水稻抗褐飞虱基因Bph9及其分子标记和应用
摘要：
本发明提供了水稻抗褐飞虱基因Bph9及其分子标记和应用。其具有SEQ ID No.1所示的核苷酸序列，其cDNA序列如SEQ ID No.2所示。Bph9基因定位于分子标记InD2和RM28466之间。与该基因紧密连锁的分子标记还有RM28438、InD28450、InD28453、InD14、InD28432、RM28481和RM28486之一，可用于筛选含有抗褐飞虱基因Bph9的水稻。Bph9基因属于NBS-LRR基因家族，编码的蛋白质与植物抗病性相关，通过遗传转化和杂交，将Bph9基因转入普通水稻品种，能够提高水稻对褐飞虱的抗性，从而减轻褐飞虱产生的危害，达到增产和稳产的目的。
摘要（英）：

The invention provides a brown planthopper resistant rice gene Bph9 as well as a molecular marker and application thereof. The brown planthopper resistant rice gene Bph9 has a nucleotide sequence as shown in SEQ ID No.1 and a cDNA (complementary Desoxvribose Nucleic Acid) sequence as shown in SEQ ID No.2. The Bph9 gene is located between molecular markers InD2 and RM28466. The molecular markers closely linked with the gene also includes one of RM28438, InD28450, InD28453, InD14, InD28432, RM28481 and RM28486 which can be used for sieving the rice containing the brown planthopper resistant gene Bph9. The Bph9 gene belongs to the NBS-LRR (Nucleotide Binding Site-Leucine Rich Repeat) gene family; the encoded protein is related to the plant disease resistance; the Bph9 gene is transferred into common rice by virtue of genetic transformation and hybridization, and thus the resistance of rice to brown planthopper can be improved, so that the damage of brown planthopper is decreased, and the purposes of yield increase and yield stabilization are realized.
