"Characterization of groundnut resistance to bacterial-wilt caused by Ralstonia solanacearum by forward and reverse genetics methods"^^ . "Bacterial wilt caused by casual agent Ralstonia solanacearum (Rs)\r\nis a serious disease in groundnut and great many other plant species.\r\nForward and reverse genetics strategies were adopted in\r\nour study. From the view point of forward genetics, the peanut\r\nRILs including 300 F9 progenies derived from Yueyou 92 × Xinhuixiaoli\r\nwere tested of disease resistance through inoculation\r\nwith R.solanacearum in the field. Resistance to R.solanacearum\r\nis a quantitative trait. Three QTLs were mapped on an interval\r\n15 cM using a linkage map with SSR and related SNP markers.\r\nAn Tir-NBS-LRR resistance gene AhqBW3 was found closely\r\nlinked with a BW resistance molecular marker SNP79 which was\r\nmapped in a gene locus next to the R gene. AhqBW3 was showed\r\ndownregulation under the challenge of Rs inoculation. From the\r\nview point of reverse genetics, a novel NBS-LRR resistance gene\r\nAhRRS5, an LRR-RLK gene AhRLK1 and an unkown gene AhRRS22\r\nwere upregulated by Rs inoculation which were screened from\r\nmicroarray hybridization. They showed resistance phenotypes in\r\ntransgenic tobacco overexpressing of these three genes. Among\r\nof them, Overexpression of AhRRS5 significantly enhanced the\r\nresistance of heterogeneous tobacco to R. solanacearum, with\r\ndiverse resistance levels in different transgenic lines. Several\r\ndefense-responsive marker genes in hypersensitive response,\r\nincluding HR, SA, JA, and ET signals, were considerably upregulated\r\nin the transgenic lines as compared with the wild type in response\r\nto R. solanacearum. NPR1 and NDR1 were also upregulated\r\nin response to the pathogen. These results indicate that AhRRS5\r\nparticipates in the defense response to R. solanacearum through\r\nthe crosstalk of multiple signaling pathways and the involvement\r\nof NPR1 and R gene signals for its resistance. These studies may\r\nguide the resistance enhancement of peanut and other economic\r\ncrops to bacterial wilt disease."^^ .
