Descripción
"Dear Editor,
Long noncoding RNAs (lncRNAs) are emerging as critical regulators of plant growth and development, and their expression orchestrates and integrates multiple processes underlying vital components of the phenotype, including stress adaptation, aspects of phenotypic evolution, and speciation.1 In plants, lncRNA-mediated gene regulation remains poorly understood, even in rice, one of the most important staple foods and a model crop species. In this study, we performed strand-specific RNA sequencing of 188 accessions representing different developmental stages of cultivated (Oryza sativa ssp. japonica and indica) and wild rice (O. rufipogon). We identified a total of 57,162 lncRNAs in the rice genome, established a comprehensive lncRNA annotation resource, and analyzed the molecular mechanisms by which lncRNAs regulate gene expression and influence key agronomic traits. Subsequent functional validation suggested that the lncRNA LBR5 may confer resistance to bacterial blight. This study advances our understanding of the role of the noncoding genome in shaping phenotypic diversity and evolutionary adaptation in rice."
