-Compared with dominant resistance genes to BPH, little progress has been made in recessive resistance genes. Fine mapping of BPH27 on chromosome 4, therefore, provides valuable information for understanding the molecular mechanisms underlying the recessive gene-mediated resistance. Candidate genes in the fine-mapped region by sequencing parental lines and transforming susceptible parent with cloned BPH27 candidate genes still need to be vindicated. Moreover, a number of simple molecular markers will be exploited to support in the development of rice cultivars that are resistant to multiple BPH biotypes.

		+	The brown planthopper (Nilaparvata lugens Stål; BPH) is one of the most hazardous rice pests in the world. Growing resistant varieties is the most active way to deal with this insect, and wild rice species are a valuable source of resistance genes for developing resistant cultivars. BPH27 derived from an accession of Guangxi wild rice, Oryza rufipogon Griff. (Accession no. 2183, hereafter named GX2183), was primarily mapped to a 17-cM region on the long arm of the chromosome four. Furthermore, fine mapping of BPH27 was conducted using two BC1F2 populations derived from introgression lines of GX2183. Insect resistance was assessed in the BC1F2 populations with 6,010 individual off springs, and 346 resistance extremes were obtained and employed for fine mapping of BPH27. High-resolution linkage analysis discover the BPH27 locus to an 86.3-kb region in Nipponbare.
