The brown planthopper (BPH) is the most serious insect pest of rice in Asia. The indica rice cultivar ADR52 carries two BPH resistance genes, BPH26 (BROWN PLANTHOPPER RESISTANCE 26) and BPH25. Map-based cloning of BPH26 revealed that BPH26 encodes a coiled-coil-nucleotide-binding-site-leucine-rich repeat (CC-NBS-LRR) protein. BPH26 mediated sucking inhibition in the phloem sieve element. BPH26 was identical to BPH2 on the basis of DNA sequence analysis and feeding ability of the BPH2-virulent biotype of BPH. BPH2 was widely incorporated in elite rice cultivars and was well-cultivated in many Asian countries as a favorable gene resource in rice breeding against BPH. However, BPH2 was rendered ineffective by a virulent biotype of BPH in rice fields in Asia. In this study, we suggest that BPH2 can be reused by combining with other BPH resistance genes, such as BPH25, to ensure durable resistance to BPH.
