INTRODUCTION: The brown planthopper (BPH) is a highly destructive pest in rice production. The widespread cultivation of resistant rice varieties drives BPH populations to evolve new biotypes, posing a continuous challenge to crop protection. Understanding the adaptation mechanisms of these biotypes is therefore critical.
OBJECTIVES: This study aimed to investigate the potential mechanisms underlying the adaptation of a new BPH biotype to resistant rice varieties.
METHODS: We compared the host adaptability of Biotype 1 and Biotype Y on a resistant rice variety (carring Bph15). An integrative multi-omics approach (transcriptomic and metabolomic) was employed, alongside metagenomic analysis of symbiotic microbiota.
RESULTS: Biotype Y exhibited superior adaptation to the resistant variety. Multi-omics analysis revealed that the adaptation was associated with upregulation of carbohydrate, detoxification, and energy metabolism pathways, downregulation of vitamin pathways, and a distinct symbiotic microbiota enriched in Wolbachia. Functional experiments provided evidence suggesting that Wolbachia may contribute to this enhanced adaptation, possibly through riboflavin supplementation.
CONCLUSION: The adaptation of BPH to resistant rice appears to be associated with coordinated transcriptional and metabolic reprogramming, potentially involving symbiont-mediated nutritional support. These findings may provide new insights into tripartite host-pest-microbiota interactions and offer potential targets for sustainable pest management strategies.
