instability. In Bangladesh and Pakistan it has been the role of the military, the state and religion. A general theme is an analysis of the malaise that is prevalent and how and why this was inherited, despite the colonial legacy of parliamentary democracy, the steel framework of a trained bureaucracy, the independence of the judiciary and the rule of law.
Ever heard about the four corners of the circle? Since childhood, it has been taught in schools that the circle has no corners. Life is a never-ending marathon. It keeps on revolving in circles, and everyone is in search of a final destination, a corner, that they never reach. This book is a small initiative to throw light on different aspects of the education system and how could we join hands to make it more productive. It guides the aspiring students to follow a right approach, take correct decisions, and overcome distractions in their career. It advocates that the educational institutions should focus on enlightening the lives of the students by providing quality education, quality learning ambience, practical grounds to implement class room theories, and by helping students convert their black cat into a white one. The book is neither biased toward students nor educational institutes; the sole purpose is to provide their individual perspectives and reach to a common conclusion. The book contains five theories, which Mr. Mohit Jain has discovered in his sixteen years of teaching experience and which would help the youngsters reach closer and closer to their goals. This book is about us.
