AI Article Synopsis
- MicroRNAs (miRNAs) are small RNA molecules that play a significant role in regulating gene expression in both plants and animals by binding to messenger RNAs (mRNAs) to suppress their activity.
- Recent research has uncovered that plant-derived miRNAs can influence insect gene expression, leading to debates about their impact on insect development and coevolution between plants and insects.
- The review explores the processes of miRNA production, their roles in plant-insect interactions, and their potential applications in pest management and crop improvement, while also addressing existing controversies in the field.
Article Abstract
MicroRNAs (miRNAs), a class of non-coding small RNAs, are crucial regulatory factors in plants and animals at the post-transcriptional level. These tiny molecules suppress gene expression by complementary oligonucleotide binding to sites in the target messenger. Recently, the discovery of plant-derived miRNAs with cross-kingdom abilities to regulate gene expression in insects has promoted exciting discussion, although some controversies exist regarding the modulation of insect development by plant-derived miRNAs. Here, we review current knowledge about the mechanisms of miRNA biogenesis, the roles of miRNAs in coevolution between insects and plants, the regulation of insect development by plant-derived miRNAs, the cross-kingdom transport mechanisms of plant-derived miRNAs, and cross-kingdom regulation. In addition, the controversy regarding the modulation of insect development by plant-derived miRNAs also was discussed. Our review provides new insights for understanding complex plant-insect interactions and discovering new strategies for pest management and even crop genetic improvement.
