MicroRNAs in Plant Development and Stress Responses (Signaling and Communication in Plants Book 15)

"Precise regulation of gene expression in both time and space is vital to plant growth, development and adaptation to biotic and abiotic stress conditions. This is achieved by multiple mechanisms, with perhaps the most important control being exerted at the level of transcription. However, with the recent discovery of microRNAs another ubiquitous mode of gene regulation that occurs at the post-transcriptional level has been identified. MicroRNAs can silence gene expression by targeting complementary or partially complementary mRNAs for degradation or translational inhibition. Recent studies have revealed that microRNAs play fundamental roles in plant growth and development, as well as in adaptation to biotic and abiotic stresses. This book highlights the roles of individual miRNAs that control and regulate diverse aspects of plant processes."--Book cover Front Matter....Pages i-viii Small RNAs in Plants....Pages 1-28 Role of MicroRNA miR319 in Plant Development....Pages 29-47 The Roles of miR156 and miR172 in Phase Change Regulation....Pages 49-68 Roles of miR156 and miR172 in Reproductive Development....Pages 69-81 Trans -acting Small Interfering RNAs: Biogenesis, Mode of Action, and Role in Plant Development....Pages 83-108 Role of miRNAs in Seed Development....Pages 109-121 Genetic and Molecular Approaches to Assess MicroRNA Function....Pages 123-148 Functions of miRNAs in Rice....Pages 149-176 microRNA Regulation of Symbiotic Nodule Development in Legumes....Pages 177-195 Roles of miRNAs in Nutrient Signaling and Homeostasis....Pages 197-217 Role of microRNAs in Plant Adaptation to Environmental Stresses....Pages 219-232 Endogenous Small RNAs and Antibacterial Resistance in Plants....Pages 233-259 Role of Virus-Derived Small RNAs in Plant Antiviral Defense: Insights from DNA Viruses....Pages 261-289 Back Matter....Pages 291-296 Annotation Precise regulation of gene expression in both time and space is vital to plant growth, development and adaptation to biotic and abiotic stress conditions.
