Abstract
Environmental stresses adversely impact the growth and productivity of rice crops worldwide. Therefore, rice evolved several mechanisms to acclimatize environmental challenges by altering gene expression and metabolism. Keeping in mind the complexity of regulatory networks, researchers have investigated the role of long noncoding RNA (lncRNA) and consider it as an important regulator for various biological functions and developmental processes under unstressed as well as stressed conditions. LncRNAs perform these biological functions by transcriptional, posttranscriptional regulation, and epigenetic modification, i.e., histone-modifications, DNA-methylation, antisense-transcription, etc. In rice, several recent studies reported the characterization of lncRNA in homologous as well as heterologous system and identified their role in the regulation of gene expression, which ultimately results in better growth and survival of crops. Among the numerous reports published on lncRNAs, this review preferentially focuses on recent advancements in lncRNA-mediated stress tolerance in rice and also highlights the research opportunities in this area.
