This reference book compiles updated research on non-coding RNAs and their role in producing high-yielding plants with higher productivity under changing climates. Plant non-coding RNAs are emerging as the key regulators of plant responses to climate change and environmental stresses. The book covers the sequencing, identification, prediction, identification, characterization, and targets of non-coding RNAs to engineer high-yielding crops. It also includes in silico tools and databases to study them. Key features: Discusses the different types of non-coding RNAs including lnc-RNAs, siRNA, microRNAs, and tasiRNAs Covers the role of plant non-coding RNAs in epigenetic regulation of environmental stress response and tolerance Reviews the role of non-coding RNAs under environmental stresses like drought, water logging, salinity, extreme temperature, UV, heavy metals, and xenobiotics Explores the use of non-coding RNAs in transgenic crops and genome editing Describes the biogenesis, history, and classification of non-coding RNAs in plants The book provides a mix of basic and advanced information for postgraduate students, researchers, and scientists in the fields of plant molecular biology, biotechnology, food security, and agriculture.
